Will XP Pro Overwrite the MBR? (GRUB question)

[Boulder_Bum]

I'm upgrading my XP to Pro on a dual boot system and was wondering if doing so will screw up the GRUB boot loader thingie. If it does, how can I reinstall and configure it to run Linux too?

If you install the Linux bootloader (Grub) in the mbr instead of the boot/root partition, then yes reinstalling any version of Windows will 'reset' the mbr back to it's original state.

You will need to either use your Linux bootdisk or installation cd in rescue mode to boot your Linux system.

After that (as root) run

grub-install /dev/hda

Search the LNO forums for 'grub-install' and you should find additional info to help.
