Ubuntu :: How To Remove Grub
Aug 27, 2010
I've had ubuntu installed on my system but removed it. If I try to start my computer (which should have Windows 7 on it) it gets "grub rescue>", due to that the only OS I have available is ubuntu from a CD (without actually installing) seeing as it won't load Windows. How can I remove grub? I searched on google but nothing I found works.
I suppose it's not just removing file system/boot/grub, I'm afraid doing that might screw my computer up even further.

I'm just slightly confused here, but... what the? Why does installing grub-doc remove BOTH grub-pc, and grub-common? So basically it seems like by installing grub-doc, I have uninstalled grub totally (yes, it is still there as the bootloader, but i have no way of updating it now!) from my system. What's the conflict between grub-doc and grub-pc, such that grub-pc has to be removed?

So I wanted to get rid of ubuntu 10.10 on my HP pavilion dv6 laptop as I wanted to make some hd space. Its a dual boot with windows 7. I deleted the ubuntu partition and expanded the windows partition to fill the whole hard drive again. When I restarted my laptop I got the "error: no such partition. Grub rescue>" message.
I tried inserting my ubuntu 10.10 boot cd but whenever I boot from the cd I get the exact same grub rescue error. Is it possible to remedy this situation from the error? I am currently unable to download a windows recovery cd so I'm stuck in the grub rescue page unless its possible to fix this mess from the error prompt.

I have installed 11.2 next to my 11.1 version I have a few big problems with 11.2 and I like to completely remove it. there are 2 grub's active now. I want to remove the 11.2 grub and make the 11.1 grub master again, but I do not know where to change this, the MBR points to the 11.2 grub and changing menu.lst probably does not have any effect.

"Ubuntu, Linux 2.6.31-19-generic-pae"
"Ubuntu, Linux 2.6.31-17-generic-pae"
"Microsoft Windows XP Professional"
1st - Through Synaptic I removed:
linux-headers-2.6.31-14

I need to reinstall both windows and ubuntu as dual boot. I tried to install windows 7 from the recovery partition but after windows starts the recovery and then does its first reboot it always loads to the grub prompt. I booted with ubuntu 10.10 live cd and wiped off all the partitions except the windows recovery partition and I tried sudo ms-sys -m /dev/sda3 which is supposed to restore the windows mbr but still when I reboot it just boots to the grub command prompt with windows only partially installed.
If I completely wiped off the old ubuntu partition and the windows partition then how can grub still be loading up? where is grub located? How to completely remove grub. I don't have a windows recovery cd, I only have the recovery partition which is still intact. I have tried to install ubuntu first and make an ntfs partition but when I try to install windows the recovery partition program says there is not enough space to install windows but there is 260gb.

I can't figure out how to remove a Ubuntu distro in grub that I no long have installed. I have Win 7, Ubuntu 10.4 installed but when I boot my grub menu shows Win 7, Ubuntu 10.4 and Ubuntu 10.10 that I have removed from my hard drive but still shows up in the menu. I have been trying many commands in the terminal menu to edit grub but nothing shows me how to remove a menu entry.

The other day I repartitioned the drive I had ubuntu on and today I go to start my computer and I get a grub rescue prompt. I tried the MBR fix on the vista install CD, but that didn't work. I'm basicly stuck on this liveCD until I can get this fixed.

How can I remove entries manually that were automatically generated by grub 2? I have the scripts I need to add my entries, but I don't want the osprober to keep adding new entries. Even if I make the 30_osprober script non-executable, the entries are still there. Can I do this without "breaking the rules" and editing the grub.cfg file?

I have installed Kubuntu on a usb stick. I installed version 9.04 from a disk that came with linux magazine. After installation I can only boot pc if the usb stick is plugged into pc before I turn it on. I then gat a menu with 5 options. The first is Kubuntu and the last is Windows XP. If I try to boot my pc without the usb stick plugged in I get a GRUB error message.
I think this is the GRUB menu which means that it must have amended the Master Boot Record. If I try to boot my pc without the usb stick plugged in I get a GRUB error message. This is generally a minor inconvenience and a great security measure. My worry is that I am notorious for losing usb sticks. If I lose this one I wont be able to boot pc. Is there a way to remove GRUB and restore the MBR?

I have windows XP on one disk, I added another disk and I installed UBuntu 9.10 on it. I wish to temporarily remove the ubuntu disk, however grub cannot load unless that disk is connected. It appears that grub has got to the windows disk and my system was booting from there. I wish to remove grub from all disks, (or at least the windows disk). I tried removing it from the synaptic package manager, but it's still there (but it looks different, maybe another version loaded or something). I'd like to just be able to boot from either disk using my bios boot menu.

I am dual booting Windows 7 sda1 and Ubuntu 9.10 on one hard drive. The second hard drive is data only. My grub menu shows at the end of the menu
Windows 7 sda1
Windows 7 sdb1
I think this is because I had a bad "A" drive that I just replaced and before that I did a lot of changing of the mbr and grub commands. So there must be something on the "B" or second drive that is causing this. Right now everything is fine with my computer and this is just house keeping. I would like to delete the "Windows 7 sdb1" menu Item if possible. Just to be clear, windows boots with the sda1 command (first menu Item), and the "windows 7 sdb1" does nothing at all.

I have OS X, Ubuntu 10 x64 and Windows 7 x64 installed on my Macbook Pro new unibody. Right now when I choose Windows or Linux in the rEFIt boot menu both options take me to the GRUB menu, and I can boot everything but it's a bit redundant and annoying.

The latest update installed a new linux header 2.6.35-23. The older version 2.6.35-22 also appears in grub. What would be the sense in keeping them both? And if not required how do I remove the older version from grub?
I tried: "sudo update-grub" which changed nothing.

I recentely installed ubuntu to my second hard disk (on the first i had windows 7 and data), but the hard disk that i installed ubuntu on broke, so i had to trash it. The problem is that i have an external disk reader that is only bootable after i booted at least once into windows. So basically i can't boot using either Windows or Linux disks, nor can i boot into the os itself. When i start the computer i get something like device not fount and a long code, then a prompt shows up (Rescue GRUB). What do i need to type here to remove grub and be able to boot into windows?

Sup Ubuntu forums, before I begin I would like to say that I do indeed thoroughly enjoy Linux, especially Ubuntu. and I do intend on coming back to it later on down the road.
Okay, so what I want to do is completely remove Ubuntu and the Grub Bootloader and install the Windows Bootloader but I am not so sure how to accomplish said task. I bought my laptop with Ubuntu 10.04 installed on it and have since then updated to 11.04. I don't believe windows was previously installed on the laptop but I could be wrong.
I have a Ubuntu 11.04 Live CD, a Windows 7 Ultimate Installation CD, and a Windows 7 Recovery CD.
I have heard that you can remove all the necessary partitions that have Ubuntu/Grub in them through the Ubuntu Installation process but I am not sure which partitions to remove.

I was trying to load up Ubuntu 9.10 on a thumb drive to load look at the files on a computer with a dead disk drive, I couldn�t boot up on the other computer, but that�s another story (yes the drive was marked as bootable)
When I restart my laptop whose diskdrive I used to install Ubuntu onto the USB drive, I get a GRUB error �No such device and can load anything unless I plug back in the USB drive. When it is plugged in, the USB boot is the primary (1st in the list) boot. I tried editing the .lst file on my laptop�s drive but it only has its kernels listed. Anyone know how to make my system quit looking for a USB mounted kernel? Or at least not fail if it can't find one.

I'm running Ubuntu 9.10 dual booted with Windows XP. Ever since I installed 9.10, I get a long list of OS's (actually, multiple repeats of what appears to be the same Ubuntu install), and I can't get rid of them.I've looked through various tutorials and the GRUB 2 Community documentation (https://help.ubuntu.com/community/Grub2) but I still can't get rid of the menu items.I edited the 40_custom file and was able to add the entries I wanted to see, and then chmoded 644 all the other files in the /etc/grub.d directory and run update-grub.The custom entries do appear at the end of the menu now, but the old entries are still there as well. This is what I get when I run the update-grub:
Code:
yoodle@HANSOLO:/etc/grub.d$ sudo update-grub
Searching for GRUB installation directory ... found: /boot/grub

I had Kubuntu 9.04 and Windows XP on a Dual Boot. I upgraded using the update manager to 9.10. (I know, I'm a fool.) The Kubuntu install stated freezing hard on startup, just after the GRUB OS selection screen, at a blinking cursor and otherwise blank screen. I'm pretty sure 9.10 will work great from a fresh install, but the live cd freezes after main Kubuntu boot screen and even Windows live cd only shows Windows partition. fixmb, fixboot, bootcfg etc. do NOT replace the grub as desired.

Is it possible to remove the entry 'Other operating systems' from the Grub menu display? I mean that it can be commented in menu.lst,but will it affect other OS(Win XP in my case) in any way?

I have windows Vista and Ubuntu 9.04 on my asus laptop and use grub as boot manager. I tried to reinstall windows vista with the recovery CD delivered with my laptop in order to just get rid of the old installations. The Installation was OK, however when rebooting windows doesn't come up printing the error could not load GRUB Error 22.
Now I think I should remove grub from teh master boot record, and the system will supposedly work.My question is is this a solution and how do I reformat the master boot record? Can I do it with the Ubuntu instalation CD?

First & second entries listed above don't work. How can I remove them safely?

Is there any way to simply remove grub? Does GRUB reside in a specific partition? Do I have to just delete the partition that has GRUB on it?The way my bootable partitions work is something like this.
1)Installed Vista
2)Installed Ubuntu
3)Thought I removed GRUB
4)Put in new HDD(1) and installed Win7 onto it
5)Put in another new HDD(2) and put another Win7 onto that (but I disconnected every other HDD so that the bootloader would be written onto the new HDD(2). When I have all my HDD's plugged in now, I get a GRUB load error (I think it's 21).

I followed the Grub 2 Basics steps to remove Grub 2 kernel listings.
However I'm stuck with 3 older versions that was completely_removed from Synaptic (kernel/headers/generic), but remain in grub.cfg.
Quote:
Here is my current grub.cfg:
(How do I remove *.14 *.21 *.22 from my menu entries Ubuntu-tweak is not an option for me. I like it old-school or with the tools at hand.)
Code:
I considered changing permissions for grub.cfg, but update-grub and new kernels will revert my changes.

I have so many entries in GRUB and have to actually scroll down so much to see windows entry. How do I remove unwanted entries in GRUB? Also How can I make a background picture appear when grub manager comes up?
