Select xp to go to (level 3 menu): xp, Grub console, dos
Select the Grub console and return to the first menu. Select each option to go to the corresponding system.
After the mbr is rebuilt for some reason, grub is gone. Start the computer and go to the second-level menu, choose "Grub"> "Tier 3"> "Tier 1"> "Tier 1"> "vista"> "bootmgr no file"> "vista.
Then, reinstall Grub and create a menu. lst file under C: \ grub \. The content of the file is as follows:
