I'm back from safe mode, have good and bad news.
Drive C formatted 99%, and later could not continue, but most
hidden files are gone except for something i pasted in there.

Bad news is, drive E caould not be formatted even in safe mode.

So now do i install XP into my drive C: ?
Then maybe i can try to format E: from here.
I think i figured it out, i'm currently using drive E:, so the
system won't allow me to format it, am i right?
