I’ve installed Fedora 34 as the only operating system on an HP Envy x360 15. It works fine if I can get to it!
If I simply power up I land on a frozen boot loader.
If I power up with Esc, the boot process pauses. Pressing Esc leads to the boot loader and a normal boot from there.
If I power up with F1, I land on System Information. Pressing Esc leads to the boot loader and it launches normally from there.
If I power up with F2, I land on Hardware Diagnostics. Selecting Exit leads to a frozen boot loader.
If I power up with F9, I land on Change Boot Order. Esc from there boots normally.
If I power up with F10, I land on the BIOS Setup Utility. Exiting lands me on a frozen boot loader.
And, finally, if I power up with F11, I land on a frozen boot loader.
I’ve been a linux user for several years at a more or less “advanced beginner” level and have used Ubuntu, Mint, and Fedora. I’ve never run into a problem like this! I would appreciate any help the community can render.
