Machine ran fine (windows 7) before wiping the hard drives. Thing is, I couldn’t access the boot menu to install a new OS via thumbdrive because the display cuts out when I get there, and I’m 1000% sure HP did this on purpose because I’ve seen other people experience the same issue in forums and videos even after verifying each individual component worked and that the setup screen still functions. I theorize whats happening is the boot menu is running normally but they have it cut the feed so that only trained HP employees know what buttons to press in what order. Ctrl Alt Delete during this phase restarts the machine, and accessing boot menu before wiping then pressing enter booted like normal.

(one of the damn things are locked up like Alcatraz btw, rivets in the case, had to wire it to another computer while leaving it in the original bracket)

But after installing Windows 10 LTSC onto the drive it still doesnt finish booting, and with no display output it’s hard to know whats going on.

I could try some Linux distros with compatibility in mind if I get any suggestions.

Whats next to try?

UPDATE 7 OCT

Things I’ve tried so far:

  1. install linux mint from USB

Result: Failure/No Response

Cause: Unknown

  1. Installed a bootable linux mint to an EFI drive partition on the hard drive using a second computer then installed that drive on the machine in question.

Result: Failure to boot

Cause: Unknown

  1. Burn a Hirens BootCD and use Plop Boot Manager to make bootable USB usable and potentially enable some graphics

Results: Pending, I didnt have any CDs/DVDs large enough to burn Hirens

Here are some Images of the BIOS Setup screen at default values except for Diagnostics and boot priority.

Notice the USB drive is listed alongside the unallocated hard drives.

UPDATE 7 OCT #2:

Walked away for a snack and came back to this big beautiful screen!

Now clearly it has managed to get past the boot menu to Linux Mint. Mouse is responsive.

This is a very unsatisfying conclusion, because I do not know why it works now but did not work before. I don’t understand.

UPDATE 7 OCT #3:

PS This machine appears to be 32 bit only, despite the 64 in the processor’s name, so the mainline Ubuntu distros don’t support it, but I was able to get an MX XFCE running.

    It’s already connected via VGA from the motherboard (this device has a card in the PCIE slot that I’m not even going to bother with). This is a desktop not a laptop, as are all the m8000s, all peripherals are external.

    Right now I’m trying to install Linux Mint onto the HDD then plugging it back into the machine, if that fails I will try to make a Hirens BootCD and then see what I can do from there (it has a CD Drive, and as you mentioned probably doesn’t support booting from Thumbdrive).
