Can someone point me to a spec or something that defines waht a valid uefi boot device is?
background: I use the hd-media image (becuase it is a fat fs so I can mount and edit kernel boot parameters) but hd-image is not efi at all (it doesn't even try.) I have an MR that addresses it but needs work: https://salsa.debian.org/installer-team/debian-installer/-/merge_requests/7 The post is related, but new as I just now found an HP server that won't boot my patched hd-media. and I am compelled to figure out what correct is. What I did figure out: fdisk /dev/usb-stick, create 1 partition. dd the hd-media.img to the partition instead of the host device. The HP likes this. Once I find a good description of what the efi spec is, we can talk about making hd-media efi. -- Carl K
