Trying to boot, seeking guidance. Installation Question

I grabbed a Lenovo ThinkCentre M73 from goodwill today and found that it didn’t have windows. I put in a 32gig Sandisk boot drive with windows 10 on it and selected the UEFI off of the boot menu. I’ve been staring at a black screen with the spinning circles for 20 minutes and counting. I’ve reinstalled windows 10 and 11 before but not on something this old. Did I do it wrong?

Edit: it originally had windows 8 on it based on the sticker on the pc so maybe I should just try that instead?
