You most certainly can. My Z90 (essentially the same machine -- AFAIK the
differences are that it came fully assembled ('Z', not 'H'), and came
with 64K RAM, has MTR-90, the hard sector controller and the
double-density soft sector controller. The former is cabled to the single
built-in drive, the latter to an external drive box.

It will boot either HDOS or CP/M, and can use both types of disks
