    Does not seem to matter which driver version I use if I select AHCI + switchable graphics then I get a BSOD on startup or a crash in windows install.

    It works fine in IDE mode but I have an SSD with trim support so this would be bad.

    I tested on two drives, native IDE and native AHCI mode. If I go to either integrated or dedicated then it works.

    Anyone got any ideas?
