Not booting correctly

When I boot up my computer, It forces me to open a startup boot menu, and the only one I can select is Endless OS or “Advanced…” when I select Endless, lots of strings of code fly by and the loading screen comes up for about 3-4 seconds then it goes to a black screen any idea how to fix this?

Never mind, I had to go to advanced and choose choose an older version of the OS

There is a problem we’ve found with some graphics cards where files (cached shaders) written out by version 3.4 of the OS are not compatible with version 3.5, and this causes some systems to crash. We figured this out too late for 3.5.2 (released today) so we’ll fix it in 3.5.3 if we can, likely in January. Until then booting the previous OS version will work, or there might be a manual workaround that @daniel or @wjt could share.

We have released 3.5.3 today which adds a fix for this issue into the OS. Please update and let us know how it works for you.
