Question Selecting ''Discard changes and exit'' in MSI Bios causes Black screen A2 code freeze on cold boot

Selecting ''Discard Changes and Exit'' option in MSI Z97 Gaming 5 Bios causes Black screen A2 code freeze on next cold boot and BIOS Boot device into Windows Manager being Disabled on it's own.

However,
Selecting ''Save Changes And Reboot''option does not produce any Black screen A2 code freeze on next cold boot and no Boot device into Windows Manager being disabled on it's own.

I reproduce the problem 3 times just to be sure and I can verify that if you do not choose ''Save Changes And Reboot'' option in bios even if you are not changing anything but just browsing through the bios, the black screen A2 code freeze will come back. Not sure what is going on.
Anyone encounter or experience this sort of problem?




p.s. I fix the A2 Code freezing issue by unplugging and re-plugging all USB 3.0 ports (Keyboard And Mouse ) and the black screen A2 code freeze somehow disappears. It goes into normal booting sequence A2 -> 9C -> MSI Z97 Gaming 5 Dragon Logo Screen with delete button option to enter bios and boot back into Windows 10 normally.
