I recently installed Xubuntu 12.04 to my entire hard drive, overwriting Windows XP. I tried to load my Recovery Disk in order to overwrite Xubuntu 12.04 and reinstall Windows XP. The Recovery Disk went through all of the motions of writing files, etc. In the end after the computer ejected the disk and said it was ready to restart, it restarted into "grub rescue" error.
How do I reinstall with my Recovery Disk?
