/!\ Warning /!\

The tests were mainly done with Ubuntu for testing. Tails is also mentioned.

Both Tails and Ubuntu contain nonfree software:

H-node isn't a database for compatibility with distributions that are not 100% free software, but here the goal is not to document compatibility with distributions that contain nonfree software but instead to document if this computer has restricted boot or not as we could not boot any installer on it yet. So it looks important to investigate because it could really be have some form of restricted boot as it has no ways to boot an installer.

If for some reasons, h-node is not the place to document that, and that this computer has no restricted boot, an article could probably be written to explain how to boot FSDG distros installers on computers like that, and the entry could be either removed or updated to remove references to nonfree distros once FSDG distros or installers have been tested on it.

If for some reasons, h-node is not the place to document that, and that the computer either has restricted boot or that we still don't know if it has restricted boot:

This is a desktop computer. We tried to install GNU/Linux on it at an install party. According to what I was told that computer had Windows 11. I'm also not the one that read the computer model on the computer but it correspond to pictures I found on the net.

And in these 2 cases, the UEFI has no options to boot on USB devices. It only show the internal HDD or CDROM drive as boot devices. We also can't add USB boot devices.

With ubuntu-22.04.1-desktop-amd64.iso, the USB key is recognized in Windows, but it's not seen in the USB devices in the UEFI, through the UEFI sees the keyboard and mouse. ubuntu-22.04.1-desktop-amd64.iso should support UEFI secure boot. debian-11.5.0-amd64-netinst.iso was also tested.

Tails has a very good manual that explains how to boot a GNU/Linux installer (someone probably needs to do an FSDG compliant version of it as Tails contain nonfree software).

In https://tails.boum.org/install/windows/index.en.html#restart there is the following picture: https://tails.boum.org/install/inc/screenshots/choose_an_option.png

When following this guide (with Ubuntu), the "Use a device" menu wasn't there.

So we can't validate if this computer has restricted boot or not but it looks like a really good candidate to do more in depth tests.

Though it could also be meant for business customers that don't need to boot installer on USB keys, but instead rely on network booting or PXE.
