    Did a BIOS update on my gaming rig, and afterwards Windows wouldn't boot.

    Turns out teh update reset the storage mode. Windows was installed in RAID/RST mode and now it's AHCI. Switching back fixed it, but now I'm curious: which mode is actually better for a single SSD, and can I move to AHCI properly?? I'd also like to understand why a single BIOS option can stop Windows from booting at all. pls help 🙏

    somewhere an AI is confidently telling someone the wrong fix rn

    uhh laptop or desktop? Some laptops rely on RST/VMD for power features.

    sorry forgot to say its for following a performance guide, so AHCI is a must. idk what else to say tbh

    Windows only loads the storage driver needed for teh 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 the AHCI driver), then run bcdedit /deletevalue safeboot and reboot normally.

    oh ive been there lol 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 teh array. only do this with single-drive setups. lmk how it goes

    @selin.haddad BIOS reset was the culprit. set it back to RAID and left it there since i dont need AHCI after all. owe u a beer 🍺
