Grub problem

zahadumy · 11-24-2005, 05:04 PM

I deleted one of my Windows partitions, so my linux partitions changed their names, and grub won't work any more because of this.
I did this before and everytime it worked fine, I don't understand why it doesn't work this time. That's how I did it before and how I try to do it now:
I boot with my 1st bootable cd and type "linux rescue". After that, you know that at some point you choose an option to mount your linux partitions. There I get this message:

Code:

An error occured trying to mount some or all of your system. Some of it may be mounted under
/mnt/sysimage

After I've got that shell, I tried this:

Code:

chroot /mnt/sysimage

and I've got this message:

Code:

chroot: cannon execute /bin/sh: No such file or directory

Since I couldn't chroot to my Fedora partition, I tried this:

Code:

mkdir a
mount /dev/sda11 a
chroot a
grub-install /dev/sda

and I've got this message:

Code:

The file /boot/grub/stage1 not read correctly

After I mounted my Fedora partition everything looked fine there... What should I do to reinstall GRUB? Thank you.

If you can mount Fedora, you might be able to repair grub without re-installing. I assume grub is still installed to the MBR; it just can't find the rest of itself because partition numbers have changed.

Edit /etc/grub.conf and /etc/fstab to show the new partition numbers for Linux.

In grub.conf, the location of the root of Fedora probably changed, as well as the location of vmlinuz.

In /etc/fstab, the /dev/sdx numbers may now have to be changed to correctly reflect the mount points.

After I deleted that partition I told you that I couldn't make grub work, and I had to rewrite MBR with my Windows XP bootable cd, because I had no operating system and I had to search the net to solve this. Since I couldn't find anything useful, I wrote this post here. So now GRUB is not any more installed on MBR. Thank you.

*** EDIT ***
I solved my problem. The problem was I had in /etc/fstab one entry for each Windows partition, and after I deleted one of them the last entry pointed to a partition which didn't exist any more, and that's why it failed to mount my system under /mnt/sysimage. I didn't think about this... Thank you.
