If you switch before doing this, you will likely get a BSOD INACCESSIBLE_BOOT_DEVICE.

Step 1:
Before switch, run this as admin. First line will set safe mode, middle two commands check current values, and last 2 commands enable AHCI and NVME drivers.

Copy to Clipboard bcdedit /set safeboot minimal sc.exe query stornvme sc.exe query storahci sc.exe config storahci start= boot sc.exe config stornvme start= boot


Step 2:
Reboot the computer, enter BIOS, change from RAID/RST to AHCI mode, save and exit.


Step 3:
Change setting in BIOS
After windows boots up, run this as admin:
Copy to Clipboardbcdedit /deletevalue safeboot


Step 4:
Reboot and test.





Another alternative method:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\storahci\StartOverride
Change the 0 DWORD value from 3 to 0.
