Could you answer my questions? Maybe (just maybe) if I understand waht is happening, I can help you. I do not know what, if any Bios updates have been used on the laptop prior to my purchase. I bought it from an IT guy that installed a fresh hard drive with Windows XP Pro and it has worked fine for 2 years or so. When the system crashed, I tried to reboot using the existing hard drive without success and tried to reload XP Pro on that drive. I wound up with a hard drive with 2 copies of XP Pro that did not work. The folks at Dell and Microsoft explained that they were eager to sell me Windows 7 and forget XP. I decided to replace that hard drive as I know there is something corrupt on it and it would probably continue to haunt me. My son-in-law is an IT tech guy that lives in another state. He sent me a copy of Windows XP Pro with a fresh key. This is where I am stuck now. When I try to boot from the CD he sent me, I get the message that I posted at the beginning of this thread. When I turn the lap top on with out the cd, if I hit no keys at all, I just get a flashing cursor that will do nothing - or, if I hit F2 it goes to System Info Menu - or, if I hit F12 it takes me to the boot menu.
