Hello Everyone
Just going to tell you for my experience with error code 0xc000185, and how I solve it.
I build my new PC and like you I was getting the same error after post. Then from their I have to press exit to enter the BIOS exit without saving changes and from there, I was able to boot to WIN 8.
I did some reach about this error an it seems to me that this error is not specific. It could be a dying HDD, no or bad connection of the disc drive or simple a bad or loose sata connector.
So this is what I did. I change the MOBO, HDD, disc drive, ram, re-install Win and still was getting the same error. One day while playing Watch Dogs my computer began sounding a constant short beep. I check my MOBO beep code guide and it said it was a power error. Who knew!
I bought a new PSU and change it. As soon as I turn on my PC, not only it boot directly into Win, it did it in less than 20 sec. That was it a bad PSU!
So my friend hopefully his will help you!
