I swapped out the SATA drive on the Dell 5070. There is no NVME drive. Before I had a 256 GB drive. I put in a 1 TB drive and installed Mint on it. The previous drive also had Mint. But I must have somehow messed up the BIOS settings because now the blasted thing won’t boot.

The drive shows up on the System Info page of the BIOS:

It also shows up in the Drives page:

But I can’t choose it as a boot option:

Clicking on Add Boot Option only brings a error that it can’t find any file system. I tried restoring the settings but that didn’t help. What can I do?
