Help installing Linux Mint on my Dell OptiPlex 7090 SFF
I am trying to install Linux Mint 22.2 (w/Cinnamon) on my Dell OptiPlex 7090 SFF.
When I go into the boot menu and set the computer to boot from the USB boot drive, it simply locks up at a black screen when it tries to boot after the Linux boot menu. When I select "compatibility mode" instead it gets just two lines into startup dialog and locks up at that same black screen.
I've used the install USB drive I created to install it on an old laptop first as a test, and it worked well, so I know the drive itself should work.
There's probably some settings in the BIOS menu I need to change, but I can't imagine what. I disabled Secure Boot, in case there was a problem with that, but that didn't help.
Can anyone please assist me in figuring out what I need to do to install it on my computer?
(Ideally I want to set it up for a dual-boot with Windows 11, which is already on the computer, and Linux Mint 22.2, but if that's not feasible I will just set it to Linux only).

Hi
It will install with/without secure boot.
What it wont do is accept a Legacy/MBR stick to match a uEFI install or vice versa.

Install little bit older Linux to install new one - interesting.

Linux Mint 22.2 may not be a supported operating system. It does support Ubuntu 20.04 LTS. Link goes to supported operating systems.
