Hello Jessica,

Looking at the script you've used and seeing the error you're getting, I
can't say for sure where the culprit is, but could suggest some
troubleshooting steps.

The error _appears_ to be a problem loading bootmgfw.efi. Wimboot can
extract that file from the WIM (unless you explicitly provide it as in your
script), so try commenting out or removing the line:


...and see what happens.

It would be a good idea to rule out this system's firmware as being the
source of the problem as well. Do you have any other UEFI machines you can
try booting with the same payload?

Best regards,
