The Glade 4.0

Ever since updating to windows 8.1, I get a bluescreen at startup,

"Your PC needs to be repaired.
0xc0000225 - File \Windows\System32\winload.efi is either missing or corrupt."

I hit escape and it bypasses the error and boots up anyway.

I've tried using recovery media, nothing fixes it.

Here's what I've learned:
I have two drives, an SSD and a regular hard drive. The SSD is a clone of the original boot drive. Windows always tries to boot off the original drive first, then switches to the SSD when the original fails. UEFI BIOS boot order doesn't let me choose which drive is attempted first, both hard drives are listed as a single generic option, and since the 8.1 upgrade, it always picks the old one.

I need to somehow convince this SOB to stop trying to boot off my second drive.

You can't remove the drive from the uefi boot list?

If I could find it, sure. As I said, when in the UEFI/BIOS screen, the boot order has hard drives listed as a single option for all of them. The drives are not listed individually.

Is the Drive you want to boot to Sata 0? I know on some of the Dells (I know you don't have a Dell, that's just what I work with overwhelmingly) I've had to have the boot drive on Sata 0.

Sometimes there's a sub-menu option for each option, hard drives, CD roms, bootable USB/flash. It may also be listed as boot order. What bios are you running, can you post a shot of the boot options screen?

Found it. I'd been in it twice and not recognized it, due to MSI or Microsoft idiocy.

There's a UEFI BIOS option separate from the boot order called UEFI Device Priority.
It had looked promising before, so I'd gone in there, but the only options for each of the two devices in the boot order was "Microsoft Windows Boot Manager" or "Disabled."

Then it occurred to me... "It's labelled both drives the same thing." So I disabled the first "Microsoft Windows Boot Manager" and it stopped trying to boot off that drive.

Yep, sounds like it was actually identifying the boot sectors on the drive. Glad you got it working!
