I had linux and windows XP on seperate drives using GRUB as the bootloader and everything was fine. Yesterday, I reformatted my Windows (C
drive and reinstalled windows. Now, windows boots up everytime. GRUB does't boot anymore. I'm pretty sure that my new windows installation rewrote the MBR, erasing any entries that GRUB had in there. My question is, how do I get GRUB back without having to reinstall Linux?
