If you change SATA Operation Mode in computer BIOS after Windows OS installation, you will most likely get a Blue Screen of Death (BSOD) next time Windows boots.

To prevent this, you need to make sure the first boot after SATA Mode change is done in Safe Mode.

• Start > Run type msconfig and press Enter
• Change to Boot tab and under Boot option select Safe Mode and Minimal
  
• Clock OK and restart computer
• Now go into BIOS change the SATA Operation Mode from RAID to AHCI
• Let Windows boot into Safe Mode
• Start > Run type msconfig and press Enter
• Change to Boot tab and under Boot option clear checkbox next to Safe Mode
• Reboot computer
