When starting windows xp pro I get and error message. It does not appear to effect startup as, other than this message, all starts normally (or so it seems). Seems to have come out of nowhere. I had not installed anything, changed configuration, played with the start menu, etc. Has been happening for three days
Windows - No Disk

Doesn't seem to matter which I seled, it just goes away
