Disk problem whilst attempting to install Buster (10.7)

[Peter Hillier-Brook <phb@hbsys.plus.com>]

Trying to install Buster to a new Acer Aspire A515-56. The install (from
live DVD) hangs asking for disk device ID. This info is at least 12
screws from immediate resolution, except for the BIOS(?)/UEFI output of:

HFM512GDJIN-82A0A for the HD

Is there anyone with direct experience of this hardware able to suggest
a way forward. For info, Windows 10 is pre-installed and appears to
function on whatever the disk is, although I haven't gone beyond the
attempted collection of personal data.

Thanks in advance.
