  • New Dell Vostro 3550 will not boot into Live CD

    - by rich97
    I've been trying to install Ubuntu and/or it's derivatives on my new Dell Vostro 3550 but I'm finding it impossible to boot into the live CD environment. Here are the things I've already tried: Booting from multiple versions of multiple distributions (Ubuntu 10.10, Ubuntu 11.04, Mint 11, Mint 10) Booting from a Live USB created with unetbootin, the Linux Mint startup disk creator, the universal USB creator and dd of=linuxmint.***.iso if if=/dev/sdx. Burning a CD and booting from the internal CD drive. In the case of the USB keys with the latest versions of Ubuntu it gets to the page where I can select a boot option, but after selecting an option the screen goes black, even the back light turns off. With the older distributions the screen stays on but it starts loading and then just hangs. The CDs don't even try to boot. It starts spinning but then falls back to the default Windows install. The only way I've got it to work so far is with Wubi, but that's hardly ideal. I'd like to have two separate physical partitions with a /home and /. Any help is appreciated. Thank you.

  • 12.0.4.3 - Missing Battery Icon, auto Suspend not working, Keyboard shortcuts volume up/down no longer working

    - by Navraj
    Problems I am experiencing: Battery Icon not showing up unity bar (top right corner). Volume Up/Down/Mute not working. Bluetooth hot keys described above also not working.Brightness up/down keys on this keyboard no longer working (apple wireless keyboard) Laptop no longer suspends when lid is shut. I have to go to 'power' button on top right corner and click on 'Suspend' All was working flawlessly until I did the following: I have recently upgraded to Nvidia propriety driver version 319 {version recommended}. Installed Xscreensaver and then removed it and went back to default screensaver. Done a system update (1st since installing) and now currently running: Linux 3.8.0-32-generic #47~precise1-Ubuntu SMP Wed Oct 2 16:19:35 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux NOTE: Base system was ubuntu 12.04.3 installed from ISO however lsb_release reports "No LSB modules are available" 4.installed psensor. I have check power setting (via Settings) and power setting via dconf-editor and set to recommended settings as described in posts detailing solution to this problem. - I have disabled 1) Nvdia settings at startup and 2) psensor at startup but this does not help. I am using an HP DV7 with 2GB Nvidia card. Not using any fancy graphics features. Recommendations? Thanks.

  • System testing - making sure the system conforms to specification. Validation?

    - by user970696
    After weeks of research I have nearly completed my thesis, yet I am unable to clear up my confusion contained in all previous threads here (and in many books): During system testing, we check the system function against system analysis (functional system design) - but that would fit to a definition of verification according to many books. But I follow ISO12207, which considers all testing as validation (making sure work product meets requirement for intended use). How can I justify that unit testing or system testing is validation, even though when I check it against specification? Which fullfils the definiton of verification? When testing that e.g. "Save button" works, is it validation? This picture shows my understanding of V&V, so different from many other sources, including ISTQB etc. Essential problem I have is that a book using the same picture also states on another place that: test activities in the area of validation are usability, alpha and beta testing. For verification, testable system requirements are defined whose correct implementation can be tested through system tests. Isn't that the opposite of what the picture says? Most books present the following picture, where validation is just making sure that customer needs are satisfied. Mind you that according to ISO, validation activity is testing.

  • ubi-partman failed with exit code 10 during 12.10 fresh install

    - by Austen
    ive been trying to install ubuntu 12.10 on my acer aspire one 534h,using an iso from the official site and a 16gb flash drive using unetbootin. my aa1 is running factory settings (xp). it will boot fine from the usb, but the installation throws the error in the title after choosing my wifi options, and contineus to give the error after every subsequent step. after trying to complete the installation ingoring the error, it hangs on the ask ubuntu screen. ive tried reformatting and reflashing (sorry, heavy android user) ubuntu to the flash drive, to no avail... do i need to format somthing else, or is it something to do with th Hdd and RAID drives? ive looked in my BIOS and found nothing related. only the option for sata or ide... any help would be great, as ive been working at this all day... edit: the error message was ubi-partman has failed with exit code 10. see (gave a directory) for more info. it then informed me that if i continued the install could be incomplete or completly broken. not sure abouth the wording in the second part, but the error is word for word... thank you.

  • Shutdown issue on persistent LiveUSB

    - by John K
    A) Downloaded Ubuntu to a Windows 7 temp directory from: http://www.ubuntu.com/download/ubuntu/download (Ubuntu 11.10 - Latest version / 32-bit). The output was a .iso file. B) Created a bootable USB stick using Universal USB Installer: http://www.pendrivelinux.com/universal-usb-installer-easy-as-1-2-3/. Did not select "Persistent file". Result: Tried it in a Dell Latitude D630 Dell laptop: works every time, many startups and shutdowns. C) Repeated B) but with "Persistent file" set. Works once or twice, but then, just locks on the Ubuntu splash screen. E) Downloaded LiveUSB Install from http://live.learnfree.eu/download, which created a file on Windows 7 called live-usb-install-2.3.2.exe. F) Ran the above installer with "Persistent file" to a 4GB ScanDisk (formatted) thumb drive. Result: Worked pretty good for a while. Shutdown and rebooted several times. Changed items like creating a new directories - all worked. Then: Setup an Admin account with a password and no auto login. On next reboot, it required the password and logged in correctly. Tried to shutdown via the top left icon - Shutdown menu option. Key issue: Would not shutdown, but would always go back to the login prompt. Could successfully login. Finally, shutdown (which just put me back to the login window), and hard shutdown with the power switch. Result: On reboot, just locks on the Ubuntu splash screen. Questions (note, very new to Linux): Did I shutdown wrong (I mean prior to the hard power off)? Is the persistence option very unstable, or am I doing something else completely wrong?

  • Can I install new version of Ubuntu in spair RAIDed partition with unetbootin

    - by artfulrobot
    I have Ubuntu 11.04 running on my home desktop which has 2 hard drives mirrored by RAID. The drives are partitioned with a big data partition, a swap partition and a couple of 20Gb partitions for OSes, one is 11.04 which is in use, and the other is kept spare for installing a later version. Which is what I'd like to do now. The idea of a 2nd partition for new OS is that I can try it, and if it's problematic, I can boot back into the original one - the machine is shared with others, so I need it to stay available! I have had horrible problems with software RAID after using a Live USB stick - basically it messes up the internal numbering of the RAID drives or something, anyway, the result is you can't boot after using it :-( and have to spend ages re-assembling the arrays, trying to remember grub commands etc etc. Quite a shocker when you consider booting from a Live USB is supposed not to affect the existing system. As I'm installing in a RAIDed disc, I would typically use the Alternative install (sad to hear that this is going to be dropped in future). However, I think I might be able to use unetbootin to trick the system into working on top of the existing system that understands RAID, with the normal ISO? If unetbootin loads from drives that are already understood to be RAIDED, then presumably it will only see md0... instead of sda, sdb... and as long as I don't need to repartition (I don't) it should be fine, right? Or is that just plain foolishness? Please tell me before I end up with a dead system (again!)

  • How to get Visual Studio 2010 Express Edition on Windows 7

    - by thanigai
    Visual studio 2010 is an amzing release from Microsoft. I have tried the beta 1,2 of Visual Studio 2010 and finally the full version is released. I am also interested in the latest edition of Windows which nothing but our Windows 7. Next to Vista I like this version very much. Out of curiosity I have installed the prebuild version of Windows 7. I tried installing the express edition here and it failed making me disappointed. I tried two or three times and finally I decided to download the trial version of Windows 7. After that I can install the Visual Studio 2010 express edition easily. I have given the link below from where I have downloaded the file. http://www.microsoft.com/express/downloads/ Here the link give is through Web PI Installer. Other option is you can download the ISO image file and burn them to a disc or use a virtual disc This Visual Web developer will provide the Sql Server engine alone. To get a Sql Server Management Studio get from the following link http://www.microsoft.com/express/Database/InstallOptions.aspx That's it all the things necessary for the web application programming is ready. Ah I forget to tell about the Silverlight. Please find the Silverlight 4 latest tools from the below link (WCF RIA services is the main update) http://www.silverlight.net/getstarted/ Silverlight 4 Tools(http://www.microsoft.com/downloads/details.aspx?FamilyID=eff8a0da-0a4d-48e8-8366-6ddf2ecad801&displaylang=en) Expression Blend 4 trial(http://www.microsoft.com/downloads/details.aspx?FamilyID=88484825-1b3c-4e8c-8b14-b05d025e1541&displaylang=en) I think the reader would have enjoyed on how to get these things. Please let me know if you are not clear with any of these things.  Thanks, Thani

  • Botting from a stick drive

    - by Zap
    Am trying to boot from a usb stick. Have carefully followed the instructions at the following link and successfully downloaded and installed version Ubuntu 12.04 desk top: http://www.ubuntu.com/download/help/create-a-usb-stick-on-windows I used the Universal-USB-Installer-1.9.0.2 as instructed and choose the "Ubuntu 12.04 desk top" option, after downloading the respective iso/zip file onto my Dell laptop from the Ubuntu site. Also modified my bios to select the usb first as boot drive instead of hard drive. Also, turned off bit blocker on my laptop and usb stick. Usb stick has the setting of "Automatically unlock this drive on this computer". When i reboot my laptop, it first boots into a black screen (i assume is the bios), but prompts saying "Remove disks or other media. Press any key to start". I press any key and regardless the laptop boots up to windows. Hence, it appears that the boot process is checking the USB first before going to the hard drive to look for it's boot disk and starting Windows 7. Is it that the USB stick is not correctly configured with Ubuntu as a boot disk? Is there anything else that i need to do besides the instructions at the following link? http://www.ubuntu.com/download/help/create-a-usb-stick-on-windows How can I ensure that USB boot stick is configured correctly? After running the Universal-USB-Installer-1.9.0.2 to "install" Ubuntu, is there additional configuration/installation steps? What is the first file that the bios would look for on this USB drive? Is this configured somewhere in the bios, or would it just look for an grub file or /boot dir? The only message i get when booting is "Remove disks or other media. Press any key to start". Any and all help would be much appreciated.. Thanks ... :)

  • PCI Compliance Book Suggestion

    - by Joel Weise
    I am always looking for good books on security, compliance and of course, PCI.  Here is one I think you will find very useful. "PCI Compliance, Third Edition: Understand and Implement Effective PCI Data Security Standard Compliance" by Branden Williams and Anton Chuvakin.  [Fair disclosure - Branden and I work together on the Information Systems Security Association Journal's editorial board.]   The primary reason I like this book is that the authors take a holistic architectural approach to PCI compliance and that to me is the most safe and sane way to approach PCI.  Using such an architectural approach to PCI is, in my humble opinion, the underlying intent of PCI.  Don't create a checklist of the PCI DSS and then map a solution to each.  That is a recipe for disaster.  Instead, look at how the different components and their configurations work together in a synergistic fashion.  In short, create a security architecture and governance framework (the ISO 27000 series is a good place to start) that begins with an evaluation of the requirements laid down in the PCI DSS, as well as your other applicable compliance, business and technical requirements.  By developing an integrated security architecture you should be able to not only address current requirements, but also be in a position to quickly address future ones as well.

  • Lubuntu 12.04 on Acer laptop boots to blank blue screen

    - by WGCman
    My previous question on this was closed, but I am posting it again as the solution which my son eventually found may assist other users of the forum, or someone may be able to tweak the solution to improve the performance. Having installed Kubuntu 12.04.01 from a live USB onto my desktop, I wanted to do the same on my laptop, an Acer Aspire 1362 Laptop, which has 256MB RAM (actually 512 "on the box", but a good deal can be borrowed by the graphics!). I found Kubuntu wouldn't run on so little memory but downloaded: Lubuntu-12.04-alternate-i386.iso, which I understood was light enough to go. The laptop has one internal 40GB Toshiba hard drive divided into 3 partitions: C,19GB with Windows XP, Windows program files and some data, D, 19GB mostly data, and a small 2GB partition with some Acer software, which XP can't normally “see”. I transferred most of the contents of D to a memory stick, leaving 16GB free for Lubuntu. I did not want to dump XP yet, though it is painfully slow. I installed Lubuntu from then USB stick, accepting the default answers to most of the questions. The D: partition was further partitioned into a 500MB boot partition, 10GB for Linux, 2GB Swap and 6GB for data shareable between Linux and Windows. I had no error messages during installation, rebooted, was offered the choice of Ubuntu or XP, and selected the former. After a few minutes, I get a dark blue screen announcing Lubuntu with five dots underneath which lighten in turn. Eventually the lights stopped, and whatever I try the screen remains blank apart from “Lubuntu” I tried several solutions suggested on the forum for “identical” questions but without success.

  • how to create a mirror of minimum size to install Ubuntu

    - by Registered User
    I need to create an http url at my laptop to have a Ubuntu installation begin within my laptop on a Xen environment. This is how the final thing will look like http://bderzhavets.wordpress.com/2008/10/28/install-ubuntu-intrepid-server-pv-domu-at-xen-33-port-via-httpgetco-centos-52-dom0/ the host and client are both going to be my laptop, I Google d and came across apt-mirror and some other packages. I do not want to archive entire 15 GB Ubuntu repositories on my machine. It is not possible to use a CD,ISO,loop mounted disk (reason mentioned below). I have tried using netboot image on local machine which failed because if you are attempting to create a virtual machine on a hardware which does not support VT virt-manager installer necessarily needs a URL of this sort http://archive.ubuntu.com/ubuntu/dists/hardy/main/installer-i386/current/images/netboot/ any other option to create guest OS is simply grayed out. The unfortunate part is my Ethernet connections do not work when I boot with Xen-4.0 and a pv-ops Dom0 kernel from Jeremy's tree.Which is where I have to do this work.So I have to create a URL structure which is similar to Ubuntu mirrors.So how can I do this in bare minimum so that at least the console boots and once the console comes I can do some work.

  • Using 12.04 installation as a persistent pen drive

    - by Cawas
    Disclaimer: I aim to build a self contained pen drive with my application inside, so no matter about updates. Maybe I'm looking at the wrong linux distribution to do this... Please let me know if you think so. I've tried knoppix and even lubuntu, but they don't come with enough "drivers" for Unity3D to work. Creating a custom live persistent pen drive is a real pain and I'm trying for 1 day without any success. Sure, being able to do it would probably be ideal and occupy the minimum space. Using the installation image on a pen drive, however, is good enough and is really easy to create. We can even do it from any OS, using UNetBootin, LiLi USB Creator or some other methods. Straight forward. Some recommend installing it on a pen drive. But that requires a lot of space and, I believe, it won't behave as good as something meant to be installed on a usb disk, because of memory management. So, there are only a few negative points on using the installation image that I can think of. Question here, is how to remove those drawbacks: Having to press "Try Ubuntu". That's the big one. Couldn't find how. Unable to load everything on memory and keep on running without the pen drive (like this) Unable to remove "Install Ubuntu 12.04 LTS" app. Setting the ISO to use maximum amount of space for the OS will leave pen drive with zero space left and any file saved within it from ubuntu is inaccessible from the outside (when plugin the pen drive and not booting from it). Am I missing something? Can those points be fixed?

  • Fix: Cant Change or Remove Visual Studio 2008 from DVD

    If you installed Visual Studio 2008 on a 64-bit operating system, you may have trouble when you try ad add or remove functionality by inserting the disk (or remounting the ISO image).  I believe this is because of the path used to install the 32-bit Visual Studio program.  When you run the setup.exe off of the disk, you get this: Clicking on Change or Remove Visual Studio 2008 brings up this dialog: But not long after it appears, it disappears to be replaced with: Microsoft Visual Studio 2008 Setup A problem has been encountered while loading the setup components.  Canceling setup. FIX: Use Add or Remove Programs Launch the Add or Remove Programs dialog in Windows, and find Microsoft Visual Studio Team System 2008 Team Suite ENU (or whichever SKU you installed).  Click Uninstall/Change.  From here you should be able to change your installed components of Visual Studio successfully: Thanks to Brendan for the tip! Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight. Take a look: here.

  • What's wrong with cplusplus.com?

    - by Kerrek SB
    This is perhaps not a perfectly suitable forum for this question, but let me give it a shot, at the risk of being moved away. There are several references for the C++ standard library, including the invaluable ISO standard, MSDN, IBM, cppreference, and cplusplus. Personally, when writing C++ I need a reference that has quick random access, short load times and usage examples, and I've been finding cplusplus.com pretty useful. However, I've been hearing negative opinions about that website frequently here on SO, so I would like to get specific: What are the errors, misconceptions or bad pieces of advice given by cplusplus.com? What are the risks of using it to make coding decisions? Let me add this point: I want to be able to answer questions here on SO with accurate quotes of the standard, and thus I would like to post immediately-usable links, and cplusplus.com would have been my choice site were it not for this issue. Update: There have been many great responses, and I have seriously changed my view on cplusplus.com. I'd like to list a few choice results here; feel free to suggest more (and keep posting answers). As of June 29, 2011: Incorrect description of some algorithms (e.g. remove). Information about the behaviour of functions is sometimes incorrect (atoi), fails to mention special cases (strncpy), or omits vital information (iterator invalidation). Examples contain deprecated code (#include style). Inexact terminology is doing a disservice to learners and the general community ("STL", "compiler" vs "toolchain"). Incorrect and misleading description of the typeid keyword.

  • How to apply verification and validation on the following example

    - by user970696
    I have been following verification and validation questions here with my colleagues, yet we are unable to see the slight differences, probably caused by language barrier in technical English. An example: Requirement specification User wants to control the lights in 4 rooms by remote command sent from the UI for each room separately. Functional specification The UI will contain 4 checkboxes labelled according to rooms they control. When a checkbox is checked, the signal is sent to corresponding light. A green dot appears next to the checkbox When a checkbox is unchecked, the signal (turn off) is sent to corresponding light. A red dot appears next to the checkbox. Let me start with what I learned here: Verification, according to many great answers here, ensures that product reflects specified requirements - as functional spec is done by a producer based on requirements from customer, this one will be verified for completeness, correctness). Then design document will be checked against functional spec (it should design 4 checkboxes..), and the source code against design (is there a code for 4 checkboxes, functions to send the signals etc. - is it traceable to requirements). Okay, product is built and we need to test it, validate. Here comes our understanding trouble - validation should ensure the product meets requirements for its specific intended use which is basically business requirement (does it work? can I control the lights from the UI?) but testers will definitely work with the functional spec, making sure the checkboxes are there, working, labelled, etc. They are basically checking whether the requirements in functional spec were met in the final product, isn't that verification? (should not be, lets stick to ISO 12207 that only validation is the actual testing)

  • Is the Alternate Ubuntu installer still required for LVM or Software RAID setup?

    - by jimp
    Over the past 5 years, I have been setting up Ubuntu servers using the Alternate installer. I need to provision a new server today, and I'm curious if the Alternate CD is still the only way to setup LVM/RAID at installation time. I'm my limited experience with Red Hat Enterprise Linux, I noticed it's single installer configures LVM automatically. Has Ubuntu's installer, at least the standard "Server" installer, added support for LVM/RAID, or is the Alternate installer still required for that kind of server setup? http://mirror.anl.gov/pub/ubuntu-iso/DVDs/ubuntu/12.04.1/release/ Alternate install CD The alternate install CD allows you to perform certain specialist installations of Ubuntu. It provides for the following situations: setting up automated deployments; upgrading from older installations without network access; LVM and/or RAID partitioning; installs on systems with less than about 384MiB of RAM (although note that low-memory systems may not be able to run a full desktop environment reasonably). LVM has always been fundamental for our server needs, so I'm surprised if it is still not considered a server-worthy feature.

  • Why does Ubuntu 13.10 not detect my Win7 partition?

    - by goutham
    I'm trying to install Ubuntu 13.10 alongside Windows 7 on my DELL INSPIRON 14z 5423 laptop and I'm new to all of this. I'm using the Ubuntu 13.10 64-bit ISO burned onto a CD. The first time I tried to install it, Ubuntu said it did not detect any other OS, which meant I only had 4 options: Erase disk and install Ubuntu (I don't want to do this) Encrypt new Ubuntu. Use LVM. Something else. If I choose the Something else option, it brings me to the partition menu and says that I have 1 disk with free space of (500Gb), but that's not true because I have Windows 7.

  • How to install Ubuntu 12.04.1 in EFI mode with Encrypted LVM?

    - by g0lem
    I'm trying to properly install Ubuntu 12.04.1 LTS 64-bit PC (AMD64) with the alternate install CD ".iso" on a lenovo Thinkpad X220. Default Hard Disk (with a pre-installed version of Windows 7) has been replaced with a brand new SSD. The UEFI BIOS of the lenovo Thinkpad X220 is set to "UEFI Boot only" & "USB UEFI BIOS Support" is enabled (I'm using an external USB DVD reader to perform Ubuntu installation). The BIOS is a Phoenix SecureCore Tiano, BIOS version is 8DET56WW (1.26). The attempts below are made with the UEFI BIOS settings described above. Here's what I've tried so far: Boot on a live GParted CD Create a GPT partition table Create a FAT32 partition for UEFI System, set the partition to "EF00" type ("boot" flag) Leave remaining space unformated Boot on Ubuntu 12.04.1 LTS 64-bit PC (AMD64) with alternate CD: Perform the install with network updates enabled Use manual partitioning FAT32 partition created with GParted is used as "EFI System partition" Remaining space is set to be used as "Physical volume for LVM" Then "Configure encrypted volumes" using the previous "Physical volume for LVM" as the encrypted container, passphrase is setup. "Configure the Logical Volume Manager" creating a volume Group using the encrypted container /dev/mapper/sda2_crypt Creation of the Logical Volumes "Create logical volume", choosing the previously created volume Group Assign a mount point and file system to the Logical volumes : LV-root for / LV-var for /var LV-usr for /usr LV-usr-local for /usr/local LV-swap for swap LV-home for /home NOTE: /tmp would be in RAM only using TMPFS Bootloader step: neither my ESP partition (/dev/sda1, /dev/sda or MBR) seems to be the right place for GRUB, I get the following message (X suffix is for demonstration only): unable to install grub in /dev/sdaX Executing 'grub-install /dev/sdaX' failed This is a fatal error. Finish installation without the Bootloader & Reboot The system doesn't start, there's no EFI/GRUB menu at startup. What are the steps to perform a clean and working installation of Ubuntu 12.04.1 Precise Pangolin, 64bit version in U(EFI) mode using the encrypted LUKS + LVM scheme described above?

  • Is there a canonical source supporting "all-surrogates"?

    - by user61852
    Background The "all-PK-must-be-surrogates" approach is not present in Codd's Relational Model or any SQL Standard (ANSI, ISO or other). Canonical books seems to elude this restrictions too. Oracle's own data dictionary scheme uses natural keys in some tables and surrogate keys in other tables. I mention this because these people must know a thing or two about RDBMS design. PPDM (Professional Petroleum Data Management Association) recommend the same canonical books do: Use surrogate keys as primary keys when: There are no natural or business keys Natural or business keys are bad ( change often ) The value of natural or business key is not known at the time of inserting record Multicolumn natural keys ( usually several FK ) exceed three columns, which makes joins too verbose. Also I have not found canonical source that says natural keys need to be immutable. All I find is that they need to be very estable, i.e need to be changed only in very rare ocassions, if ever. I mention PPDM because these people must know a thing or two about RDBMS design too. The origins of the "all-surrogates" approach seems to come from recommendations from some ORM frameworks. It's true that the approach allows for rapid database modeling by not having to do much business analysis, but at the expense of maintainability and readability of the SQL code. Much prevision is made for something that may or may not happen in the future ( the natural PK changed so we will have to use the RDBMS cascade update funtionality ) at the expense of day-to-day task like having to join more tables in every query and having to write code for importing data between databases, an otherwise very strightfoward procedure (due to the need to avoid PK colisions and having to create stage/equivalence tables beforehand ). Other argument is that indexes based on integers are faster, but that has to be supported with benchmarks. Obviously, long, varying varchars are not good for PK. But indexes based on short, fix-length varchar are almost as fast as integers. The questions - Is there any canonical source that supports the "all-PK-must-be-surrogates" approach ? - Has Codd's relational model been superceded by a newer relational model ?

  • Ubuntu installed along side Win 8 but not shown in boot

    - by Mahesha999
    Actually the question says it all, but let me tell you what I did, so u may find exactly what might have went wrong: I have Win 8 installed on 500 GB HDD. SO I shrunk it four times for: partition 1 - the original partition containing Win 8 sys (118GB) partition 2 - NTFS formatted for my data (188GB) partition 3 - NTFS formatted for my data (100GB) partition 4 - NTFS formatted for Linux distro 1 (I reformatted it to ext4 during Ubuntu installation) (25GB) partition 5 - NTFS formatted for Linux distro 1 (21GB) So now I booted Ubuntu from USB (created from ubuntu-12.04-desktop-amd64.iso) and deleted last two partitions 4 and 5 to create: partition 1 - ext4 where I installed Ubuntu (25GB) partition 2 - Swap (4GB) partition 3 - unallocated space, not formatted yet (17GB) Ubuntu installation said it installed successfully and that I have to restart to boot in Ubuntu. But when I restart Windows 8 auto booted - there was no dual boot. After that I devided above 100GB partition to 80Gb and 20GB ones (since I read online that I should have /home in separate partition for convenience, so I created 20GB partition for it) So I went on to manually create boot entry using EasyBCD as below show in picture at below link http://s19.postimage.org/dof2zuvw3/Free_BCD.png When I created the entry, FreeBCD showed the information as follows: Windows Boot Manager -------------------- identifier {9dea862c-5cdd-4e70-acc1-f32b344d4795} device partition=\Device\HarddiskVolume2 description Windows Boot Manager locale en-US inherit {7ea2e1ac-2e61-4728-aaa3-896d9d0a9f0e} integrityservices Enable default {ea8167ad-d189-11e1-90e4-ab2f09569dcc} resumeobject {ea8167a3-d189-11e1-90e4-ab2f09569dcc} displayorder {ea8167ad-d189-11e1-90e4-ab2f09569dcc} {ea8167b1-d189-11e1-90e4-ab2f09569dcc} toolsdisplayorder {b2721d73-1db4-4c62-bf78-c548a880142d} timeout 10 displaybootmenu Yes Windows Boot Loader ------------------- identifier {ea8167ad-d189-11e1-90e4-ab2f09569dcc} device partition=C: path \Windows\system32\winload.exe description Windows 8 locale en-US osdevice partition=C: systemroot \Windows resumeobject {9bc7fdf7-3ae0-11e2-be77-806e6f6e6963} Real-mode Boot Sector --------------------- identifier {ea8167b1-d189-11e1-90e4-ab2f09569dcc} device partition=C: path \NST\AutoNeoGrub0.mbr description Ubuntu Notice the last bolded entry created.

  • Help with dual booting Windows 8.1 Professional and Ubuntu 13.10

    - by user1292548
    I recently installed a clean version of Windows 8.1 Professional on my Lenovo Y500 (with Samsung 256GB 840 Pro SSD). I have Windows all set up and running normally. I am trying to dual boot Windows 8.1 and Ubuntu 13.10, but the installation procedure don't allow me to either "Install alongside..." or shows my SSD partitions correctly when I chose the "Something Else" option. I have created a 25GB partition of free space in the Windows disk manager, but on the installation screen on Ubuntu, it shows the whole drive as a free space. I have tried installing with a burned .ISO disk and a bootable USB, the results are the same for both. Windows Disk Management screen: http://imageshack.us/a/img855/9504/59zu.jpg The Ubuntu installation screen: http://imageshack.us/a/img62/2712/9g6i.jpg I've ran into this problem before when trying to dual boot Ubuntu and Windows 7 Professional a month ago. But I gave up and never resolved the issue. --EDIT-- I tried what Eero Aaltonen suggested, and this is my result: ubuntu@ubuntu:~$ sudo parted /dev/sda print Warning: /dev/sda contains GPT signatures, indicating that it has a GPT table. However, it does not have a valid fake msdos partition table, as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table, and are now using an msdos partition table. Is this a GPT partition table? Yes/No? yes Model: ATA Samsung SSD 840 (scsi) Disk /dev/sda: 256GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags ubuntu@ubuntu:~$

  • WiFi can't connect after suspend

    - by CyberOPS
    I've had this problem since Ubuntu 11.10 (my first install) but I was able to get around this issue with this answer. After I installed Ubuntu 12.04.1 I tried to use the same fix as before but I couldn't get it to work. I've also tried a couple other different fixes I found around the web but they didn't work. Basically here's what happens: I can see all the networks in my area. When I try to connect to one of them it never connects, it keeps disconnecting. After a little bit it asks for the password again but its already filled in correctly. If I hit okay it will do the exact same thing again. So does anyone know how I can get this fixed? INFO: Computer: HP Pavilion dv6t-6b00 CTO Quad Edition Entertainment Notebook PC Network Card: Intel® Centrino® Wireless-N 1000 OS: Ubuntu 12.04.1 (x64) dual booting with Windows 7 (x64) (*Not using Wubi*) Wireless Card Driver: iwlwifi UPDATE: I was about to reinstall with the DVD I made with the ISO from the official source but discovered the same issue happens on the disc's Ubuntu preview feature. I still was unable to fix it as before. I also tried the Xubuntu demo, and the same. Re installing the driver hasn't worked either.

  • Using VirtualBox to test drive Windows Blue

    - by Fat Bloke
    Oracle VM VirtualBox is great for trying out the latest and greatest technologies and platforms. So when Microsoft recently announced the Developer Preview for Windows Server 2012 R2 and Windows 8.1,  it was with eager anticipation that FatBloke ran to the TechNet Evaluation Center to download the isos. Once downloaded,  a new VM in VirtualBox Manager was created that used Windows 2012 (64-bit) OS type and all the defaults were selected. And on starting the VM, and pointing to the iso file to install from, the excitement rose as we saw a cool new splashscreen image: But suddenly our hopes are dashed.... It would seem that this platform requires an instruction (CMPXCHG16B) that VirtualBox doesn't offer "out-of-the-box".  Fear not, for the VirtualBox team knew that this day would finally arrive and have prepared an "in case of emergency" switch as follows: Power off the vm; At the command line type:  VBoxManage setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1 Start the VM and install Windows Server 2012 R2 This will be enabled by default in a future release, but geeks can't wait, hence this blog. Enjoy! -FB
