AMD Ryzen PRO 6860Z powered Lenovo Z13 notebook with Microsoft Pluton co-processor can't boot Linux operating systems

Phoronix reports that AMD powered ThinkPad Z13 laptop featuring Ryzen 6000 PRO Zen3+ series has problem booting Linux operating systems. This has been discovered by Matthew Garrett who shared the news on his website.

This laptop is equipped with Lenovo exclusive AMD Ryzen PRO 6860Z processor with built-in Microsoft Pluton security co-processors. This is a dedicated chip that is supposed to increase security for Windows systems by verifying UEFI certificate keys. The problem is that it only trusts Microsoft's key, not any 3rd party UEFI keys that are used by various Linux distributions.

This essentially means that Lenovo ThinkPad Z13 simply cannot run any Linux system. This laptop ships with Windows 11 by default and while there is no mention of Linux support anywhere, one could also argue that nowhere does it say it cannot boot Linux (and yes we have checked various official specs and press releases).

    Was only ever a matter of time.

    It started when Microsoft ended up having to sign all Linux bootloader keys with their key for anything to work, and it was always going to be a problem from that point onwards - through manufacturer apathy, if not malicious design.

    Fortunately the Windows ecosystem is getting ever-more irrelevant, and I'm literally converting MS PCs to Chromebook Flex machines as we speak (because even the users say that they only need a browser nowadays, and that it's SO MUCH FASTER despite being on identical hardware).

    I heard someone complain that Android apps aren't supported on Chrome OS Flex. Is that a beta thing or a Google control freak limitation?

    Otherwise, Chrome OS Flex seems like a great way to get lots of RAM since all Chromebooks on the market use soldered. I would like to know how well it handles weird configs like 4 GB soldered LPPDR4 + 32 GB SO-DIMM in empty slot.

    What is Chromebook FLEX?
    A search found me a lot of advertisements but little information.

      ChromeOS Flex, my error.

      It's basically ChromeOS, but made to run on ordinary PCs replacing their OS.

      Free, but you have to create an account to download it. It also works if you want to enterprise manage it with a normal Chromebook management licence, but that's not required for home use.
