Dual Boot Ubuntu/Vista GRUB Error 21




Issue



In the case that you are prompted with a GRUB error 21 on a Vista and Ubuntu dual booted PC, then it may be due to the fact that Linux mbr can't be found.

Solution


Use the Linux installation CD to fix this:
  • open live cd
  • open terminal


sudo grub
find /boot/grub/stage1 or find /grub/stage1
root (hdX,Y)
setup (hd0)
quit



Restart your PC it should be fine.
