What happened?

I'm using QEMU + OVMF to test images

after selecting what to boot, the (internal) grub says:

error: bad signature.

Press any key to continue...

after some second it just continue by itself, but Linux fails to identify the root block device Spawning a shell I see sda and sr0 in /proc/partitions

I cannot mount sr0 because it says no medium found

I'll try booting on bare metal

sherpya commented 2 years ago

even worse on bare metal, I cannot press a key and the boot hangs there

this is my script to launch qemu

#!/bin/sh
CODE=/home/sherpya/ovmf-x64/OVMF_CODE.fd
VARS=/home/sherpya/ovmf-x64/OVMF_VARS.fd
exec sudo qemu-system-x86_64 \

@ventoy it would be possible to inject a replacement /boot/grub/grub.cfg before starting grub?

ventoy commented 2 years ago

grub.cfg is also signed and will be checked when boot.

sherpya commented 2 years ago

I used to make a sort of ventoy but only using vanilla grub, many iso are just bootable by grub with some trick, I was loading it directly, the only problem was the version I used insisted to have the iso in /data directory. Anyway you may overwrite the efi shim with ventoy efi grub :D

if there are no cleaner solutions you can just close this issue
