HAOS on hp prodesk bios problem

Installation Home Assistant OS
1

Hi everyone I’m not an expert my I usually can manage how to do things.
This problem is blowing my mind.
I bought a prodesk G2, I followed the instructions and I installed HAOS. Everything should be fine, but my PC won’t boot.
“Selected boot image did not authenticate”

I know I have to enable legacy support and disable secure boot.
My pc seems not to let me save these options. If I set it as I should and then restart and get back to the bios options page, they are back to legacy support disable and secure boot enable.

Any idea of what else I should check/uncheck in the BIOS?

Thanks in advance.

I used to have a HP laptop that did this, from memory I had to:

Enable Legacy support only. Save and restart.

Go back into BIOS then try disabling secure boot. Save and restart, then check to see if it stays.

I don’t have the laptop any more so I can’t check and see if it works for a HA install.

Thank you very much for your hint.
Unfortunately my BIOS has one line for both options

“Legacy Support Disable and Secure Boot Disable” is the option you need to select/ save. Wich translates as UEFI=on, Secure_Boot=off.

Bummer. Hopefully someone else has a more useful suggestion…

I tried.
I actually tried all of them.
But the main problem is that it seems it doesn’t save the settings, because every time I enter the BIOS after saving and trying to boot, that line is back to “legacy disable - secure enable”
:sob:

There was an issue with some. Hp rigs where they didn’t do something correct when you hit one of the bios entry key sequences and it didn’t do something correctly (all from my head sorry)

Short version there’s two key sequences to enter the bios f10 and f12. Whichever you’re using try the other one. One of them doesn’t prompt for some code correctly and the net is not saving the settings when you exit. Sound familiar?

Thank you. I didn’t notice a second entry to the BIOS even though I spent hours in front of it last night. :sweat_smile:
But I’m definitely going to try tonight again, thanks for your tip.

Hope it works. I just remembered something weird about those HPs and a quick check if the internet you’ll show a couple of posts in other places that align with- your model Bios, won’t save. They don’t call out your model number specifically but man it sure sounds like what you’re describing… Also weird. Also…

Dude I’m getting a Dell. Or a NUC :rofl:

Worth trying to see if there is a BIOS upgrade.

Sometimes the BIOS battery is worn out and whenever you reboot the BIOS resets to factory defaults.

It is usually just a coin cell battery that can be easily replaced.

And to help you with the BIOS settings, then legacy support is refering to the compatibility module for old BIOS drives.
When it is enabled the BIOS work with both UEFI and BIOS drives.
When it is disabled it only works with UEFI.

Oooops I feel so stupid, but I finally realised what was wrong.
After setting up my BIOS settings it rebooted and asked me for a 4 digit number to confirm the changes. I always inserted those 4 digits without the numpad active, since it just restarted, so it never saved the settings! Such a stupid way to waste my time!
And as I was trying new ways to do it, I skipped through the 4 digit thing faster and faster, never ever realising my mistake! Until now.
I left it aside for some days, because I had some other stressful things from work to think about, and now I’m back on track! Just saved the settings as legacy disable and secure disable and it’s running!! :joy:
Thank you everyone for your help, very appreciated! :+1:t2::+1:t2:
