The root disk is the disk where / (root) gets mounted. This is also the
boot disk. There will created a separate /boot partition on this disk.
Select 'none' if you want have / (root) in memory only, i.e diskless or
data-only disk.

With a data-only disk you will boot from your current boot media (cdrom,
USB, CF etc) and run from memory only but have a disk where your data
gets stored. By default, there will be created a single lvm managed partition
where /var gets mounted.
Select 'none' if you want run completely disk-less.
