General :: Uninstalling From Windows 7 PC - Grub Error 22
Mar 15, 2010
I installed Backtrack 4 and it is set up as a dual boot with my Windows 7 x64 bit. I want to uninstall Backtrack because I am going to put it on a different computer. The problem is - I can't do it. My laptop is an Asus K61IC, and it doesn't come with an installation CD, because the OS was factory installed. It comes with a recovery wizard instead, which gives me the options to 1) recover to first partition only, 2) recover to entire HD, and 3) recover to entire HD with 2 partitions. Because of Grub and it asking for me to choose what operating system to boot when I start my computer, when I recover Windows 7 to the entire HD and try to boot, it gives me Grub error 22. I need to fix my MBR so that the grub menu is also deleted and all of Backtrack 4 is removed, actually letting me back onto my Windows 7. I need a way to delete the Linux partition, and fix the MBR, but I don't know how to do that because I don't have an installation disk.

I am new to Linux. I have installed RHEL 5.4 on my PC with preloaded Windows XP.
Windows was set as the first boot kernel. So if i do not choose which OS to be loaded it will load Windows by Default.
Today I got an error saying GRub Loading Stage2 read error.

I have a dual boot Vista/ Kubuntu and my vista SP2 has made both my vista and kubuntu unable to boot completely. I've been through many steps to recover vista but no restore point works and such so I am going to use my Toshiba recovery partition to reinstall but what I'm wondering is if after I do that will the grub loader be affected and give me the error 22? The two are on separate partitions and I've been meaning to get rid of Kubuntu from my laptop since I have it on my pc

I've just installed Ubuntu after my windows os became completely infested with trojans and viruses. How do I get rid off windows? I can't get rid off the viruses because I can't install an anitvirus for some reason. It's still there when I start up the computer. I don't think I'm using grub, though I'm not completely sure. Is there a way to verify this? On a similar note, can the trojans and virus affect on windows affect ubuntu?

I got BSOD while attempting to uninstall a program in Win XP, so I tried to reinstall the OS (because the guy who gave me the pc wants a clean-up) but a STOP 0x0000007F (0x00000008, 0x80042000, 0x00000000, 0x00000000) occurs.I tried then to boot Kubuntu 9.04 live cd, and it booted fine, but when I tried an installation it failed too: just crashing...
I tried to change the RAM and the hard drives to no avail.I'm thinking that it's an hardware failure, but can't track it down: what could it be? Video card? Motherboard?
EDIT: I ran 7 successful memtest - not even an error. I have to look at the harddisk ribbons and the motherboard.
EDIT No.2: I tried another harddrive, switching to sata connectors to no avail: the sata harddisk it isn't even recognized...Can it be the video card, or it will be the Motherboard?

When i tried to install windows xp and ubuntu 9.04 together i got an error as GRUB 18. Then i installed only ubuntu 9.04. Now i am planning to have both ubuntu 9.04 and fedora 12 on my system. Is it possible that i'll again get the same error? If yes what are the possible solutions?? and is it advisable to have both fedora and ubuntu in the same system??

I know its not a Linux program but my brother had Linux on his HP DV9000 Laptop, Well he wants to go back to windows XP home edition or what ever, he played around with it and messed something up and when you boot it, it comes up with a GRUB error 22, so I try to boot it with the windows XP CD and when i try to install windows or repair it tells me there is no hard disk... which seems kinda stupid considering your PC needs a hard disk to boot up, so in the BIOS menu i did the hard disk testing and what not and it came back 100%...

error: unknown filesystem grub rescue>
Background: My mother's HP laptop had Ubuntu and Vista on it, Ubuntu my brother's doing. He decided he wanted to take off Ubuntu yesterday (he had forgotten the password), and deleted the partition that it was contained within. The computer now boots to this error.
Inventory: We no longer have the install disk for Windows Vista, he cannot tell me what version he used of Ubuntu, what partition it was on, any of the specs for the machine, or generally any information about the system. All I am aware of is that error on the boot-up screen. I have nothing else to work with.
I would like to remove Grub, and Ubuntu, and leave Windows intact (the request of the owner of the computer), but I have no idea what commands I could use to get rid of either when I can't access Windows, or how to properly remove them if I did access Windows.

I made a slight mistake after editing my partitions with Gparted. I accidentally installed Grub 2 on my Ubuntu partition instead of re-installing it on the MBR.
I've since installed Grub 2 on my MBR, but how do I get the Grub 2 installation off of my Ubuntu partition?

I'm dualbooting Slackware and Gentoo on my homeserver. Some weeks ago I built grub with a slackbuild-script, it was the new version of grub but it did not install properly. Since then I could only boot Slackware but not Gentoo. Today I tried to install grub from the Gentoo-partition (I chrooted to Gentoo). This did not work due to an errormessage of grub that "stage1 could not be read".
Afterwards I tried to install lilo, this failed at first attempt, but the with some warnings lilo executed. When I rebooted after the lilo-install, I had grub again at the bootscreen without the option to boot Gentoo. I decided that I have to clean the mbr of /dev/sda and found a solution with the dd command. Here my
[Code]...
Fortunately I have a second disk /dev/sdb in the server and have now installed the bootloader on the mbr of /dev/sdb. But in the long run I want to change this.

And by blank screen I mean after I pick whatever I want on GRUB. There's NOTHING.I even tried going in recovery mode. But same thing.Right now I'm using an older recovery. The newest thing is completely broken. And the regular one for the Ubuntu version doesn't work either.

I have two hard-drives. The first, C: (sda1) has Windows 7 x64 installed on it. The second hard-drive, D: (sdb1), was partitioned when I installed Ubuntu 10.04 into two separate partitions: NTFS and Ext3.
I wanted to remove the Ext3/Ubuntu partition and reclaim that space (i.e. completely remove Ubuntu). I did NOT install using Wubi. I booted up Win7 x64, went into Disk Management, right-clicked the D: partition corresponding to the Ext3 filesystem (shows up as unrecognized in Disk Management), and opted to delete the volume. I then right-clicked on the NTFS D: partition, and opted to Extend the Volume to reclaim the previously partitioned space.
When I rebooted, I ended up with the following error:
Code:
error: no such device: f81368be-ea53-43d2-b8de-bb52b5ac322c.
grub rescue>
I cannot get beyond this screen. Rebooting always puts me at the grub rescue prompt. I have looked at the HOWTO: Purge and Grub Rescue Prompt threads, but was not able to understand the instructions and am therefore asking for your help. However, I was able to install the boot script as those threads suggest, and here is my results.txt:
Code:
Boot Info Script 0.55 dated February 15th, 2010
============================= Boot Info Summary: ==============================
=> Grub 2 is installed in the MBR of /dev/sda and looks on the same drive in
partition #2 for /boot/grub.

I recently installed Ubuntu 9.10 within Windows Vista to try it out I have since tried to uninstall it but the uninstall fails with a message saying it is unable to find the file it is attempting to delete - sysout=. The process has produced a fairly large text log of the procedure and the error but none of it means anything to me.

I have been using Ubuntu Wubi for a few weeks now and am quite happy with it, and I am not missing Windows 7. This is not my first contact with Linux OS. In fact I have tinkled with Red Hat, SuSe and Fedora quite a few years back but never pursued them seriously as I found them difficult to use. Many people seem to be saying that "if you want to uninstall Ubuntu, just go to Windows Control Panel and uninstall Wubi like you would any other application and it will remove Wubi " But what if I wanted to uninstall Windows 7 and leave Ubuntu on the hard disk? Would I need to start from square one and re-install Ubuntu again?

I just got a new laptop for school work and I've loaded Ubuntu onto it without issue. Now I'd like to free up some space on my desktop to use it primarily as a gaming computer. I had Windows 7 installed long before I installed Ubuntu and I figured that uninstalling Ubuntu would be as simple as just deleting the hard drive partition but I can't see the partition in My Computer like I thought I would and when I googled how to do it I kept hearing people talk about Grub, which I have completely no understanding of. I just want to delete Ubuntu without harming the programs I have installed on my Windows partition.

i had windows 7 pre-installed in my laptop. i installed ubuntu 11.04 by making a bootable disk and did the partitioning so that both windows and ubuntu boot options would come on startup. however , when i switch on the laptop . the options do not come and ubuntu boots as if it is the default. i thought this might be due to a problem with grub 2 so i re-installed it. yet there was no difference. i want to uninstall ubuntu now. but how do it? most guides require me to access windows and create a rescue disk and changing the MBR. but since i cant access my windows partition this isnt an option. so there are 2 options for me - to make grub detect windows during boot and then use windows to make the MBR rite or to delete the system files of ubuntu to make it unbootable?

I'm currently running Ubuntu 10.10 Netbook Edition and Windows 7, and I'm looking to uninstall windows 7.
I have an HP Mini 210-1041NR and it's been running VERY slow so I'm hoping this will help because I haven't used Windows since I got Ubuntu.

Now I would like to uninstall it and use Windows XP instead. But when booting from the winxp disk, the only partition I can see, is the flash drive I am installing from. I was told to uninstall grub, but the fixmbr command doesn't do anything for me.

I dual booted Ubuntu with Win XP, and decided to upgrade XP to Win7. Thought I knew how to do it, so excuse my dumbness. Here's where I'm at: I booted GParted, and deleted the /, /home and swap partitions, making unallocated space. I expanded Win XP partition and tried to re-boot, expecting only Windows to show. Instead, I got the Error 22 error when Grub was the first thing to load. So, back to GParted, deleted the primary partition, created a new bootable partition, formatted it NTFS, and put the Win7 disk and rebooted. This time I got a Windows error "can't load NTLdr".
Rebooted the computer without the disk, and got the Error 22 again. So it seems (?) that I'm not able to change/remove or otherwise, the Grub boot file. So the drive is currently useless, unless someone can tell me how to get the disk back to a bootable state where I can load Win7, after which I can create Ubuntu as a dual boot again.

I've been working with ubuntu now for quite some time. My computer loads grub fine on a cold state boot. It loads fine on my 3 linux based systems when they restart. It gives me a grub 21 error when I choose restart in windows 7. I'm forced to press the power button, and turn it back on- not a huge deal, as its a 100% fix. I'm already booting with rootnoverify, and have checked the command on boot to make sure it was the right grub menu that was installed. I also couldn't find a topic with a problem like this, most were just grub not working at all after install or similar.

I've been serching the forum for hours and every thread related to "GRUB error: no such partition" that i've read relates to fixing the issue for users with windows OS also installed or trying to get windows to boot.
How it happened: I edited partitions and now I get GRUB error: no such partition. I ONLY have Linux installed.
I was able to boot the OS by typing:
Code:
set partition=(hd0,1)/boot/grub
set root=(hd0,1)
insmod normal
normal

I just got a new computer that has Windows 7 Ultimate, and I want to install Ubuntu to a partition that I created. I want to be able to re-add my Windows 7 to the GRUB, without erasing either of my operating systems. I have seen people that changed the menu.lst file, but got the BOOTMGR not found error. Will I get this problem? My computer came with one drive split in two partitions, WIN7 and DATA. I took 150GB out of the DATA partition to make a new one called Linux. So, how would I put Windows 7 in GRUB, but not erase eithr operating system, and will I get the BOOTMGR not found error?

I am having trouble getting a dual boot setup on Ubuntu remix on a netbook. The install went fine, but then windows would not book. I had a windows error. So I reinstalled windows, and rebuilt grub. Now when I try to launch windows from the grub menu it says "error: no such device: 0a82ff1982ff0849". How do I go about fixing that? I can boot to Ubuntu fine now.

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?

I am having some problems uninstalling wubi. Its not in the uninstall programs or coming up and a boot option when i boot my computer anymore. So i went out and downloaded the newest version, and tried to install it. Cause i thought that it had been removed maybe by anti-virus or something. When i clicked on it to install it said i had a previous version that i had to uninstall. So i clicked OK. It started to uninstall and then i got an error message. I tried it again and got the some error message.
