Start M-Flash using the button in the BIOS settings or by restarting the computer and pressing CTRL+F5 (some use Alt+F5) during post.

If this is not set to UEFI the USB pen drive won't be read and you will get a black screen when entering M-Flash.

In the BIOS make sure the 'CSN/UEFI' option is set to UEFI.

Restart the computer and enter the BIOS.

Detach all USB pen drives from to the computer.

NOTE: There is no need to rename the folder or files in it.

This must use the FAT32 file storage format (though today I read that M-Flash will work with NTFS drives over 64GB too)
