Some older versions of the BIOS don't play nice with GRUB2 (which Debian/LinuxCNC use). The BIOS must be upgraded, which can actually be done from within Linux. Here is the overall procedure:
* use an rEFInd pen drive to boot into Linux (despite it's GRUB2 not being fully installed)
* download the BIOS utilities .exe (sp58029.exe)
* extract the contents of the .exe using Engrampa or a similar archive utility
* inside the "HP Utilities for Linux" directory extract both "hp-flash-1.00-1_x86_64.tar.gz" and "hpuefi-mod-1.0.3.tar.gz". The resulting directories need to have paths that do not contain spaces, so if extracting them into the same folder as the archives, you must rename "HP Utilities for Linux" to "linux_util" or something containing no spaces.
* in the "hpuefi-mod-1.0.3" directory run <code>make</code> to compile the kernel module
* run <code>sudo insmod ./hpuefi.ko</code> to load the built kernel module
* run <code>./mkdevhpuefi</code> to create the <code>/dev/hpuefi</code> device
* extract "J01_0228.BIN" from the "sp71294.exe" self-extracting archive into the "hp-flash-1.00-1_x86_64" directory
* in the "hp-flash-1.00-1_x86_64" directory run <code>sudo ./hp-flash J01_0228.BIN</code>
* after it has finished flashing, reboot!
* after using rEFInd once again to get into Linux, fix GRUB with the following command: <code>sudo dpkg-reconfigure grub-efi-amd64</code>
