Product: Pavilion 500 223w
Operating System: Microsoft Windows 7 (64-bit)
I decided to update the BIOS since I was having usb issues, and afterwards I cannot boot windows. It says: "Invalid signature detected. Secure boot policy in setup."

I tried turning off secure boot and clearing keys but it just bluescreens (stop 0000007b) during start even after hitting f8. It also sometimes has blank screen after bootgui.

I will probably end up having to reinstall Windows but I don't have the disc right now.
