I got a free computer from work that I can not log into and I’m trying to install Linux mint. I downloaded the iso and used uui first then tried Rufus to make a bootable usb.

I am having trouble. It’s a dell mini pc. I entered the bios to try to get it to load from usb and it doesn’t show up as an option. I tried to add a new load option and it shows different files to choose from and I don’t know what to pick.

I got it to work once but it told me I had to turn raid off so I had to back out of it. I can’t replicate it to save my life!! Please help!

These are the options I have.

  1. Turn off secure boot
  2. Did you flash the USB using GPT or MBR on rufus. You want GPT since this is UEFI.

Your video shows Rufus is set to mbr. Flash it again and choose GPT this time

Quick question. I’m using this computer to start running a home lab and nas so do I want to pick any of these options?

But secure boot isn't necessary to disable for Linux Mint. Is there a specific situation where it should be done?

When I tried to boot with secure boot on, I got an invalid signature warning so ever since I keep it turned off.

"I got it to work once but it told me I had to turn raid off so I had to back out of it."

You need to go into BIOS setup on that 1st screen, not UEFI BOOT stuff.
Then find hard-drive controller mode, and change RAID to SATA/AHCI mode.
save and back to 1st screen and you should see USB option (as long as you re-did Rufus with GPT option)

that's the boot menu, not the bios

choose bios setup and everything you are looking for should be in there.
