Hello,
firstly - you assumed right.
But as I hope, I mentioned before, the conventional ways to do things don't cover my case for some reason.
Therefore:
Regarding the Chapter 11 of user guide: That absolutely doesn't reflext what's going on in that settings. There is no option to do anything about secure boot.
What I found on the internet was a different approach. It was to go through something like:
PC Settings ... -> Troubleshooting -> ... -> Restart to change UEFI settings.
That don't work for me either. I see the settings all the way, but when I hit Restart, or OK or whatever, I'll get the computer restarted. No settings.
But!
During one of my previous unsucessful attempts I installed an app from HP, I believe, that adds a configuring application for "BIOS" and there I can change the boot order and set up secure boot.
Which I did, obviously, but I don't think it has done any difference.
Like I said, it's hard for me to guess, what piece of the puzzle is broken, so I don't want to point fingers. But I still believe, that I have the setup right, but everyone and every manual out there is missing one thing to setup.
No reason to think that, sure, it's just my experience with this sort of issue. So...any ideas?
About the boot order.
You might be surprised, but the user guide again doesn't reflect what's going on. And yes, your feeling that I don't really like user guides is not a feeling.
Anyway, I can succesfully load up the "what I'm going to boot from". Which I consider pretty stupid, since I've set up the boot order in the tool from HP, plus it was working like that for at least 20 year not...but anyway.
I load it up and it only offers me something like "Bootloader OS"
That happened to me before, but I was thinking that it's due to the secure boot. And again. No reason to think that.
But!
This time I used a different USB stick, and it was glowing while booting, that means that the tablet can work with USB's in the jacket
Anyway, if you have any ideas, I'm all ears.
Thank you
Jan
