Grub recovery

29 May 2007

Need to recover your Grub bootloader after Windows has overwritten the MBR on a dualboot system? Here's the howto in a few quick steps.

  1. boot from a Linux LiveCD like one of these.

  2. type 'sudo grub' to open the grub prompt (e.g., "grub>")
  3. type 'find /boot/grub/stage1' to find a installable location (e.g., hd0,2).
  4. type 'root (hd*,*)' ... and replace the asterisks with the output from step 2.
  5. type 'setup (hd0)' to install grub to the mbr.
  6. type 'quit' to exit grub.
