A bash script to fix the grub menu.

Usage:

Simply run the script:

  1. sudo ./grubfix

It will guide you step by step:

  3.  A star (*) sign after the device id means it's bootable  
  4.  It is not necessary for a system partition to be bootable
  5.  Be careful. We need the device id where the filesystem  
  6.  resides, not where it is booted from.

If it’s more complex than that, then this script also allows you to open a chroot terminal on your target system, run it with -co option:

  1. sudo ./grubfix -co

In chroot only mode, it will not do any additional task other than opening a terminal window with chroot. You can then use that terminal to configure your target system and install or modify pacakges to correct problems.
