Z77 Extreme4 p2.90Q wont boot uefi usb

Booting from another device and trying suspend-to-ram mode shows that the i750 device does not come back properly.

After using UBU to update the integrated RST blobs (also did the integrated graphics blobs and latest microcode updates), the system now resumes from sleep.

For anyone trying NVME+Asrock z77 extreme4, consider trying the attached bios. As usual with these sorts of things, your hardware, your problem if anything goes wrong.

	I broke my bcd file and have been trying to fix it but nothing was working and then I found to fix I had to boot with a uefi drive. I swapped out my win7 recovery disc for a uefi formatted by rufus usb but it wont boot it. If i select the uefi: usb stick option it just flashes the screen and nothing happens. If i select usb: usb stick it says theres nothing on there! Why wont the asrock uefi setup utility open my uefi bootable media?
