hello. So I got a old gateway im toying around with. I formatted the harddrive and everything. I took the wires out and put it back in. But now It wont boot from the cd like I tell it to do in the bios (phoenix bios) and a message comes up saying " Please remove any removable media" Or something along those lines. I have nothing in the cd tray or floppy a. Whats up with this?
