To confirm: My Ultra-45 would not boot from disk with a 100G root
partition. Reinstalled with 3.8G root partition (still ludicrously
large with a massive 2% used after install (/usr on separate partition))
and it booted from disk just fine.

The root disk there is a 465GiB (or 500 marketing-GB) SAMSUNG HD502IJ.

Looks like the Ultra-45 (and it's budget cousin, the Ultra-25, presumably)
can be added to the "can only boot from the first 4Gb of the disk" list.

Kind regards,
           Alex.
