I don't understand your comment about restoring "older windows" using the BIOS -- as that does not make sense to me.

And then you disabled all USB support in the BIOS -- what did you think THAT was going to accomplish?

You said you removed that battery -- so is this a laptop? Asking because you posted this in the DESKTOPS section.

What, other than USB, can your PC boot from? 

If there is nothing else, then you would have to reflash the BIOS and without a way to read a file from USB or something else, YOU can not NOW do that.
