Ubuntu Installation :: Windows XP Fails To Boot From GRUB?

Aug 24, 2010

I have installed Ubuntu 10.04 LTS-the Lucid Lynx on top of a Windows XP installation. The Windows partition started before I did this. Now, all I get is a flashing cursor when I tell GRUB to start the Windows XP partition.

I have tried reinstalling Ubuntu with no effect. I have tried repairing Windows using a Windows installation disk.

However, I can reach the files in the Windows partition just fine from Ubuntu.

Ubuntu Installation :: Reinstalling Grub Fails After Windows 7?

Jan 15, 2011

I previously had a single 160gb drive with two partitions, dual booted for Ubuntu and XP. I then installed a new SSD drive and put Windows 7 on it and of course I lost grub on the MBR. I have gone through this before so I went ahead and booted the livd CD, installed grub then ran

root (hd0,1)
setup (hd0)

but then got these errors;

Error 22: No such partition
grub> setup (hd0)
setup (hd0)
Checking if "/boot/grub/stage1" exists... yes
Checking if "/boot/grub/stage2" exists... yes

Ubuntu Installation :: Grub Fails To Be Written In Boot Sector / What I Need To Do?

Nov 21, 2010

I am a complete noob at this and I need a hand. I was about to throw my computer out of the window when I decided to throw the windows out of the computer so to speak. So, I downloaded Ubuntu 10.10 and tried to install. I had a grub rescue after the installation (file system unknown), which I have seen discussed here. Being the noob that I am I decided to try 10.04 because it said it had full support. With this install I get a similar error during installation: grub cannot be installed in boot sector.

So, basically there is an issue with grub and the boot sector. I checked in my BIOS options to see if there was an option that prevented the writing of a boot sector or something, but I have not been able something like that. So, I am wondering if it is possible that Ubuntu does not really erase/format the selected disks or something, leaving any difficulty there.

Does anybody know? Or better yet: what exactly do I need to do a manual grub install?

Ubuntu Installation :: 10.04.1 Install Fails To Boot -> Error: Out Of Disk, Grub Rescue

Jul 13, 2011

Downloaded Ubuntu 10.04.1 Desktop AMD64, tried to install it to a cleand HDD using the whole HDD, i.e. gave it permission to use the whole HDD. Installation process appeared to run OK but when it came to the restart it just fired up the message

error: out of disk
grub rescue>

I've searched this forum and found numerous references to these error messages but cannot make head nor tail of the diagnostic suggestions. Apart from anything else they suggest strings of command lines which I don't understand and can't enter anyway since they don't correspond to my keyboard layout (if I hit > or ) something completely different appears on the screen). Is there someone here who can provide a step-by-step solution in lay language ? Or is there such a thing as a bootable file which can be downloaded and inserted into my CD drive to correct this problem ?

Ubuntu Installation :: Windows 7 Boot Engages But Fails?

May 8, 2010

post another windows 7 / ubuntu studio 10.04 dual boot thread, but I've tried researching this all evening and I am still not getting anywhere...

-- installed windows 7 on my HP g61
-- defragged using perfectdisk 11
-- used windows 7 volume shrink to get windows partition to 65 GB
-- created an NTFS volume in the new 220 GB partition with windows (Ubuntu studio's partitioner would not recognize the space unless I did this first)
-- ran ubuntu studio 10.04 installer
-- deleted the 220 GB partition and the installer automatically created a new ext4 partition with a swap partition.

Ubuntu Installation :: Add Windows 7 To My Grub Menu Or To Even Be Able To Boot To Windows 7?

Mar 5, 2011

how to be able to add windows 7 to my grub menu or to even be able to boot to windows 7. I am currently unable to do it and my system just automatically goes straight to ubuntu. I've tried holding down SHIFT during startup and all that appears in my list is ubuntu entries and a memtest entry. My windows 7 files are still intact because I can see the drive through ubuntu and see all my files. I am trying to have Windows 7 on one hard disk that is 640GB and ubuntu on a second hard disk that is 160GB

General :: Grub Boot Loader Installation In Dual Boot Machine After Windows 7 Installation?

Mar 23, 2010

I had a dual boot machine with fedora 12 and windows vista and I could use grub boot-loader to switch between two. Few days ago windows got corrupt and I have to reinstall it. I put windows 7 now and as usual it erased grub. So to reinstall I put the fedora 12 installation CD on and followed some usual setup steps. When I got the command line I issued the command "grub-install /dev/sda" (sda not hda because It showed bunch of sda, sda1..) but surprisingly it said grub command not found. I remember doing it before while it worked fine.

Fedora Installation :: Dual Boot With Xp - Grub Can't Boot Into Windows?

Jan 10, 2010

I just set up a dual boot on a system with fedora 12 and XP. XP in on one hard drive (sda) and Fedora on a second hard drive (sdb).

I installed grub on the Fedora disk so as to not touch the windows disk at all.

Prior to installation, in the bios, I set the Fedora disk (sdb) first in the boot sequence, and then XP (sda) so that the grub loader would boot up by default. (If I set the windows drive first then the system bypasses grub and loads straight into windows.)

My system can now boot up into Fedora fine, but if I select windows from the grub loader menu I just get a blinking cursor - windows will not boot.What do I have to do so that grub can boot into XP?

Ubuntu Installation :: Can't Get GRUB To Boot Windows XP On USB HDD

Dec 29, 2010

I had Windows XP installed on my PC then bought a new HDD, installed Windows 7 & Ubuntu 10.10 in dual boot, later I added the Windows XP HDD as an external USB then typed "update-grub".

At boot up the drive appears at the bottom of the GRUB menu but when I select Windows XP it gets as far as the XP splash screen, after a few seconds there is a flash of blue screen with some writing on it then the PC re-boots. Here is grub.cfg:

# It is automatically generated by grub-mkconfig using templates

Ubuntu Installation :: Grub And Other Boot Systems (Windows)

May 1, 2010

I have Win7 and ubuntu installed on the same PC. Win7 was installed first, after I installed GRUB from Ubuntu, Win7 is not listed as a second option to boot. FYI, On the same PC I had Win7 and Debian (before changing from Debian to Ubuntu) and GRUB from Debian was showing Win7 as second option for boot. Ubuntu was installed on the same partitions as Debian. (For Win7 I have 2 partitions one 100M-system reserved and one 30G; both on NTFS). I have:

Ubuntu Installation :: Boot To 10.04 Or Windows XP From Grub Menu?

May 3, 2010

It would be nice to get a sticky thread up for dual boot installation issues. It seems like this is a very common problem with the upgrade from 9.10 to 10.04.

I was finally able to solve my issue dual booting 10.04 and Windows XP Home at this thread.


I had to reinstall Grub2 and run update-grub.

Then I had to run Rescue on my XP disk. Once to the DOS command line I ran the following command:

C:Windows>fixboot c:

I rebooted and now all is well. I can boot to Ubuntu 10.04 or Windows XP from my Grub menu.

Ubuntu Installation :: Can't Boot Windows 7 After Grub Update

Jul 21, 2010

I have been phenomenally unlucky with Ubuntu as seen my my post history and decided to dual boot.

I set it all up with a clean install, when I tried to load Windows from Grub the computer restarted. After much headache I managed to set it up correctly (when it wouldn't load from Grub I booted from the Windows CD and clicked on "Repair computer" and it finally worked).

Now I am having the same problem as before--I think my installed all the updates from Update Manager and it included a grub one. Now I can't load Windows from the grub menu: It goes to the Starting Windows screen and then reboots my computer. If I do it again it gives me an error message and an option to perform "Startup repair". When I try to do Startup Repair, the computer reboots after a few loading screens.

So I tried what worked before and put in my Windows 7 CD, and clicked on Repair Computer. BUT NOW it gives me an error message somewhere along the lines of system restore is not compatible with my installation of Windows, and to insert a compatible recovery CD. This is the ONLY Windows CD I have (legitimate copy).

Over the course of this migration experiment I have installed and reinstalled both operating systems 7-10 times total. I'd rather not do it again. My poor laptop is probably wondering what the heck.

I can't stick with Ubuntu alone because my wireless doesn't work with it, my grad school files are not completely compatible with open source software, and I can't play the games I'd like to. So I must have the option to at least dual boot into Windows.

When selecting Windows it restarts the computer entirely to the Compaq screen, not just to the Grub menu, if that matters.

Ubuntu Installation :: GRUB 2 Does Not Recognize Or Boot Into Windows XP?

Oct 13, 2010

i can't boot up my win XP after installing Ubuntu 10.10.

I decided to replace my Vista partition with Ubuntu 10.10 so i redo my partitions and split the current Vista partition to a swap and root partition and install Ubuntu 10.10

Everything went well and i got Ubuntu up and running. However, i realize that GRUB 2 didn't recognize my existing windows partition. I double-check on grub.cfg and see that the default os_prober didn't recognize my XP partition either.

After search on the internet for a while, i found many similar issue where most are fix when manually adding the entry yourself so i decided to add an entry 11_XP under /ect/grub.d/ for windows XP and confirm that the new entry are added to the update grub.cfg file before restarting

### BEGIN /etc/grub.d/11_XP ###
menuentry "Windows XP" {
set root=(hd0,5)
insmod chain
drivemap -s (hd0)

Ubuntu Installation :: Windows Boot Loader And GRUB ?

Jun 14, 2011

I installed Ubuntu 11.04 64-Bit via Wubi but it seems that when I turn on my machine I first get the Windows Boot Loader, when I select Ubuntu from the list it then goes into GRUB with the option to select Ubuntu or Windows. Is there any way to change this so only GRUB is used?

Ubuntu Installation :: Grub For Dual Boot (with Windows 7 Pro)?

Jul 8, 2011

11.04 installed on free space I had setup but it didn't install Grub2 for a dual boot (with Windows 7 Pro). It may have gotten confused with my disk setup. Drives and their groupings (Windows lingo):

- Windows 7 Pro on C-drive (appears to be sdb2), it is a SSD
- The free space was setup on this SSD and Ubuntu is located on sdb5 (Linux) and sdb6 (swap space).
- Applications stored on D-drive (RAID0 with 2 small SSDs using RST (Intel Rapid Storage Technology).
- data on a RAID card using HDs in RAID0.

Small wonder it got confused, if that is the problem. I have a LiveCD I can use to boot, is that the best? What are the commands to install. Is there a better way?

Ubuntu Installation :: GRUB Removed After Windows 7 Boot

Sep 1, 2011

I'm running Ubuntu 11.04 and Windows 7 on a Dell Inspiron. On boot I get the GRUB menu listing Ubuntu (+ old versions) and Windows 7. However, if I boot Windows 7 all is fine until I reboot. On this next boot GRUB is gone and Windows boots. Ubuntu is still there, I can get into using my live-cd and 'repair' GRUB. After that, on booting GRUB is back and fine (including Windows 7). Does any one have an idea how to fix the booting/GRUB thing more constructive?

Installation :: GRUB On USB Drive - Boot Into Windows

May 6, 2010

I installed Ubuntu on a portable usb drive using a live CD. But now my computer NEEDS the USB plugged in in order to access the GRUB on it so I can boot into Windows from my hard drive. If I boot up my computer without the USB drive plugged in my computer gives me the prompt "Rescue grub" with the ability to type stuff in. I tried to use F12 on startup of my computer in order to tell it to boot using my hard drive (where my Windows 7 is installed) but still no luck.

If the USB drive is plugged in at start up, I get a neat little menu giving me a choice of booting into either Ubuntu, Windows 7, or the memory test. And all of that works fine. Basically, the problem is, I want to boot into Windows without needing that darn USB drive having to be plugged in when I start my computer.

Ubuntu Installation :: Can't Get Grub To Boot Straight Into Either Of The Windows Versions?

Jan 24, 2010

I've recently reinstalled all the os's on my computer, just now I'm going with ubuntu (general use) win xp (for flash, it doesnt play nice with 7 for some reason) and win 7 (for games). Everything is fine, but I can't get grub to boot me straight into either of the windows versions: Each option makes brings me to the windows bootloader, where I can choose between "Windows 7" and "Older version of windows". I want to go directly from grub to xp/7, without that extra menu. How do I get rid of it?

Using ubuntu 9.10. I snooped around and found a script to run that should give some helpful information:

Ubuntu Installation :: Unable To Boot Into Windows After Upgrading Grub

Apr 10, 2010

I upgraded from grub to grub2 recently, and during an update of my system, it ran the update-grub command which prompted a window asking me where to install Grub. Since I didn't know what partition to install it to and the help suggested to install it to all if I was unsure what partition to install it to - I accidentally installed Grub to my Windows partitions (both the regular and the recovery console).

So now, I can't boot into Windows - the computer just hangs after Grub with a blinking cursor and I have to perform a hard reset. Is there any way for me to restore the boot record for the windows partition without having to reinstall windows from the ground up?! I can't use Linux for my webbanking and other important tasks, so (unfortunately) I need Windows back desperately!

Ubuntu Installation :: Error On Update-grub & No Windows Boot?

Oct 23, 2010

With a bit of help from this forum I managed to install 10.04. The solution was to add i915.modeset=1 to the options when booting up from CD.Now I need to do the same in order to boot up from HD. I've opened /etc/default/grub and changed the relevant line to include the above option. But I need to run "update-grub" and it comes back with an error to the effect that it 'can't find a device for / (is /dev mounted?)Also, the boot menu only has ubuntu - no sign of windows in my intended dual-boot. What can I do?

So how do I get grub or Ubuntu load with windows xp boot loader? I tried with Live cd, the sudo grub but then it says command not found. I think its because Ubuntu 11.04 uses grub 2.

Fedora Installation :: Boot Windows Vista From F14 Grub

Jul 2, 2011

I'm new to linux systems and just installed Fedora 14 onto my Windows Vista laptop. I chose the shrink existing system option and then proceeded to install Fedora. The only problem is that when I choose Other in the Grub boot menu my Windows Vista goes straight to the recovery screen and does not boot. I don't want to do a point recovery. Is Vista not running because I shrunk it or because of some configuration that I did not add in the Grub files. How to solve this problem and get Vista running properly from the dual boot menu?

Ubuntu Installation :: Grub Upgrade - With Image #22 And Unable To Boot Windows

May 17, 2010

I recently performed a reinstall of ubuntu after mucking up my partitions, and I am running it dual booted with windows 7.

I recently performed a grub-pc update, but I didn't know what it was asking me to do during the process itself of updating the process.

It asked me at one point where to install grub, and I selected all my partitions because it suggested that if I didn't know. I think that may have damaged my windows section, which was also selection.

I've attached the output for:


Problem symptoms:

1) Weird upgrade error in apt-get
2) Unable to boot windows 7
3) Unable to activate proprietary drivers
4) Perpetually being reminded to restart
