Today I tried to use MSI's BIOS updater program thing. I used it, and it downloaded an update for my BIOS. To install it, my PC had to restart. Upon doing so, I was locked at the Windows Boot Manager with no options aside from "Insert Windows 8 install disc" which I do not have.

In the MSI boot menu, I thought I fixed the issue by booting from my SSD. It went back to the usual desktop, but to make sure it was fixed, I tried restarting my PC.

Now I am locked at the Windows Boot Manager menu and my PC refuses to acknowledge keyboard or mouse inputs. Both the keyboard and mouse are wired but they do nothing.

MSI Z87-GD65 on Windows 8.1.

What the f*ck do I do? I was unable to find anyone with a similar problem and I am now 100% unable to do anything else now that keyboard input is disabled. This is posted from my phone as I do not have another PC. Please, please please help, I need this computer for work.
