Initially iam having windows XP and redhat 9 on my system and grub as a bootloader.

Now i have reinstalled WindowsXP again therefore i have to reinstall bootloader ie GRUB.

Is it Possible to Install LILO as a bootloader now???????

if yes how to do it?????

Whenever you reinstall Windows, you will need to reinstall grub. This might work:

1) Enter in rescue mode with your CDROM

2) Identify the root directory by invoking the chroot command:

...# /mnt/sysimage/ (and enter)

3) I don't know which will work better, maybe someone can chime in, but you can try typing one of the following to see if it works:

...# grub (and enter)
...# grub-install /dev/hda (and enter) <--- I'm thinking this one

4) reboot

I'm no expert, but that should get you going...
