Shut the computer down for the night last night, boot it up this morning, and get:
Windows Boot Manager
Windows Failed to start. A recent hardware or software change might be the cause.
Status: 0xc000000f
Normal setup is 2 harddrives. Master and Slave drive. Master drive has the OS, games, drivers, etc. Slave drive has the documents, photos, music, videos.
Computer refuses to boot with both drives for whatever reason. Odd since it was running flawlessly since Jan. Unplug the slave drive, get the same error, but hey, at least I get that far..
Reset computer, spam the delete button to load the BIOS.
Reset BIOS
Nothing changed.
Shut computer down
Open the case, Clear BIOS cache with the DrMOS button on my board.
Boot up.
Nothing changed, repeated error.
Shutdown.
Spend some time attempting to find my Windows 7 disc. I finally find it, shove it in, load it to do a repair.
"Windows disc does not match your version of windows."
Complete BS...
Reboot
Try F8 in attempt to load safe mode, or last known good configuration.
Black screen with blinking underscore.
Reboot.
Thought it was a RAM issue, take the sticks out, RAM check them with my other computer. RAM check clears.
This point, I'm fearing the dreaded system reinstallation. But may not have a choice.
Second fear: My WD HDD may be damaged, and a reinstallation may be pointless.
Third fear: Classes startup again Monday...
Plus side: Slave drive as far as I know, is unaffected.
