Hi mrbrklyn,
TheOldMan has replied to your question Z2 g9 linux installation in the
HP Support Community.

Subject: Re: Z2 g9 linux installation

While I have not actually had to work with Wolf Security system before,
it is set-up to prevent such an activity as loading an OS different from
Windows.  It is not impossible but you need the manual for from HP to
see the procedure on "How to" get started. Since Windows is already
loaded, you can go to the support site Official HP® Desktop Drivers and
Software Download | HP® Support Scroll down to the "Let HP detect your
product" and then follow the prompts to get to the proper support page.
Look for the Maintenance and Service Manual . Here is a guide for Wolf
Security HP Wolf Security User Guide
