How do I reinstall GRUB after Ghost - SuSE


Previously with RedHat whenever I ghosted the partition the mbr would be corrupt...I would use the boot floppy to bring up the root partition and simply run LILO and reboot and the world was right again...
Recently I had to reinstall SuSE completely because I was unable to figure out how to reinstall GRUB after ghosting. I have a SuSE standard boot disk that will give me access to the login screen, once inside root how do I reinstall GRUB into the mbr?.....thanks for your advice

Once you are booted up to Linux, you can run the command:
grub-install /dev/hda

should that be /dev/hda1 or hdb1?

I have the grub boot-loader installed to the mbr....so should the command be grub-install /dev/hda1
OR grub-install /dev/hdb1....? Please advise and thanks for your help homey

not sure if homey has seen this, so forgive me having a go,

grub will think the homey command of hda as the first drive (ide) detected and install to its mbr.

Each drive has a mbr so are you wanting to install to slave drive hdb?

2) if homeys original instruction fails for you, and you have grub installed there is another way.

open a terminal and su to get root access
type grub and press enter
prompt changes to grub> And NOW acts like a bash command editor

try this

grub> root (hd0,0) ##assuming your /boot folder is on /dev/hda1 edit correction
grub> setup (hd0) ## to setup mbr
grub > quit ## to end the sequence nicely

if you have probs with this post your /etc/fstab so we know where your /boot partition is and ditto for /

thanks!

I'm not the original poster, but I just wanted to post a big THANK YOU to those of you that partiicpated in this forum. Specifically aus9, your advice worked like a charm. I had done some repartitioning on my 2nd hard drive, which also had my linux installation on it. Suddenly GRUB wouldn't load, although I could pass the correct commands to it to get into my system. I checked out the grub.conf file, which looked correct, however it wasn't working. Running
#grub, then
>root (hd1,2), then
>setup (hd0)

to install it back to my first disk MBR did the trick! Here I am in Fedora 1 again...thank you thank you!

Dalton
