Use BIOS AHCI mode for Windows 7

If your machines are running in ATA mode you could be missing out.  However,  changing over to this mode can cause some issues (a blue screen,  indeed) in Windows 7.

If you do want to do this you can make the change and avoid the blue screen:



1. Exit all Windows-based programs.

2. Click Start, type regedit in the Start Search box, and then press ENTER.

3. If you receive the User Account Control dialog box, click Continue.

4. Locate and then click the following registry subkey:

HKEY_LOCAL_MACHINESystemCurrentControlSetServicesMsahci

5. In the right pane, right-click Start in the Name column, and then click Modify.

6. In the Value data box, type 0, and then click OK.

7. Do the same thing for IastorV service

8. On the File menu, click Exit to close Registry Editor.

9. Reboot and press F2 to go into BIOS: there enable AHCI mode
