If a user defines BootNext but not BootOrder and loading from BootNext fails, you will see only a message like this: BootOrder not defined

This may confuse a user. Adding an error message will be helpful.

An example output looks like this:

=> efidebug boot add 0001 label1 scsi 0:1 "\path1\file1.efi" "--option foo" => efidebug boot add 0002 label2 scsi 0:1 "\path2\file2.efi" "--option bar" => efidebug boot add 0003 label3 scsi 0:1 "\path3\file3.efi" "--option no" => efidebug boot order 0001 0002 => efidebug boot next 0003 => bootefi bootmgr Loading from Boot0003 'label3' failed Loading from BootNext failed, falling back to BootOrder Loading from Boot0001 'label1' failed Loading from Boot0002 'label2' failed EFI boot manager: Cannot load any image
