Package: grub-efi-amd64 Version: 2.04-20 Severity: normal I am in the process of making a diagnose & manteinance Debian setup onto a USB stick that can boot in whatever PC drops in my hands. Working on having a custom EFI boot entry I encountered that adding the --bootloade-id option in grub-install makes the system boot into the GRUB console instead of the usual GRUB menu. Not GRUB rescue, the regular GRUB console.
I can get in there by manually bring it up with the following GRUB commands: set prefix=(hd1,gpt3)/boot #or whenever /boot/grub resides insmod normal normal I tried almost all combinations of adding --recheck, --no-nvram and --removable, but it seems that it the route isn't EFI/debian or EFI/BOOT the system won't boot on the menu. Weird enought I copied grub.cfg into EFI/[custom-name] and it seems to work, but the frame of the menu is compsided of the unknown square unicode character Currently testing on a MacBook Pro 9,2, did some test on a brand-new Lenovo L340 -- Package-specific info: *********************** BEGIN /proc/mounts /dev/sda4 / btrfs rw,relatime,ssd,space_cache,subvolid=256,subvol=/@rootfs 0 0 /dev/sda3 /boot ext4 rw,relatime 0 0 /dev/sda2 /boot/efi vfat rw,relatime,fmask=0077,dmask=0077,codepage=437,iocharset=ascii,shortname=mixed,utf8,errors=remount-ro 0 0 *********************** END /proc/mounts *********************** BEGIN /boot/grub/grub.cfg # # DO NOT EDIT THIS FILE # # It is automatically generated by grub-mkconfig using templates # from /etc/grub.d and settings from /etc/default/grub # ### BEGIN /etc/grub.d/00_header ### if [ -s $prefix/grubenv ];
