I am having a problem disabling Secure Boot. I want to connect two additional SATA drives (Windows 10 and XP) and use the F-key option on boot to choose which OS drive to boot in to. That would make a total of 3 drives, W10, W7 and XP. In order to do this, I must disable Secure Boot in the UEFI.
Asrock has this remedial setup in the BIOS where the Keys in the Boot tab/Secure Boot must be deleted. They have an option to save the keys first to a flash drive so they can be reinstalled if I ever want to enable Secure Boot again. Thereby hangs the problem.
When I enter the “Save Secure Boot Keys” screen and click on it (with my flash drive inserted) a small screen pops up with the USB flash drive, and two other drives listed. I don’t even know what those other two are, I have only one SSD drive with my OS (Win7).
All I can get is a popup message, “Error While Writing To File”, and then a small, gray “dbx” lettering below that.
I assume the “dbx” is a hint as to what the problem is?
Please help. Thanks!
I didn't find the right solution from the Internet.
