So I have been having and issue with my desktop. It won't boot into Windows anymore. Instead I'm stuck at the "Reboot and select proper boot device" screen and even if I select my hdd to boot from it still takes me back to that screen. I have no idea what happened as my computer was running fine with no issues yesterday. I can't even get into safe mode.

Any help or advice would be greatly appreciated
