In the case of a certain Acer BIOS, any attempt to set DefaultBoot will be overwritten by the default first drive, and if that drive does not contain the relevant code, booting will not occur, and another 'debian' entry will be added to the EFI table. The BIOS will continue to try to boot from the unbootable drive, and will add another EFI entry each time it does so. -- Joe
