You'll keep getting lots of people telling you how to avoid and fix this
problem using GRUB. Those solutions work but they're hard to learn and
in my opinion messy. Here's my view:

GRUB should not be used as a boot manager. It is more a kernel manager
and should be allowed to manage the startup of only one installation. I
always install GRUB to the same partitions as root (/).

GAG is a boot manager which sticks to it's job. It installs in MBR and
you just point it to any bootable partition - then GRUB or whatever can
take it from there.

Why do it this way?

If you (re)install anything which spoils you MBR you just reinstall GAG
and point it to the bootable partitions your using. If you have GRUB
installed to MBR you have to configure it to boot to the correct kernel
and it uses a tricky syntax which makes it hard to edit for mere
semi-nerds.

An even more compelling example is the case I hit too many times.
1. Install Windows (writes to MBR)
2. Install Ubuntu (overwrites MBR)
3. Install another Linux (overwrites MBR again)
