I have an installation of Win 7 on Rog Strix - which is not supported. I can't boot to it because the installation has 3.1 USB drivers that are not signed.

There is a rescue screen where you can turn off driver signing but I don't know how to get to it - a key to get to it may not exist because the OS isn't supported on this hardware.

My question is, how can I get to that screen, or, how can I talk to that installation and disable signing via cmd?

(The win 7 intallation is part of a 10/7 dual boot).

Thanks - rev
