Hai

i am having windows xp and redhat linux 9.0 on my pc. both were booting from grub loader.i recently re-installed xp, after that i can't find my grub loader. xp resides on hda1 and linux on hda3. is there any method to recover my grub loader.

hi there
boot into rescue mode from ur PC

at the end run

chroot /mnt/sysimage

and u will dropped to a shell of ur redhat system
to reinstall grun run

grub-install /dev/hda

this will install grub on the MBR of hda

regards

This is not very intelligent option, but try installing RH9 all over again(DUH !!?). But it surely works.

windows always overwrites the boot sector. It thinks its the only OS.

If you can boot your linux partition with a floppy, or failing that if you have a copy of knoppix boot into linux.

run grub-install /dev/hda

Look at /boot/grub/menu.conf

There should be an entry for windoze, if it helps here is a copy of my menu.conf as an example

Good luck!

From your rescue environment, find your boot and root partitions (if they are different) mount the root under /mnt and if there is a boot mount that under /mnt/boot.

Run grub-install --root-directory=/mnt /dev/hd? (where ? is the letter of your drive.)

You may have to set up your MS boot stanza in grub.conf

what option are u talking about??
