Setting up myNode on HP Mini PC

I'm trying to get myNode to work on a HP Elite Desk 705 mini PC. But when I boot from the USB, I keep getting this error: "Selected boot image did not authenticate". I’ve already tried two different USB drives, both made with Balena, using the image I downloaded from the myNode site (PC Image / Model Two | Download v0.3.24 (amd64)). Any suggestions? Thanks, friends!

Get into the BIOS of the machine and turn off secure boot. https://support.hpe.com/hpesc/public/docDisplay?docId=c04398276&page=s_enable_secure_boot_enforcement.html&docLocale=en_US The above HP link may or may not be exactly for your PC but it's somewhere in there. -Dave

OK that did it! This is what I had to do on the HP for anyone who finds this in the future: 1.) Hold the ESC button to enter bios 2.) Press F10 for settings 3.) Go to advanced tab and select Secure Boot Settings 4.) Select "Legacy Enable and Secure Boot Disable" 5.) F10 to save changes 6.) HP will then prompt you to type 4 numbers and confirm.... note you need to use the numbers above the letters on your keyboard not the pad. 7.) while it reboots hold ESC to get back into BIOS 8.) Select USB to boot from
