OS Boots on one device but fails to boot on another (mander.xyz)

Hi, I just did my first Linux install (Kubuntu) onto an external NVME drive. It boots fine on my laptop but gives me a "MBR error, insert floppy" screen when I try to run it on my desktop. On the motherboard settings the drive shows as a bootable option but without a UEFI label. What issues could cause this? From what I've read it seems like a boot loader problem but I have no idea why it would be fine on one device but not another. I tried to update the motherboard firmware but the file the manufacturer provides wasn't working. It's running a 2021 version.

In the bios options it shows that secure boot is already disabled. It's not an old pc. I got it around 2021. Z590 motherboard. I've already run a system image off of a USB drive, which is how I installed the OS originally.

Hmm. I did have one machine that would install from USB but would not boot after. Turned outbit was a hardware glitch deb and deb derived distros could not get past, so I found RPM based worked fine as did NixOS (weirdly)
