    Yeah forgot to mention that I always manually selected the device to boot from when I was debugging this problem.

    The problematic backups indeed all had EFI instead of EFI- in the root folder. However, if I load the backup and then manually rename EFI to EFI- the resulting drive still refuses to boot.

    I just spent an entire night trying to reload my backup. I need legacy boot mode because previously I have experienced GPU passthrough not working in UEFI mode. However, the restored backup only works in UEFI but not in legacy mode. HOW TO REPRODUCE 1. Download a usb stick backup from Main > Flash Device > Flash Backup 2. On another usb stick, restore the backup using Mac OS Unraid USB Creator (Version 1.8) Local Zip option, selecting the zip file from step 1 3. Attempt to boot the new flash drive in legacy mode 4. Error message: Not a bootable device POTENTIAL WORKAROUND (Suggested by Frank1940) Use the flash creator to load a brand new copy of 6.8.3. Afterwards, copy the content of the original /config folder from your backup. If the USB Creator is not a reliable way to restore a backup until we find the cause, maybe we should update the documentation to mention this alternative method.
