This computer is highly idiotic.

It just crashed, so I reboot. And then I get this weird, dark error message saying : NTDLR (or NDTLR) not found. Hit any key to restart. And I get the same message every time I hit a key !

I'm panicked, but I think I should try to reboot again, so I reach to the power button, and that's when I realize I forgot I had a diskette in when I tried to reboot. Of course it couldn't work, but my question is this : why isn't my computer simply telling me, as it did before, that there is a diskette in drive A: and I should take it out ????
