Public bug reported: Where to start. Apparently the iso (ubuntu-mate-20.04.3-desktop- amd64.iso) assumes every computer runs Windows and has small disks (2 TB or smaller). The "Disk Image Writer" formats the jump drive as MBR with bootable partition, a EFI partition for Windows compatibility and the rest of the drive (59GB) as unusable.
I purchased a 1TB WD Blue SATA SSD and tried to install in it. The first five times failed. The drive was initially blank and the installer disabled the Install button. I used 18.04 Disks to creat the GUID partition table and create the UEFI System Partition, the Ubuntu MATE partition, the Linux swap partition, and a NTFS data partition. I was at least able to start the installation. Then the installer crashed.
