Came home this evening and hit the power button to wake up the ol’ Optiplex. It started out normal but never got to the screen where I’m supposed to enter my password. It was unresponsive for several minutes and then I got a BSOD with the error INACCESIBLE_BOOT_DEVICE. Huh? Nothing has changed in the machine lately other than the installation of a game or two.

I’ve tried booting into safe mode, but I get the same error. I tried whatever they now call the last known good configuration, but that doesn’t do anything either. It says it’s trying to repair the problem (yeah, right) but I get stuck in this same cycle of error and reboot. All extra hardware devices have been unplugged. All other SATA ports other than 0 have been disabled. SATA mode is set to AHCI. What am I missing? What do I need to do to get this PoS running again? HELP!
