Impossible to boot with Omarchy Linux (and probably Arch)

[Denis_Leger]

When trying to boot with USB device, it ends with:
Launching EFI\BOOT\BOOTx64.EFI
Load failure (26) security violation.

Everywhere I read to disable secure boot. But I do NOT have this option! It is not under security, and not under boot neither. Also, please note I bought this desktop WITHOUT any OS. So No Windows 11.

After some reseach, it tells me to install Fedora or another distro… But really? Secure boot is enabled and cannot be disabled? I bought this computer precisely NOT to be annoyed by stuff like that!

I think I need help. Please could you confirm all my findings? Is there any way to disable the invisible secure boot in the BIOS?

Ok, found it thanks to this thread!

[SOLVED] EFI USB Device has been blocked by the current security policy

@Second_Coming I don’t see anything relevant in the Boot section. [IMG_20230609_010110] I tried disabling Quick Boot, setting a Timeout, Disabling/Enabling “Automatic Failover”, and setting “New Boot Device Priority” to other values, and rebooting still gives the same error. In case the instructions use a different BIOS version, I’m using InsydeH2O version IFR30.03.03.

Hope it will help other people. the thing is that this choice does not appear when boot fails and then when going to BIOS. You need to press F2 for the first BIOS big menu choices.

thanks
