I put together a new pc and put my old disk drive in it, which is 80 gig and was working fine in another computer. It has a chaintech v915p motherboard, and a intel 3.2 processor, with 512 memory. I turn it on and it powers up and gets to the screen, do I want to boot in safe mode or normal. It doesn't matter which I pick, it reboots and comes up to the same screen to boot up in safe mode or normal. The BIOs see the disk drive and the size of it. I have checked the jumper and it is right. I have disconnected the cd and diskette drives.
