Mint 21 works! I just got to the desktop environment…and guidance from here?
Edit: I went ahead with the installation. A clean erase and rebuild. The computer didn’t appreciate that. First restart took me to a hanging ROG logo. A second restart took me to GRUB then a black screen




Just to clarify, none of the options “work.” But ‘Advanced options for Linux Mint 21’ > ‘recovery mode’ gives me the option to ‘Resume normal boot’. And for whatever reason, that works when a normal boot (without extra steps) doesn’t.
