Error encountered while loading the operating system.
I just got a used full computer and a motherboard, CPU, RAM package. I installed Ubuntu on an SSD and everything worked perfectly without any problems. The problem started with the motherboard I purchased. After connecting all the essentials—monitor, keyboard, mouse—I used the SSD from the finished build, thinking it would help test things. The OS started up fine and passed the memory test, but it keeps showing the Ubuntu prompt instead of continuing. I ran a memory test and it succeeded. It’s been running through the BIOS for a while now, and the CPU temperature has stayed below 40°C. Would a BIOS update resolve this loading issue? Is there something I’m overlooking?
I'm finding your text a bit unclear and inconsistent. It seems you're describing two motherboards, one with an SSD running Ubuntu and another with a bootable OS. On the second setup, the system boots but you can't launch Ubuntu. You're asking if what you mean is that GRUB starts, but pressing ENTER resets everything. If not, please take a photo of the screen just before it restarts.
Your points suggest you're trying to move an OS to a different machine, but there might be compatibility issues. Linux systems often handle hardware changes well, especially if they ship with the right kernel updates. However, differences in hardware like CPU type, HDD connections, or boot modes (UEFI vs Legacy) could cause problems.
It's usually safe to move the installation if it's similar—same CPU, same kernel version, matching device mappings. Sometimes missing kernel modules or parameters can cause issues during transfer. If you're unsure, check the bootloader settings and kernel configuration on both systems.
For testing, try booting a live OS from another device. In short: avoid moving existing installations unless you're sure, and always test on a fresh setup if possible.

I understand the situation, I’m not very familiar with Ubuntu. When I press enter to load Ubuntu it restarts, which resets things. I’ve used a different Ubuntu installation media and the boot priority ignored the disk. I plan to clear the SSD and try a Windows install to see if that resolves the problem. I’m not sure which OS was last installed, but Windows seems like a solid choice.
It’s simpler to attempt installing Windows directly if that’s your goal. If the MB is damaged, it will alert you sooner. Adjusting the BIOS can help skip the Ubuntu installation disk, but this only matters if you plan to install Ubuntu or test it beforehand. If you can’t boot, press F2 during startup to see if the MB model is correct.
