Win 7 won't bootup on my new computer

[pokypup]

I just built a new quad core computer. Everything is new inside except the hard drive, I installed the drive from my D50 single core 3.46 Celeron. Win 7 starts to bootup, starts to form the Win logo, crashes and reboots. I ran the repair program multiple times, tried to do a recovery all with the same results. The error message says that there is new hardware and it might hurt your computer so Windows stop running.

The drive worked fine on the old computer just 20 minutes before.

I also bought a new 1 TB drive that I loaded my older copy of Vista on so I could communicate with the outside World.

I just moved and I can't find my DVD w/ Win 7 on it.

Anybody have a solution.

Make sure AHCI is disabled in the BIOS, as it was probably disabled on the other machine when Windows was installed. If and when you get into Windows, enable Windows to use AHCI, then enable it in the BIOS again.
