Without knowing about the *nix commands to overwrite the MBR, I guess
you were. If I'd looked at the thread earlier, I'd have pointed them
out to you.

At this point, I'll just suggest you do a web search on the BIOS boot
process, then re-read the grub documentation.

I think that's partly because so many users of MSWindows just want
someone else to hand them a magic solution, and partly because most
users in this situation would be panicked about their data on the
MSWindows drive, not realizing that *nix provides them tools to save
that before they use the recovery options.

And I'll encourage you to go ahead and look up the boot process, for
when you need to do something like this again.

Here's some pages on wikipedia, to get started:

   https://en.wikipedia.org/wiki/Booting
   https://en.wikipedia.org/wiki/BIOS

I don't say I distrust the Boot Repair CD on sourceforge, I just say
that the less people you have to trust to play with your MBRs, the
better.

(If you personally know yannabuntu the developer in charge of the
project, that might alter the equation significantly.)
