Bootme flags are non-standard and have been ignored in UEFI since the start. I read the man for efibootmgr but it was way above my pay grade :-) I tried add/create but got nowhere. store-08# efibootmgr BootCurrent: 0000 Timeout : 0 seconds BootOrder : 0002, 0000, 0001 Boot0002* Broadcom NetXtreme II Gigabit Ethernet (BCM5709) +Boot0000* EFI Fixed Disk Boot Device 1 Boot0001* TSSTcorp DVD+/-RW TS-L633C At some point I succeeded in deleting the dvd, but now I see its back. So how do I add a second boot partition? (If the sequence look fishy, it’s because I can change the boot sequence via DHCP) > > Or better yet, use boot environments.
