Tried booting LUbuntu instead, in the physical machine, from a USB drive made with Rufus. Both USB drives and the physical CD-RW worked and it was confirmed with bootctl that Secure Boot was on.

Tried booting a VM configured with Secure Boot. Pressed Enter again on the CD-RW entry and it loaded Windows.

Tried writing the iso to a CD-RW with Windows, with Verify on, and attempting to boot from the internal CD-RW drive by pressing F12 and Enter on the CD-RW entry: it just flashed the display once. Tried plain cp with another USB flash drive.

So what is going on here? If I have Secure Boot enabled how does MX boot? If not, why doesn't debian boot?Ĭp debian-10.2.0-amd64-netinst.iso /dev/sdbĭiff temp.iso debian-10.2.0-amd64-netinst.isoīinary files temp.iso and debian-10.2.0-amd64-netinst.iso differ One curiosity: MX indeed does not do Secure Boot as I just saw by typing bootctl in a live MX run. Going to the EFI setup, there is nothing like "enable or disable Secure Boot", there is only this menu entry:įorce System to Setup Mode - clear all Secure Boot variables (PK, KEK, db, dbx, and dbt). Following your instructions to set it up manually in a VM booted from the live debian iso while the USB drive made by Rufus is mounted (made in "ISO Image Mode", not "DD Image Mode"):Ĭp /run/live/medium/EFI/boot/grub圆4.efi. Its "DD Image Mode" produced the same error too. Created a bootable USB drive with plain cp (in a VM running the live debian iso):Ĭp debian-live-10.2.0-amd64-xfce.iso /dev/sdaįailed to open /EFI/BOOT/mm圆4.efi - Not foundīack to Rufus.
