Reboot loop after installing motherboard and cpu Windows7

Installed an asus motherboard and needed to change the sata drive from ide to AHCI. Every time Windows 7 started it would reboot. Hooked the hard drive to another computer and did the fix then installed it into the new computer and it worked.I had to do the fix it option.

1. First DO NOT change SATA hard disk mode settings in BIOS, leave it to the default settings which were used while installing Windows.
2. Now start Windows and type regedit in RUN or Start Menu search box and press Enter. It'll open Registry Editor.
3. Now go to following keys one by one:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\msahci
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\pciide

In right-side pane, look for a DWORD "Start". Double-click on it and set its value to 0 (That's zero and not alphabet O).


4. If you are using RAID or other interface, do the same thing for following key as well:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\iaStorV

In right-side pane, look for a DWORD "Start". Double-click on it and set its value to 0 (That's zero and not alphabet O).

5. That's it. It'll reset the hard disk mode settings in Windows registry. Close Registry Editor and restart your system.
6. Now enter into BIOS settings and change SATA hard disk mode to AHCI or RAID according to your requirements.

7. As soon as Windows will start booting, it'll automatically detect the change and will install the appropriate drivers. Once the drivers are installed, Windows will boot without any problem and you'll not need to reinstall Windows just to change SATA hard disk mode.
