Hello People,

I checked similar topics but i have a little different scenario.

I have 2 hard disk , the primary master (hda) is the bootable disk with WIn XP in it , which actually overwrote the grub boot loader when i was reinstalling Win XP , now iam not able to boot into Ubuntu (which is in secondary slave or i could attach it in secondary master too) and i want to re-install grub in primary master ... towards this i do following :

1> Load Ubuntu CD and rescue the broken system
2> Run the command line and run the following cmd :
But both the cmd fail ..... what could be the reason for this ?
Is it because the concerned binary and config files are in the other
hard disk containing Ubuntu , (this has all the partition ie bin , sbin, var,opt, usr, swap etc )...

Please write me detailed steps or some site to read through ....

Thanks in advance

Regards
Vikku

You don't give the failure message, but assuming it is c"command not found", try grub-install

Hello Bill,

It just says "Grub installation failed" but no pointers whatsoever...

Oh I just noticed. What is the prompt you are at that increments a>, b>, etc ?

The disk may be /dev/sda rather than /dev/hda (grub uses different naming so don't mix the two).

Try fdisk -l

Hi, Vikku

First off all swap the drives e.g.
hda > hdb , hdb to hda
Boot your cd with grub and enter the grub shell by typing grub as root
i assume your partition with /boot/grub will then be hd0,0
type:
root (hd0,0)
setup (hd0)

to make windows think it's still on the hda drive,
edit the menu.lst like this

title Windows
root (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
makeactive
chainloader +1

hope this helps
