Possibly, but i've gotten messages like this plenty of times when i've been messing with things, but every time i've succesfully recovered everything. You can't just tell someone you have an error like that. You need to tell them what happened to cause it. That's the only way you to solve it. Errors like these just don't happen spontaneously.
BTW: You can only get a boot sector virus from floppy disks, harddrives, or other hardware bootable media.
