• How to dualboot Ubuntu on Asus Zenbook UX32VD?

  - by Tom

  I have just purchased a Asus Zenbook UX32VD and it will arrive on Monday. However, I do not know how to dualboot Ubuntu on this, because of two reasons: It is a hybrid 500GB HDD + 30GB SSD, therefore the OS has to be smart enough to use the SSD to speed things up. But what does this mean when selecting partitions etc. while installing Ubuntu next to Windows 7? It does not have an optical drive; windows 7 is preinstalled. What steps should I follow to dualboot Ubuntu on this correctly? Will this cope with the HDD+SSD hybrid technology?

• Windows 8 + Ubuntu dualboot problem - ubuntu does not load after windows updates

  - by Michal Biros

  I have installed Windows 8 64-bit and Ubuntu 14.04 64-bit in dualboot with EFI mode. Everything worked great. I could run Ubuntu or Windows without any problems. Only one little issue was that Windows locked NTFS partitions when I shut it down. When I clicked on restart button in Windows and started Ubuntu, partitions mounted successfully. But today ... I opened windows and downloaded all available updates. When I wanted to come back to Ubuntu I noticed that grub did not count down seconds to automatic start. After choosing Ubuntu option manually, the OS did not load. Just black screen with white underscore in the upper left corner. Windows is accessible always without such issues. Last time I solved it by reinstalling ubuntu but I dont want to do it each time windows downloads some updates. Have you ever meet such problem, or do you know how to solve it? EDIT Ubuntu boots, but it won't start. It ends on loading screen.

• Grub2 -- Dualboot Ubuntu LTS 12.04 and Windows 7 -- Detects two Windows 7 (loader) entries

  - by DarkIron112

  this is the first question I have ever asked the Ubuntu Community. :D I'm fairly new to Ubuntu, but I understand the basics and know how to navigate the Terminal. I also know how to ask for/research my problems before asking for/ help. I have scoured the internet high and low and learned much of how Grub2 works. But nothing has helped me to solve my problem. My problem is this: I have a computer that has three hard drives. It previously had Windows XP, but I upgraded to Windows 7. I also installed Ubuntu 12.04 LTS (Precise Pangolin). During my installation of Windows 7, there was a failure and I had to restart the installation. Afterwards, I installed Ubuntu. After some trouble removing all traces of the XP OS (Ubuntu auto-detected it, but not Windows 7) I got the two OSes working flawlessly. Or, almost. When booting up, Grub2 used to display Ubuntu, Ubuntu Recovery Mode, Other Versions of Linux, memtest, followed by "Windows 7 (loader) on /dev/sda1" and "Windows 7 (loader) on /dev/sdb1". I eventually removed Recovery Mode, Other Versions, and Memtest. Now, when I run: sudo update-grub I get this print-out: Generating grub.cfg ... Found linux image: /boot/vmlinuz-3.2.0-26-generic Found initrd image: /boot/initrd.img-3.2.0-26-generic Found Windows 7 (loader) on /dev/sda1 Found Windows 7 (loader) on /dev/sdb1 I would like to remove "Windows 7 (loader) on /dev/sda1", as it is a broken entry that shouldn't exist, and must have been installed during my first Windows 7 attempt. I cannot find a Windows 7 entry in /etc/grub.d... And I don't know where to look. Here is a layout of my hard drives: /dev/sda1/ (1.82 TiB), NTFS ("Media") /dev/sdb1/ (100 Mib), NTFS ("System Reserved") /dev/sdb2/ (149 GiB), NTFS ("Windows 7") /dev/sdb3/ (149 GiB), Extended (" ") /dev/sdb4/ (145 GiB), ext4 (" ") /dev/sdb5/ (4 GiB), linux-swap (" ") /dev/sdc1/ (488.28 GiB), NTFS ("Downloads") /dev/sdc2/ (488.28 GiB), NTFS ("AltMedia") /dev/sdc3/ (886.45 GiB), NTFS ("Personal") unallocated (2.09 MiB), unallocated What I think has happened: Windows 7 installed first and badly. I installed it again. First, there was Windows XP to guide where the bootloader went to so it was put on /dev/sdb1/. But, the second time no such guide existed so the machine put another bootloader on /dev/sda1/. sda1, by the way, is the only partition on a 2TB drive. No boot record partition appears to exist according to gedit. I'm not sure where Grub2 is getting this information from. But, there it is. Is there anything somebody can do to help me? Or, is there any more information I should add? Thank you, community!

• Dualboot harddisk encryption

  - by amfcosta

  I have a system with both Ubuntu 11.10 and Windows 7 and I want to encrypt the whole harddisk or at least some of my partitions. My partition table is something like this (the ones marked with * are the ones that need to be encrypted): Windows boot reserved partition *Windows system partition (ntfs) *Windows data partition (ntfs) Ubuntu root partition (ext4) *Ubuntu home partition (ext4) Ubuntu swap As I said I don't need to encrypt the whole disk. What is the best way to accomplish this? Maybe something (TrueCrypt?) where I enter the password before the system boots so that it decrypts the whole hdd? Or maybe individual encryption using Windows-only encryption (for Windows partitions) and Ubuntu home encryption (well, for Ubuntu home partition)? By the way, I almost always use Ubuntu, so it would be nice if I could continue to boot Ubuntu by default but have an option to boot Windows too (like in grub). EDIT: I was thinking of doing this: encrypting ubuntu home with eCryptfs (I think this is used to encrypt home when selected during installation). Encrypting Windows partitions with TrueCrypt. Still having Grub as a bootloader, when I choose ubuntu everything goes as normal (home is decrypted when login in). When I choose windows the TrueCrypt password prompt shows and windows boots.

• Dualboot Asus n56v (ubuntu / win 7 x64) - ubuntu doesn't detect partition table made by windows

  - by user76439

  I have an Asus n56v and I've got troubles installing Ubuntu 12.04 x64. I already have installed Windows 7 x64! The hard drive is: Hitachi HTS547575A9E384 My problem: The installation program doesn't recognize the already existing partitions and is offering only options where there are partitions. Can someone help me out? Is this an ACPI/IDE conflict, missing driver or conflict with Windows 7? (I'm not an expert on Linux, only working sometimes with it.) I now tried out some options concerning EFI with a GTP-table. Everything worked but I wasn't able to fix a dual boot (Windows boot loader) nor with GRUB2. The laptop is still having a BIOS, but is able to boot DVDs/CDs in EFI-mode. Now I try to avoid EFI and GTP using the old windows MBR style. I reinstalled Windows, so far no problem. When I want to try to install Ubuntu, it doesn't detect the already existing partition table. It is just showing me an empty space for the whole disk. Other threads like Ubuntu 12.04 does not see windows already install on my computer (dual installation) don't help me out. os-prober shows me a correct result. I don't know how to deal with gdisk as shown in Installer doesn't detect existing partition table/windows 7 partition. I have 750GB for the whole disk. I'm using: 90GB for Windows reserved partition + system partition, 500GB for data and the rest should be for SWAP and linux-system. How can I make Ubuntu detect the partition table?

• Dualboot (Win 8 / Ubuntu 13) is stuck at 'switching to clocksource'

  - by Daniel Puscht

  for days I have been crawling the web for solutions to my problem, but couln't find any. Here it is: I got a new Laptop (ASUS Vivobook S200E) with Win 8 OEM preinstalled. I wanted to create a dual-boot system with Ubuntu 13 next to it. I read about UEFI and that I have to turn of Secure Boot and use the existing EFI partition as bootloader for Ubuntu. So I did. I also ran boot-repair reinstalling the GRUB. The result is when I start the computer I get into the boot menu. So far, so good. When I pick Win everthing is fine. But when I choose Ubuntu (recovery) the system starts, but gets stuck at the line '[1.806366] Switching to clocksource tsc'. I already tried other versions of Ubuntu (12.04.2, 12.10). I played with boot-repair (using the recommended fix, setting everything manually). But nothing works. It's always the same issue. I read that it could be a problem concerning graphic drivers, but this I can hardly believe. If this is any help, boot-repair gave me this link to post in fora. http://paste.ubuntu.com/5810391/ Thanks for any help in advance

• Error 15 after manually installing Ubuntu 12.04 dualboot windows 7

  - by indraisme

  (this post contains as the same as my preceding post on Grub rescue problem after installing Ubuntu 12.04 LTS since I've post it on the wrong place) Thanks God I found this page. I'm a newby from Indonesia, and I have a laptop with 2 OSes (7 and Precise) installed. I have installed Ubuntu 12.04 manually by replacing Blankon 4.0's (an Ubuntu-based Indonesian distro) partition. I made /boot mountpoint and then chose it as the place for bootloading. As the result, I've been experiencing error 15 until now, and I have to boot my laptop from Paragon rescue kit every time I want to use it. Is there any way to solve the problem? Terima kasih (Thanks)

  - by cr8ivecodesmith

  I have a running Windows 7 and installed Precise along with it just this afternoon. I was doing a manual partition configuration. On the part where I get to set what partition to install the bootloader/MBR I chose the Windows partition. Now every time I choose Windows 7 from GRUB, it just reverts back to the GRUB menu. I've been reading around the web as I type this and found this tool 'Bootinfo' to let you see my configuration. Here's the pastebin: Boot Info Any help would do. Thanks!

• DualBoot 32Win & 64Mac from Live USB +Persistance

  - by josephsmendoza

  So I have a 32 bit Live USB with persistance that I use to write code, cause that's just how I roll. I can boot it onto my school computers(32 bit Win) no problem, but obviously not my Mac (2007 iMac, 64 Bit). Currently I use VMWare Fusion 6 Pro and a Plop Linux image to use the usb at home, but I can only get 900mb of ram for my VM. I was hoping to make a Live USB that can boot 32 bit and 64 bit for mac, with a shared persistance file, this way I can use my computer's full 2GB. Also, I'm not allowed edit any part of this Mac. Do Not reply telling me it's impossible. Please only solutions. Thank you, and have a unicorntastic day!

• Dualboot - Windows partition does not work [0xc000000e] + video

  - by Chestnutjam

  Some may claim that this has already been asked, but I don't see MY problem in any of those posts. And if they actually have the same problem as mine, I may not understand what they've been trying to point out, actually. I hope you understand as to why I require a direct answer to the problem I'm having. Here's a video: https://www.youtube.com/watch?v=lyu_BsUTk5Q Some information that may help: This is a Lenovo laptop which came with Windows 8. I installed Ubuntu 14.04 along my Windows using a USB stick. It is possible to access my Windows (8.1) files from the folder page. I took off the Windows sticker, so I cannot get a Windows CD or anything from the support guys. I would delete my Windows partition then, but it's also tangled in this geeky mystery. Thank you in advance!

• Finding Bluetooth link key in Windows 7, to double pair a device on dualboot computer

  - by Ilari Kajaste

  How can I dig up the Bluetooth link key for a paired device in Windows 7? Is this something that is dependent on the Bluetooth stack I'm using (Toshiba), or is there a generic place to store these in Windows 7? Note: I'm not talking about the six-digit code usually typed by the user during pairing - that is worthless since it's discarded after pairing process. What I mean is the 128-bit link key that the devices exchange during pairing, and use thereafter to encrypt all their Bluetooth traffic. Background: I dualboot Windows 7 / Ubuntu on my laptop, and I would like to have my phone paired to both OS's. Since the dualbooting computer has only one Bluetooth adapter and thus only one Bluetooth address, I cannot do two pairings to the phone, since on the second pairing (Windows) the phone just replaces the previous pairing (Linux) to the same Bluetooth address. A thread on Ubuntu forums pointed me to what I have to do - pair first on Linux, then on Windows, and then replace the link key on Linux side with the one Windows negotiated. I can find the Linux side pairing key from /var/lib/Bluetooth/[BD_ADDR]/linkkeys - no problems there. However, on Windows side I can't find the key. According to the forum post, on Windows side the key should be in SYSTEM\ControlSet002\services\BTHPORT\Parameters\Keys\[BD_ADDR] but while that registry key does exist, it has no subkeys. (And a similar registry path in ControlSet001 didn't have any subkeys either.) One thing I've been instructed to do is to capture all events during pairing with Sysinternals Process Monitor. I did this, but I haven't been able to find any useful information from the captured events, not even by exporting the data to a huge XML and grepping that with the BD_ADDRs (with or without colons). So how could I find the link key for a paired device in Windows 7? Some reference information: Wikipedia: Bluetooth, Security Now: Bluetooth security

• Setting up a dualboot by installing cloned partitions using clonezilla

  - by Nimjox

  I'm trying to setup a dual boot system where I have Windows 7 and Linux Mint. Here's the kicker both are partitions I've saved using Clonzezilla from different places and to make matters worse Linux Mint is formated as a LVM. I need both of these images specifically as windows is a corporate image that I must use and the other is a development image that took me a week to setup. I've gotten it almost all working but my issue is that I can't get clonezilla to not mess up the partition table of Windows when installing Mint or vise-vera. I can use the (-k1 option) which doens't copy the partition table but then I have a unusable partition when it clones and I'm not sure how to fix the partition table. Here's what I'm doing: Using Gparted to make partitions sda1 40GB ntfs (windows), sda2 extended 70GB, sda5 lvm2 pv 69.99 GB (Linux), sda3 500MB (GRUB) Clonezilla windows image into sda1 partition (keeping partition table) Clonezilla linux image into sda5 partition (not recreating partition table) After all that I can boot into windows using the default MBR. I can use rescue-repair cd to reinstall GRUB which will see Windows 7 but I can't get it to see the Linux OS. I'm thinking its because of the sda5 partition but I'm not sure any ideas on what I could do to get this working or where I might be going wrong. If there is any additional detail you need please let me know and I'll edit as this is a lot.

• Divide bootloader from dualboot with Windows 7 and Windows XP

  - by manwithproblem

  My problem is the following: I have a dual boot running on my pc. I installed a programme called "Keriver", it automatically installs GRUB, too. When I start my PC, the first thing you see is GRUB. You can choose between "Boot normal" "Take snapshot with Keriver" "Boot Windows" If you select "Windows" or "Boot normal" it calls the Windows 7 Bootloader and it again shows a menu, where you can choose between XP and Win 7. Unfortunately for me, Microsoft does this "mixing bootloaders into one" automatically. I don't know how to change that now, how to separate them. I'd like to start everything directly from the GRUB menu. The bootloader is stored on hd(0,1). I tried to boot from hd(0,0) and hd(0,2) as well, but it didnt work. Can anyone help me please?

• Windows 7 / Ubuntu Dualboot GRUB Problem.

  - by Tek

  I'd like to first say ahead of time that I'm running a RAID-0 Setup. 1.First of all, I'm glad Ubuntu 9.10 installed flawlessly and detected my RAID-0 setup just fine. The issue I'm having now is that I already had Windows 7 installed and made a small 12GB partition for Linux/Swap. I grabbed EasyBCD 2.0 to edit the W7 bootloader and configured it to use dual boot Grub2 because before it didn't even show the option for Ubuntu. The bootloader points to a file made in the windows directory made by EasyBCD called "C:\NST\AutoNeoGrub0.mbr" which is what I'm guessing grub is booting from. After that I got the option for booting Ubuntu. The problem is that it's sending me to the Grub prompt (probably because it's pointing to \NST|AutoNeoGrub0.mbr?), at first I didn't know what to do but I researched and have to type grub commands to manually boot into Ubuntu Linux. Ex: grubroot (hd0,4) grubkernel /boot/vmlinuz-2.6... root=/dev/disk/by-uuid/24624-2424... grubinitrd boot/initrd.img-2.6... grubboot After all that Ubuntu boots just fine, but how do I fix it permanently? Do I need to edit the bootloader manually (since Easy BCD "autoconfigures")? Some insight on this would rock! Also, it sucks to type the actual uuid since it's REALLY long. I tried getting the name of the drive via fdisk -l but since it's raid 0 I'm guessing I can't do that. How can I get a shorter name of the drive? like /dev/sda, /dev/sdb etc? I've also tried to update to the latest GRUB and I got this: Creating config file /etc/default/grub with new version Generating core.img error: cannot seek /dev/sdc' error: cannot seek/dev/sdc' grub-probe: error: no mapping exists for nvidia_dbedfcca5' Auto-detection of a filesystem module failed.

• Linux/OS X dualboot on a Macbook Pro with RAID

I currently have OS X installed on a RAID 0 on two 160GB Intel SSDs and I'd like to create a new partition for Gentoo alongside OS X without losing the RAID setup but, from what I read on the net, Apple's software RAID is poorly (read "not at all") supported: BootCamp refuses to create a windows partition on a RAID volume rEFIt is not able to boot an OS from a software RAID even Apple's recovery partition for Lion can't be created on a RAID volume Is there a way to dual boot my Macbook while keeping the RAID solution?

• Unable to boot from LiveCD/USB and even Super Grub Disk!

  - by Reuben L.

  Hi all, I'm in a fix. Basically this morning, I decided to format my Win7 as it was getting really slow and I did so with no problems. I also have a Linux Mint OS on dual boot. Since I was springcleaning my windows partition, I decided it was a good idea to do the same to my linux partition. I downloaded the latest version of Linux Mint (Julia) and burned the LiveCD. Now here is where the problem lies, when I restarted Windows and chose to boot from the LiveCD, it didn't work. No joke. There was just a little underscore blinking for a long time before it went back to GRUB which prompted me to select an OS to boot. However, when I went into my old Linux Mint OS and restarted the machine, the LiveCD worked... to a certain extent. It would load and look as though it was ready to install Linux Mint 10 but the moment it got to the option screen, the whole screen turned into a checkered and jumbled mess. At this point I thought it was the LiveCD or the .iso file. I had an Ubuntu LiveUSB for recovery purposes and I tried that. The exact same thing happened. Can't boot the LiveUSB if I restarted from Windows, but works when I reboot from Linux. BUT still the same checkered screen that doesnt respond. Did a bit of googling and reckoned it might be something wrong with my GRUB. Did some updating and didnt make a difference. Then I tried the Super Grub Disk and STUPIDLY uninstalled GRUB. (Note that booting to SGD had the exact same problem - can't be done if I rebooted from Windows). Now I can't access my Linux Mint 9 cos the the bootup screen (mbr) only has Windows 7 as an option. Remember me mentioning that I can't boot from any CD/USB/recovery CD when I reboot from Windows? And now that I can't access Linux, there's no way for me to do any form of recovery! I've tried using the command prompt utility at startup recovery but to no avail. Anyone can help me with this?

• **Simplest** way to dual boot Linux on a Vista laptop

  - by user20285

  I have a 64bit Vista laptop with no cd drive (and no intention of buying one). What is the simplest way (if any) for me to dual boot Linux (I don't care what version as long as it's not too old...and will run Ruby 1.8.7 or greater)? I'd prefer anything with an installer. I've been programming on Windows for a little over 1.5 years and would like the option of using Linux. I'm not a moron, but the I'm legitimately scared of messing up my computer. I speak the language of Rails, not of OS tweaks. Thanks!

• Dualboot 12.04/windows 7 After installation from USB reboot straight to Windows with no option to select ubuntu and no boot loader

  - by Alkatraz

  windows 7 home premium intel i5 2500k CPU ASUSP8Z68-V PRO Motherboard GeForce GTX 570 GPU corsair 120Gb SSD (windows 7 os) WD 1tb HDD I select the USB drive in the BIOS and boot to it and choose install. i select to manually configure partitions, partition the 200gb of unallocated space on my 1Tb HDD into 16Gb swap file 30Gb / extf4 and 154Gb /home extf4. I make sure that the boot loader is installed to corsair 120Gb SSD (where the windows boot is) and installation goes smoothly. When i reboot after install it runs through bios strait into windows. I have tried upwards of a dozen times and i have also tried with linuxmint. I have also redownloaded the ISO and used two different programs to create the live usb. the installation seems to go well as i can see the partitions i have created in the windows device manager after install http://imgur.com/Wp0V1 I currently run lubuntu on my laptop but it is not a dual boot. i'm assuming this is a boot loader issue and i am assuming that inside those partitioned files in my screenshot there is a working OS of ubuntu 12.04 i just have no way of getting to it.

• 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

  I'm using GRUB2 to dualboot Ubuntu and Windows 7. I installed Windows 7 some days ago and rewrote GRUB2 to cope with the dualboot. Everything went fine till yesterday - I could boot into both OS. Since this morning my laptop restarts every time I choose Windows 7 from the menu. Ubuntu is still working. As I tried to mount the partition with Windows 7 on Ubuntu it gave me return code 2, so this isn't working as well. I tried to reinstall GRUB2 to the MBR but it didn't help. I also tried to repair Windows 7 boot with it's install DVD, while trying so it showed me the following error: "Status: 0xc000000f Info: Boot selection failed because a required device is inaccessible." Tanks in advance
