[SOLVED] BSOD: Inaccessible Boot Device when switching to AHCI

[TopHatterCT]

So I finally made the jump to a new SSD to re-energize my ancient Intel X58 system. Cloning went fine, fired up the new drive and... meh, I didn't feel that much improvement. Heard that ssd needs AHCI to run at full whack, so into the bios I went (non-UEFI btw, just the good ol' legacy) and switched everything that can be switched to AHCI as such (SATA configuration and Marvell SATA 6G controller mode). And there afterwards my pc said "nope" and went bsod. Is there anything I can do about this? Thx alot in advance.

If Windows was installed while the original storage drive was set to IDE mode, then Windows must be told to boot from AHCI mode.
