Windows 7: Changing from SATA RAID to SATA AHCI - Help needed!

Changing from SATA RAID to SATA AHCI - Help needed!

I could really use some help with this. I have a HD that I'm moving from one Windows 7 machine to another.

  • The new system is a Gateway DX4860. The old was was also a Gateway DX4820.
  • When I put the old drive in the new computer, I get the Windows Splash screen, the stars begin to appear and it resets.
  • I went back to the old machine and noticed the BIOS setting for SATA was set to RAID.
  • I changed the new system to RAID, it just froze.
  • I put a second drive in the new machine and now it boots properly.
  • I installed the AHCI drivers, changed the registry setting to 0, rebooted the machine, and changed the BIOS setting to AHCI from RAID.
  • When Windows tries to boot, I'm getting the same behavior as before (I get the Windows Splash screen, the stars begin to appear and it resets).
This is for Windows 7 BTW.

Gateway AND Intel have both told me I need to re-install the OS to make this happen. I'd rather not do that if AT ALL possible.

I'd very much appreciate some help with this.

Thanks so much in advance for any help you can provide!

You have a few things happening here, 1st your Windows 7 is probably an OEM (Originaly came w/the system) andassuck is tiedto the original mobo & can'tbe moved.
2nd, you have 1 sys w/ a core2quad processor, and the other has an I5. This means the mobo & memory are different, you have a different setof drivers so thr=e DX4860 will not boot with the older drivers. Normallythis would take aclean install, but being an OEM version - you would need therecovery discsfromthe DX4860.

If you download a plain vanilla disc from the link I'll add below, you can probably do a startup repair or a repair install. Just make sure you get the exact version and platform that is currently installed.

That all being said, when swapping major components/systems, it is always best to do a clean install.
