Well, reinstalling will be fun.
And when you are finished having fun, it may be a good idea to make a remaster or use clonezilla to make a backup.
Unless, of course, you like
to reinstall having fun

Even a remaster would not have helped him out in this situation. Just saying.

True, true, true...
What a re-master
could have done for him (even in this situation), would be to give him a reference he could boot into, even after re-installing with the 2011.9 ISO from which to determine what additional apps he installed, and what (if any) system-wide customizations were made...
