I have Windows XP, Windows 7, and several Linux distros installed on different partitions. I would like to replace my main Linux installation (an earlier version of Ubuntu) with a newer one. This installation manages the boot menu (Grub2) for the other systems.
How do I do that without losing the ability to boot into Windows and other operating systems?
The GRUB does need to be replaced with a newer version... I am trying to figure out how to do that without destroying my computer.
