Hello @schmalgausen
Well, we have to switch to the HP Diagnostics UEFI variant, which is independent of the Windows operating system:
(1) Download and install
HP PC Hardware Diagnostics UEFI | 8.7.2.0 Rev.A | 62.4 MB | Aug 21, 2022 | Download |
(2) Run HP PC Hardware Diagnostics UEFI
https://support.hp.com/us-en/document/ish_2854458-2733239-16
See section <Running HP PC Hardware Diagnostics UEFI tests when Windows doesn't start>
See how it works:
