Re: [Trisquel-users] GRUB2 GUI?

The process is relatively straight forward. It's not really restoring grub,  
just fixing its configuration.

In case of trouble you must first boot a live media and then mount the  
harddisk and proceed to directly edit /boot/grub/grub.cfg (on the harddisk,  
naturally, instead of on the live media). Just undo the changes that caused  
the problem. You could make a backup copy of the file when it still works for  
reference.
