So hello again mglae, unfortunately your links did not work, you made a mistake when posting the links I guess: NVM
What I tried:
- BIOS Update to the latest one ⇒ did not change anything
- Installed Nightly Build ⇒ No Changes
- After that i Did
- HP has a Boot timeout I, have set that to 5sec.
- disabled Quick Boot
Now, LibreElec seems to Boot normally without any issues… Currently.
Will do some Testing with the System^°°
THX for your Support Guy's, I Appreciate It.
EDIT: Solution finally was, Disable Legacy & Secure Boot
