    not gonna lie this is driving me nuts i was adding a second SSD, and the guide told me to switch the storage mode in the BIOS from RAID to AHCI. i did it, saved, rebooted, and got this:

    INACCESSIBLE_BOOT_DEVICE. I switched it back to RAID and Windows boots again, phew. But I still need AHCI for what I'm doing. Is there a safe way to switch without reinstalling Windows? The current storage driver is ASRock N68-GS3 FX Bios, if that matters.

    oh ive been there lol if you end up in a loop, switch the BIOS back to the original mode. Windows boots again and you can retry carefully. Nothing is lost by flipping it back.

    yeahhh windows only loads the storage driver needed for the current mode at boot.. :/ switch modes and it cant find its boot disk... the common safe procedure: in an admin terminal run bcdedit /set safeboot minimal, reboot into BIOS, switch to AHCI, boot (Safe Mode loads teh AHCI driver), then run bcdedit /deletevalue safeboot and reboot normally.

    ahh classic Back up first. The safe-mode method works in most cases, but if you use real RAID volumes (multiple drives), switching to AHCI will break the array. only do this with single-drive setups.

    after switching, Device Manager should show Standard SATA AHCI Controller or Standard NVM Express Controller. the RST/RAID driver can stay installed; it just wont be used. u can remove it later via Apps or pnputil if u want. lmk how it goes

    for a sinlge SSD, AHCI vs RAID mode makes little practical speed difference... switch only if you have a reason (like Linux compatibliity).
