I don't think it's the hard drive because most likely the hard drive is SATA and even if it was IDE, it's on separate channels. Most likely the secondary IDE channel is still enabled and it's looking for an optical IDE drive that isn't there and keeps hanging because it can't find it. Like J03 and I have said, go into your BIOS, most likely under Secondary Master and Secondary Slave, it's set to Auto. Make sure to set those to either Disabled or Off, depending on your options. That should take care of things.
