Quoting: Stellathe install trouble sounds very similar to my own Bazzite experience with the ROG Ally X, the Media Checker would get stuck at 4.8% and error out, and I could not do anything after that because it refused to let me use the iso because it was supposedly 'corrupted'. This is actually a known bug in the Fedora install media that's been present since at least 2016 (!!!) and it really caught me off guard. I had to connect a physical keyboard to be able to select the second GRUB option, that would skip the media check. Because of course the D-PAD did not work in GRUB. But after that, it went smoothly without a hitch.

This has been fixed since, the new live isos do not use media check, avoiding this problem altogether.
