I think I've done everything reasonable in my firmware to ensure booting by EFI. I have: Storage boot option control UEFI only Other PCI device ROM priority UEFI only (other options for both are "Legacy only" and "Disabled")
maybe this will help. Debian, and others show in GRUB, but not windows 10. HP workstation: I press F9 on boot for a boot menu I get a listing: UEFI - debian >other systems< UEFI - Windows Boot Manager It boots fine. Restart and I get GRUB, but without a windows option
The boot device is currently /dev/sdb which has a GPT partition table, and its first few partitions are number size mount point 1 953MB /boot 2 2GB / 3 10GB /usr 11 9GB /home 13 48GB swap 5 953MB unmounted, filesystem="grub2 core.img", flags="bios_grub" The first four are ext4. I do recall it was a pain to make d-i keep the GPT table not overwrite it with an MBR one. My motherboard is a Gigabyte H170 with 32 GiB RAM and I run Debian 12.8. I swear I ran a program that showed me EFI boot vars (if they exist) and it showed nothing. But now I can't remember what that program was. How can I ensure that I'm actually booted using EFI?
