I see no answers to this, so I will tell you this: If you have a CD (or USB
drive) with the Super Grub Disk from www.supergrubdisk.org, you will be
able to get to your linux installations no matter how badly you mess up you
MBR. It is usually quite difficult to cut yourself off from an existing
installation, because usually the new install process will find the old
installation and include it on the new menu.
