After changing away from raid, laptop does no longer start

[Ruby437]

So I changed away from raid to ahci, and it refused to boot at all, windows said the something was wrong: INACCESSIBLE_BOOT_DEVICE After changing back I was able to boot again without a problem.

Also on that note: the Dell OS Recovery Tool seems to fail to extract the image on 2 different usb drives and 2 different computers.

Hello, I find a solution!

1. Run a Command Prompt (Admin)
2. Set reboot on safe mode, typing this command: bcdedit /set safeboot minimal
3. Restart and enter BIOS Setup
4. Change the SATA Operation mode to AHCI
5. Save changes and exit Setup
6. Windows will automatically boot to Safe Mode
7. Run a Command Prompt (Admin)
8. Set reboot to normal Windows, typing this command: bcdedit /deletevalue safeboot
9. Reboot once more and Windows will automatically start with AHCI drivers enabled

For me the solution it works! Good Luck!
