  • Windows Recovery from Grub messed up my computer?

    - by Hudson Worden
    Ok so I'm a noob when it comes to Operating Systems and I think I really messed up this time. So I have a laptop that dual boots Windows 7 and Linux Mint 11. I was trying to boot into Windows 7 but it would just have a black screen with a blinking cursor. So I turned off my computer and tried again. Still a black screen with a cursor. So I thought "well it must be broken somehow and I remembered seeing something like 'Windows Recovery' from the boot menu so I should try it." So when I turned on my computer a third time I selected 'Windows Recovery' (Something like that I can't remember exactly what it was called). After I had selected that I got a white Windows window that said in big red letters "ERROR". I turned off my computer again a turned it back on expecting the Grub menu to reappear. I was wrong. Instead I am greeted with error: no such partition grub rescue. Then I put in a live CD for ubuntu 11.04 and tried looking at my partitions using the disk manager. Looking at my partitions I notice that there isn't a Linux partition anymore and in its place is a unallocated space partition yet the Linux Swap partition is still there. My windows partition is still fine and I can access the files in it. If you understand what has happened, is there anyway I can get my files back? I don't care about reinstalling the OS again. I just want those files that are in the Linux Mint partition.

    - by Terzuz
    I had Windows 8, I installed Ubuntu for a new OS, Then I want to sadly go back to Windows , I have a Windows Vista *.iso but I can't boot from it. When I try to extract the '.iso file and have the contents on my USB so it can boot up , When I restart and click F9 for my Boot Device Options , Only my Hard Drive and CD ROM are there but my "Generic Flash Drive" is not , But when I do not have Windows Vista '.iso on it , It will show up in the list. How can I make a partition of some sort, Provide instructions since I am new at this all , then I need to be able to use the Windows Vista installer and install Windows Vista, I would like Dual-Boot if possible. Info: I have the HP 2000 Laptop (Mine was removed from the Best Buy Website so the closest laptop to the specifications and the design is the link at the bottom) I am running Ubuntu 12.10. I have 4GB of RAM , 220 GB in my Hard Drive left , I have a USB Flash Drive which works sometimes , other times it fails. Note - I tried using GParted in Ubuntu but I had a problem where the main drive with 220 GB Free was locked , I am not sure what to do and can not find the correct forum. http://www.bestbuy.com/site/HP+-+Pavilion+15.6"+Laptop+-+4GB+Memory+-+320GB+Hard+Drive+-+Pewter/5043836.p?id=1218608951204&skuId=5043836

  • Any benefit of /home Ubuntu partition

    - by nightcrawler
    I want to have dual OS of Win8 & Ubuntu 12.10. Provided that Ubuntu can access ntfs partition of Windows but same can't be said about Windows this leads to a question mark on the significance of having /home partition while installing Ubuntu. As far as I know /swap & / are the two partitions directly used by Ubuntu to store programs, installation & stuff while the documents/media resides in /home. Now because Ubuntu releases are more frequent than Windows & updates needs backup & relate stuff, so I came to decision to not to use /home at all, rather keep all my documents/media in ntfs, which would be untouched while upgrading Ubuntu as Win updates are once in a decade! Is my thinking correct? If yes, what would be the minimum space I should allot to /home plus how much I should allot to / one must know that I plan to use heavy applications like Maple, Matlab & Sagemath on Ubuntu.

  • Is full partition encryption the only sure way to make Ubuntu safe from external access?

    - by fred.bear
    (By "external access", I mean eg. via a Live CD, or another OS on the same dual-boot machine) A friend wants to try Ubuntu. He's fed up with Vista grinding to a crawl (the kids? :), so he likes the "potential" security offered by Ubuntu, but because the computer will be multi-booting Ubuntu (primary) and 2 Vistas (one for him, if he ever needs it again, and the other one for the kids to screw up (again). However, he is concerned about any non-Ubuntu access to the Ubuntu partitions (and also to his Vista partition)... I believe TrueCrypt will do the job for his Vista, but I'd like to know what the best encryption system for Ubuntu is... If TrueCrypt works for Ubuntu, it may be the best option for him, as it would be the same look and feel for both. Ubuntu will be installed with 3 partitions; 1) root 2) home 3) swap.. Will Ubuntu's boot loader clash with TrueCrypt's encrypted partition? PS.. Is encryption a suitable solution?

  • How to fix GRUB on dualboot with Windows7 and Ubuntu?

    - by b_oliv
    I am a relatively recent user of Linux. I had several releases of Ubuntu installed on my laptop working in dual-boot and never had any issues. Recently, I installed openSUSE because I thought it would be necessary for an assignment at my university. It turns out it wasn't so I returned to Ubuntu and decided to burn the new .iso to a CD and install it. The problem is that during installation process I almost for sure messed up with the partitions and now, whenever I tried to load Windows 7, it will tells me that a required device is inaccessible. So, I reinstalled Ubuntu again and now all I get is that I am redirected to the GRUB menu without any warnings. I tried creating a Windows Recovery Disk but it gives me Unexpected I/O error. I suspect it is because it was downloaded from the Internet and maybe some files weren't there. I tried everything without success, so I decided to ask here, in the hope I can receive some help and also learn how to help others with it in the future. Here it is my boot info summary: http://paste.ubuntu.com/1344990/ Also, I might add, that on the boot-repair advanced options, the box repair Windows boot files is "locked", so I can't check it. EDIT: Apparentely, the box is locked, because, from what I understood after reading the boot-repair information, everything is fine with my windows boot-files... I still need some guidance though

  • Installation on SSD with Windows preinstalled

    - by ebbot
    I bought a laptop with this fancy SSD drive, fancy new UEFI aso. I figured at first Windows out Ubuntu in but after doing 3 DoA on 3 laptops in one day I realized that maybe keeping Windows could come in handy. So dual boot it is. And this is what I've got: Disk 1 - 500 Gb HD 300 Mb Windoze only says "Healthy" don't know what it's for. 600 Mb "Healthy (EFI partition)" 186.30 Gb NTFS "OS (C:)" "Healthy (Boot, Page File, Crash Dump, Primary Partition)" 258.45 Gb NTFS "Data (D:)" "Healthy" 20.00 Gb "Healthy (Recovery Partition)" Disk 2 - 24 Gb SSD 4.00 Gb "Healthy (OEM Partition)" 18.36 Gb "Healthy (Primary Partition)" So I'm not sure what the first partition on each drive does (the 300 Gb on the HD and the OEM Partition on the SSD. Nor do I know what Data (D:). I think the 2nd partition on the SSD is for some speedup of Windoze. I'm debating if I should shrink the OS (C:) drive to around 120 GB or so. Clear the Data (D:) and also use the whole SSD for Ubuntu. That would leave me 24 Gb for e.g. / on the SSD and some 320 Gb on the HD for /home and swap. Is this a reasonable setup? Do I need to configure fstab for the SSD differently to a HD?

  • Will Ubuntu Live CD move MFT to resize NTFS volumes?

    - by irwazr
    I have a feeling some will consider this a duplicate, but please hear me out. I've been reading tons of questions and threads around this but have never really found an answer for this specifically. I want to shrink my NTFS partition to make room for a Ubuntu install, so I can dual boot them. However when shrinking the NTFS volume in Windows disk management, it will only go so far as the MFT is sitting near the end of the volume. I've read plenty of posts about why it does this, and how difficult/dangerous it is to move the MFT etc. I've also read that Perfect Disk can apparently do it under it's trial period, but I remain cautious to try this method. I was wondering however if the disk partitioning utility included in the Ubuntu install wizard handles the moving of the MFT when dragging the partition boundaries. It all seems too simple that you simply tell it the new size you want it to be. Would it tell me if it couldn't resize by the amount you requested if the MFT was an issue, or move it for you if it were able. I'm concerned it might corrupt the MFT and the volume, even though I doubt the install wizard would be so daft. So what exactly is the deal with the partition resizing tool in the Ubuntu install wizard? Will it safely resize my NTFS volume despite the location of my MFT? Thanks in advance.

  • Cannot connect to Internet via Wifi

    - by lvogel
    I have a laptop that's currently configured as a dual-boot. The problem: I cannot connect to the Internet in the home wireless network through Ubuntu in the apartment where I currently live. The strange part: I can connect to it just fine through Windows (as right now), and I can use the Internet through Ubuntu on this computer with all the other wireless networks I have tried. The problem is only with this particular combination. The only possible explanations I can think of are either that this network is WPS, or that it's a driver problem--Vodafone router. The router 'sees' the computer--and it says it's connected; however, I keep getting prompted for a password, and I enter the key that works with Windows, but in Ubuntu it just keeps asking for it repeatedly, and I can't access the Internet. I don't have an ethernet cable at the moment, but if someone would be so kind as to ask me questions I will gladly answer, and if you have suggestions, I will do them--the only thing is, I am subletting this apartment from someone who is away on vacation, so I don't want to screw with the router settings unless I know what I'm doing! - I do not have Wicd - Yes, I have the router's information (key works in Windows) - Feedback of lshw says that the wireless card is Ultimate N Wifi Link 5300, vendor: Intel Corporation, physical id: 0 ,etc. The first two commands I was told to try work OK, but when I typed sudo ifconfig wlan0 essid ..... I got back 'essid: Unknown host' Would my question be better on the Ubuntu forums than here on AU?

  • Can I install Ubuntu 13.10 without the internet?

    - by user1526570
    I'm new to Ubuntu and Linux in general. I'm currently out of town and the dorm I am living in has terrible internet connection. It won't be another 2-3 weeks before I can go home and have proper internet connection. So my question is whether or not I can install Ubuntu 13.10 in my laptop without the internet and then do the updates once I go home? Also, I'm attempting to do a dual boot with my Lenovo G505s which was pre-installed with Windows 8. Hopefully I can pull this off. I already did the necessary things (I think and hope so) prior to installation: Disable secure boot Enable legacy and boot UEFI first Create partition Put installer in my pen drive As I am quite new to this, any advice would be of great help. Thanks in advance! EDIT: I tried yesterday. The installation asked me to connect to the internet, so I used my crappy dorm internet. When it reached the downloading/installtion of Ubuntu One, it just stopped and went on forever. So I had to stop it.

  • Force10 layer 3 switches

    We've been running Cisco and dell layer 3 switches. The former are expensive and reliable, the latter a lot cheaper and fraught with issues. Anyone has positive experience with the core Force10 switches (and edge switches as well)?

  • Layer 3 Protocol only in wireshark

    - by javardo
    I have a simple question: is there any way in wireshark to avoid resolution of protocol besides the protocol of layer 3 ? For example, in the column protocol, instead of showing http, I want it to show TCP or it's value (6). I can see in menu analyse / enabled protocols we can disable one by one, but for very big traces with lots of differente protocols like "eDonkey" "QUAKE" etc, it's costs a lot of time...

  • How to build a good service layer in ASP.NET?

    - by Swippen
    I have looked through some questions, technologies for building a good service layer but I have some questions regarding this that I need help with. First some information of what I have for requirements. We currently have a number of web applications that talk to each other in a spiderweb looking way (all talking to each other in a confusing way via webservices and database data). We want to change this so that all applications go through a service layer where we can work more with cache and encapsulate common functionality and more. We want this layer to also have a Web API so that 3rd party clients can consume information from the service. The problem I see is that if we build the service layer with say MVC4 Web API don't we need to communicate between the application using the webAPI meaning we have to construct URLs and consume JSON/Xml. That does not sound too effective. I assume a better method would be working with entities and WCF to communicate between the application but then we might loose the Web API magic? So the question is if there is a way to consume a service layer as both a Web API (JSON/XML) and as a more backend service layer with entities. If we are forced to use 2 different service layers we might have to duplicate some functionality and other bad things. Hope the question is clear enough and please ask if you need any more information.

  • Cannot boot from K/Ubuntu install disk on my UEFI system

    - by user93241
    I just got a new system and have been trying to get it set up w/ Win7 & Kubuntu dual-boot, but I've got a major problem. The BIOS of my motherboard (an Asus Crosshair 990FX) is strictly UEFI -- there is no legacy support mode available. I've been reading up on how to get Kubuntu installed in UEFI mode but no matter what I try I cannot seem to even boot into my install CD/USB key properly. I can get as far as the selection screen ("Try Kubuntu", "Install Kubuntu"...) but this screen starts off not appearing correctly. If I try moving the cursor around it sometimes seems to correct itself and show me my choices. But once I select "Try Kubuntu" it starts loading, the screen goes black and then proceeds to flicker -- about once every 5-10 seconds or so. This continues indefinitely. I've tried this with both Kubuntu & Ubuntu installation media, even the AMD64+Mac Ubuntu variety that is supposed to be a lot more flexible w.r.t. UEFI. The only hint I've had that the system might have booted correctly is a little drum sound that plays when booting from the Ubuntu install disk. Well, that and the fact that when I hit my system's power button it seems to shut down correctly, even ejecting the CD at the end. This might be a video driver issue; my system has two nVidia 550's, one of which is attached to my primary monitor. (The secondary isn't hooked up yet.) I'll keep looking over similar questions but any advice would be greatly appreciated. UPDATE: I've tried booting into my 12.04 install CD twice now, each time using two different options supplied by my BIOS. One seemed to offer the ability to boot into my CD under UEFI mode -- this didn't even produce the initial boot menu. The other method offers the ability to boot into my CD NOT under UEFI mode. This DOES produce the boot menu, but after this point it seems I still cannot get to a proper video mode to see what's going on.

  • Multiple Problems Installing 12.04, now can't use Windows

    - by user87997
    First I tried using the 32-bit wubi.exe installer from the main Ubuntu website. It worked fine, dual booted with Windows 7 and all. I tried installing several applications and got errors. After searching for a little while for a fix, I found that someone else had solved the problem by uninstalling the 32-bit version and installing 64-bit Ubuntu. Apparently there is no wubi.exe installer for the 64-bit version, so I used LinuxLive to put the iso file onto a USB drive. I changed my the boot order in BIOS to check the USB first. It did, and I got into the Ubuntu installer just fine. Everything was working fine, but then I got an error that GRUB could not be installed. I chose "install manually later" or something like that. Immediately, the installer said it was done and ready for a reboot. At this point, my USB is still in the computer. The computer reboots...and it's back at the installer for the USB. I look up what's going on here, and someone says in a thread they solved it by selecting "Try Ubuntu" then installing it via a shortcut on the desktop. I assumed that Ubuntu simply hadn't installed and it would be safe to try again, so I did. It finished installing, this time I chose a different partition that wasn't being used. The thread also said to reinstall grub to the mounted drive, so I did that. Next I took out my USB and rebooted. I get stuck on the GRUB GNU loader, v.1.99 or something I believe it says at the top. I can't do anything, and it doesn't detect Windows 7 OR Ubuntu. When I check partitions, I have two 43 GB partitions that both have the same files in them (I'm assuming those are the two Ubuntu installations), and can only run Ubuntu off of my USB-- and can't run Windows 7 at all, however from within Ubuntu the windows 7 filesystem and files can still be seen. I have no idea what to do now. I used Ubuntu in the past (9.xx) and never had these sorts of problems! Please help. And sorry for the wall of text.

  • Dual-headed graphics card choice: DVI & VGA with 512MB _or_ DVI & DVI with 256MB

    - by TimH
    Which would you choose? Some more detail: I can choose between: A dual-headed card with both heads DVI but only 256MB of memory A dual-headed card with one VGA and one DVI, with 512MB of memory. Both monitors are 1600x1200 I'll be doing mostly business app development on the computer. No gameplay or advanced graphics work. It's running Win7 and is a quad-core i5. I'm thinking of going with 256MB one, just so both displays are DVI and I don't have to shift between sharp & blurry when I look from one screen to the other. But I'm not sure if the additional RAM would be a huge boon for some reason (Win7 GPU acceleration, for example? But with a quad-core, who cares?).

  • Dual boot - disk partition issues basic vs dynamic disk

    - by dboyd68
    I have a lenovo X1 that I am looking to dual boot windows and ubuntu on. I am having an issue. The disk came with 4 partitions SYSTEM_DRV, Windows C:, Lenovov Recovery, Hibernate Partition I have a SSD (250 gb) I have shrunk Windows C: so that I have 100gb of unallocated space. My plan was to install ubuntu on that. But when I try to create a new partition to install ubuntu on. Windows is saying I have to convert to a dynamic disk. I don't really understand the difference between Dyanimc and Basic disk but a quick search I am assuming I dont want to do this as I boot from this disk? Any suggestions on what I can do to dual boot? Thanks

  • What is meant by the terms CPU, Core, Die and Package?

    - by lovesh
    Now this might sound like too many previous questions, but I am really confused about these terms. I was trying to understand how "dual core" is different from "Core 2 Duo", and I came across some answers. For example, this answer states: Core 2 Duo has two cores inside a single physical package and dual core is 2 cpu in a package 2 cpu's in a die = 2 cpu's made together 2 cpu's in package = 2 cpu's on small board or linked in some way Now, is a core different from a CPU? What I understand is there is something that does all the heavy computation, decision making, math and other stuff (aka "processing") is called a CPU. Now what is a Core? And what is a processor when somebody says he has got a Core 2 Duo? And in this context what is a Package and what is a Die? I still don't understand the difference between Core 2 Duo and Dual Core. And can somebody explain hyper-threading (symmetric multi-threading) too if they are super generous?

    Hi all, Today I have installed Centos 5.4 with dual boot with Vista. Everything was fine, but after testing Centos 5.4, when I tried to load Vista, it did not load. After selecting vista from grub menu, it shows the following message: rootnoverify (hd0, 1) chainloader +1 No bootmgr found I googled and try to fix the boot but failed, Then I restart my machine, boot with vista cd and in rescue option, restore my bootmgr by typing bootrec /fixmbr What happened after that, I can load at vista now, but no grub menu shows :P It seems the Centos went totally invisible.

  • Will I be abled to access 2nd HDD from dual-boot

    - by Ruben
    I'm planning to have a dual-boot on my computer. I have 2 physical hard drives, one 500GB and one 2TB. What I want to do, is have a dual-boot setup (2 partitions, both 50 GB) for Windows 8 and Windows 7. But will I be able to access the 3rd partition on the disk, or the other disk from both OSs? In this case, it would be really useful to access files and install programs, because I could use them on both OSs, as long as I have the same registry keys.

  • Windows 7 dual monitor setup: Wallpaper alignment

    - by Tomalak
    I have the following dual-screen set up on my Windows 7 PC: [2][1], that means my secondary monitor is on the right side of my primary monitor. Now I have a dual-screen wallpaper that should stretch across the monitors. I have set it to "Tile" mode. Problem: The wallpaper invariably starts at [1] (left edge of the image being on the left edge of [1]), and then continues on [2]. It basically splits the wrong way, producing a rather awkward look. How can I make the wallpaper appear correctly (i.e. left edge of the image being on the left edge of [2])?

  • Ubuntu dual boot and grub error 18

    - by srboisvert
    I've attempted to install 9.04 on an older toshiba laptop with a new 300GB drive and am getting the dreaded Grub error 18 that indicates that grub is looking beyond the bios readable area of the HD and failing. I just let ubuntu roll with its default selections when installing and ended up with this: Drive layout /dev/sda1 -ntfs 128GB -boot /dev/sda2 -extended 170GB -lba /dev/sda5 -ntfs 167.59GB /dev/sda6 -ext3 2.33GB /dev/sda7 -linux-swap 172MB I'd like make the system dual bootable without having to reinstall windows (real pain since I would have to go through an obstructionist IT dept). I know I can make windows bootable with a rescue disk and fixmbr but is there something I can do to make it dual bootable using the ubuntu livecd? Alternately, what should I have done at the partition stage of ubuntu installation to avoid this?
