Windows 7: Installing Win 7 off a USB, "Legacy Support Disabled in the Setup"

Installing Win 7 off a USB, "Legacy Support Disabled in the Setup"

Ok, so recently my PC kind of gave up. It's been crashing irregularly, so I'd been preparing to reinstall, but my preparation was cut a little short by my PC now not even getting past the login screen. Anyway, I have a Windows 7 installer (64 bit) on a USB, I changed my boot settings to boot from USB first, and I'm getting just a black screen with the sentence "Legacy Support Disabled in the Setup". I checked the BIOS and Legacy USB is enabled, and I know disabling it will disable all my USB ports, and I don't have a PS/2 keyboard.

Any help would be hugely appreciated.
