Hello, not much of a Linux user (situations like this are why)…but long story short, I’m trying to rehab a ROG PC from 2018.
I made a bootable USB of the current Mint distro, but booting leads to a black screen. I tried compatibility mode, but the boot process hangs on “EFI stub: Measured initrd data into PCR 9”
The PC came with an Nvidia 2080, but it’s actually a 980ti. Also there isn’t integrated graphics here. Any troubleshooting advice would be cool


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
Ah, just saw edit2.
Are you saying that there are two options in GRUB one works and the other doesn’t?
If so, this is probably the easiest way: https://wiki.archlinux.org/title/GRUB/Tips_and_tricks#Recall_previous_entry
If it’s multiple options in a menu before you get to GRUB (i.e. there are multiple boot devices), you can edit the order with efibootmgr (https://wiki.archlinux.org/title/Unified_Extensible_Firmware_Interface#efibootmgr).
This will show you the boot options. You have to run this as root (using sudo)
This will change the boot order
You can remove unwanted entries with
Make sure you use the full 4 digit number and verify that you’re deleting the right one. You can add an entry back, but it is tedious to explain.
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.
You’re using GRUB: https://wiki.archlinux.org/title/GRUB
There’s a .cfg file in your EFI system partition, sometimes mounted on /boot. /boot/grub/grub.cfg has the settings for the items in that menu. If you can figure out what works about the recovery mode (it’s probably just launching with no kernel parameters), then you can edit the default one.
