I have installed Windows 7 on drive which was in IDE mode. When I have changed mode to AHCI OS didn't start (I know. AHCI drivers are needed.). Unfortunately when I back to IDE mode, OS still won't start. Computer starts, Windows loading logo apears, but after few seconds it reboots. Probably my OS is corrupted. I tried to use recovery drive, but it didn't find any problems. Fixing MBR also didn't resolve my problem.
Have you got any suggestions?
Thanks in advance.
