Removing Grub

[towheedm]

I came across this thread during a search and registered just to say this.
http://www.linuxforums.org/forum/ubu...ard-drive.html
I have the same problem as danost, however grub got installed on my Windows drive while re-installing 10.10. This drive is sda. My sdb and sdc drives are solely for linux and are configured with seveal raid0 partitions.
I can still access my Windows installation from the GRUB menu. However, when I try to boot from my Windows drive, it drops to the grub rescue prompt. For me, this really is not a problem since I can still boot Windows from GRUB.
Only this week I decided to try and repair the MBR of sda. But for me, running FIXMBR and FIXBOOT did not help in any way. I stil get the grub rescue prompt if I try to boot from this drive.

Is there anything else I need to do? Any help will be appreciated as my only other option would be to re-install and see if that helps.

I'm a little confused about your problem because of the above quote and your later statement that you can boot windows from Grub? If you have your Linux distributions on sdb and/or sdc, then most of your Grub files are on one of those partitions and only the 512bytes are in the mbr of sda. You will need whichever drive has your Linux boot files for Grub attached in order to boot.

The fixmbr commands may be different depending upon the version of windows you are using.
Which windows are you using?
Do you have a full installation CD for it?
Which Linux distribution(s) are you using?
Posting some information about your setup would be helpful. Go to the site below and download the bootinfo script to post here.

Thanks for the reply. I'll be more specific. I have XP Pro installed on sda, my main linux installation (Ubuntu 10.10) installed on sdb and sdc. I do have my original XP CD. My previous Ubuntu installation was 9.10 installed on sdb1. I did a full install of 10.10 instead of an upgrade from 9.10. Before installing Maverick, I could select to boot into XP from the BIOS boot select menu if I wanted. Of course, I could also select it from GRUB's menu items.

During the installation of Maverick, I inadvertently selected sda as the drive for the installation of GRUB. During the installation of the bootloader, I lost power to my PC during GRUB's installation. I restarted the installation of Maverick, this time making sure I selected sdb as the drive for GRUB. The installation finished successfully and I could select Maverick or XP from GRUB's menu item and boot either one without any problem.

However, because the initial installation of GRUB on sda did not complete, I cannot boot XP by selecting the drive from the BIOS boot menu. When I do this, it drops to the grub rescue prompt.

The problem with sda appears to be with the MBR since I can boot XP from GRUB's boot menu. I need to be able to boot XP from the BIOS boot menu because I'm always testing.

This is my drives configurations:

/dev/sda: 80GB IDE - my original drive dedicated to XP with several partitions only for XP. This was my original config which I left as is.

/dev/sdb and /dev/sdc: 500GB SATA: Contains lots of ext4 partitions for use only with linux. They are configured thus:

/dev/sdb: MBR bootloader for GRUB2 for Maverick.
/dev/sdc: MBR bootloader for GRUB legacy for Fedora 14.

/dev/sdb1: /boot partition for Maverick.
/dev/md1 (sdb5 and sdc5) RAID0: / partition
/dev/md2 (sdb6 and sdc6) RAID0: /home partition
/dev/md3 (sdb7 and sdc7) RAID0: /tmp partition
/dev/md4 (sdb11 and sdc11) RAID0: partitions for VM's using VMWARE
/dev/sdb8 and /dev/sdc8: swaps
/dev/sdc10: Fedora14 installation

And several other partitions for music, movies and other misc stuff.

Hope this info helps you to help me. Thanks.

Then you need to boot windows boot files in the master boot record of the sda drive. If you have your xp installation CD, you should be able to repair with that. You should be able to google something like "repair xp bootloader after installing Linux" to find a method to do it. You could also go to some windows forum or support.microsoft.
