If you're planning on using Linux on it, it installs just fine. If your distribution of choice is Ubuntu, avoid 22.04 as it is unstable on this system, and go for Ubuntu 22.10 (or any other more recent release if you're reading this at a later time).As for Windows, you can't reinstall with Microsoft ISO (22H2 I believe I used). It will notify you that it is missing a driver to install prior to starting the installation as you can see on the screenshot. Unfortunately, it isn't specifying which driver is missing.I first tried different steps to go around the issue that I found online, which among other things suggested different thumbdrives, checking BIOS settings, to no avail. I went through Beelink website, and tried the drivers packs for this system to no avail (trying every single driver in them).I then contacted support, which made me run around, just to be told after more than a month of back and forth that they don't have the missing driver(s). Their support take multiple days to answer, sometimes a week or more, and doesn't read carefully the emails, resulting in having to repeat a number of times that my issue was prior to Windows being installed (so their guide didn't apply).They asked me to provide multiple screenshots of BIOS, installation, serial numbers, purchase number and I had to keep telling them the issue I have was while trying to install Windows as they kept providing me guides that were for Windows while it is installed. They had suggested at one point the missing driver is from the SSD, but the manufacturer, Kingston, had none available.While they have an ISO you can use to reinstall Windows 11, that you have to download from mega.nz (I'm not even sure they provide it on their support site), it's the one they build themselves, which I don't like. I do believe you should be able to install with the ISO from Microsoft (which I have been able to do on all my computers since the 90s as far as I remember), and, in this case all, the one (or multiple) missing driver(s).
