If you have a repair disk for Windows, then run it. It should repair
Windows boot setup, and you will not be able to boot into Linux, but
that's fixable too: Run the install disk for the Linux distro, and
it should have a boot repair section, which you need to run. I don't
know how Ubuntu does it, but in PCLOS, for instance, you would run
"redo mbr." I don't know how to fix it without a Windows repair disk,
and I doubt that reinstalling Ubuntu would help.

(For anyone running this kind of dual boot that's still working,
Windows has a means of making a repair disk. You should do it now
if you don't have one!)
