how to reinstall grub with no linux access or boot disk

Hi all,

The story is long but I'll just try to cut to the chase. I used to run Win XP and Red Hat 9 on the same drive. Then something happened and I had to "fixmbr" to access my Windows installation. Now I want to reinstall grub on MBR so that things are the same again. I have no boot diskette.

Also, I cannot write a grub.conf file all by myself, I'll forget the switches and stuff. So I should be able to tell grub to find the grub.conf file which is already on (hd0,2) /boot , when I'm reinstalling it...

Thanks a lot.

From installation cd's, put in disc 1, enter rescue mode

To re-install grub on the MBR
#chroot /mnt/sysimage
#grub-install /dev/hda

In case your grub.conf file doesnt load windows after you re-install grub, try editing grub.conf to resemble something like the below (this is for a single hard drive with xp and linux)

title Windows XP
rootnoverify (hd0,0) #hd0 is hard drive number and 0 is partition
chainloader +1

Since I do not want to be responsible for anything that goes on with your computer please

add windows XP to grub.conf (your distro name)


install grub on mbr (your distro name).

I would feel bad if something went wrong on my account.

Don't worry. If anything goes wrong I'll fixmbr again and revert to my current state. Thanks a lot, I'll try it now.
