First of all, I'm a linux noob (I've been using linux for a about four-five years, but only fixed problems as I got them though usually I just reinstalled everything).
I have recently installed kubuntu 9.04, then upgraded to the latest Kubuntu (10.4). Everything went smooth and I have used it OK for about two weeks.
After the latest security/bugfixes update, the bootloader got corrupted.
Can I restore it from the 9.04 boot CD/DVD, or do I need a special rescue system?
Should I get a new live DVD for 10.4 and fix it from there?
Also, what do I need to actually fix? What utilities do I need? (What should my steps be?)
