Glad it fixed your problem. It's still possible to get a boot virus in
linux, but you'd have to have enabled write access to your boot partition
or have been rooted. Or if you connect to the internet while running a,
hmmm, "less secure" OS you open some doors. Typically, the BIOS just
complains because it notices your boot block has been changed to mbr
or lilo or something it doesn't recognize. In other words, you're not
really wrong that you could get a boot virus, it's just that (typically)
that's not what the BIOS is really complaining about.
Good luck,
Steve
