After re-installing Windows XP on my Laptop (I dual-boot Windows and Ubuntu), my grub (linux bootloader) was overwritten. It is easy to fix this, so I once again can select between Linux and Windows at boot time:
- Boot Ubuntu Desktop/Live CD
- Open Terminal application
- Mount root partition of local Linux Install (eg. mount /dev/sda2 /mnt)
- Reinstall grub: grub-install –root-directory=/mnt /dev/sda
- If you get errors try: grub-install –root-directory=/mnt /dev/sda –recheck
- Remember to use the correct device names above.
