REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2823 Refer to UEFI spec 2.8, Section 13.3.2, a block device should be scanned as below order: 1. GPT 2. ISO 9660 (El Torito) (UDF should aslo be here) 3. MBR 4. no partition found Note: UDF is using the same boot method as CD, so put it in the same priority with ISO 9660. This would also solve the issue that ISO image with MBR would be treat as MBR device instead of CD/DVD. That would make the behavior of the image boot different: If the CD/DVD's MBR be handled correctly, it would be enumerated as a bootable device with MBR path and FAT filesystem. Some Linux Distributions boot from such path (FAT with MBR path for ISO) would come into the grub console instead of the installation selection. With this change, the CD/DVD would always be enumerated with CD path. And it would always boot to the installation selection.
