12.04 installation shows the intended target partition as being 12.8GB when it is 128GB. I created the partition with Win 7, but did not format it nor assign it a drive letter.
This is a new Lenovo Thinkpad in compatibility mode (not AHCI) and not secure boot?
This target partition is the fourth, taking up the last 128GB of a 500GB disk.
I'm certainly not going to install before figuring out where the inconsistency is.
