Boot issue after bios...

I have a bit of an odd problem, curious to see what guys think.

msi x99 sli plus board

I took out 2 x 780 video cards and replaced them with an old 450 GTS. And started the pc. I get to bios, but then after bios instead of launching windows it just hangs with a flashing "—" in the top left corner.

I cleared bios, reset the pc, but nothing worked. I then pressed f11 to access the boot menu and tried to boot directly from windows drive, it booted straight to windows with no problem. If I now reset the pc, I get the orginal problem. I figured maybe it's trying to boot to the wrong drive, I checked bios boot loading options but for some reason my boot drive is not listed in the boot order. What's listed is a load of UEFI options and one of my drives (I have 5). So I can't really do much there. When looking at the attached devices on the board explorer, all drives including my boot drive are present.

I pressed f11 again, clicked on my boot drive and got back to windows. Restarted the PC in advanced start up and ran the boot manager troubleshooter, it told me it couldn't fix an issue, but didn't tell me what that issues was...

So what do you guys think? Windows re-install would probably fix it, though with windows 10 around the corner I'm loath to reinstall before its release. I guess corrupt boot manager, but no idea how it happened.
 
Can you get in to the BIOS interface?

Maybe it would be worth flashing back to the previous working one? (Download it first from the MSI site)

Thanks, I'll give it a go. I took some pictures last night of the problem.

This pic shows the boot list I have -
