Hello there,

Your machine’s BIOS version is the lastest.

Please try this tutorial to solve the problem: https://buildin.ai/lizong/share/262ce514-3f67-4324-8127-9962a33b1d4d

The security certificate update for Windows can be resolved by attempting the March Windows update and then installing the latest version of Windows 11 PRO.

Have a nice day~

Hello there,

We have already passed your issue on to the developers for their attention.

At present, the problem with your machine requires the installation of a new BIOS.

Hello,
I believe I have a similar situation going on here as well with regards to the BIOS 2023 certs but on the SER8 8845HS:

System- SER8 8845HS S/N: B88455HF80235 OS:Win11 25H2
BIOS: V035.P8C0M0C15.14

(This was the latest BIOS as found on the support page at the time and used because there was no Secure Boot option with the original BIOS received with the unit.)

My system has gotten a little farther with regards to installing the 2023 Certs and Boot Manager. I have forced, via registry update, to have the boot 2023 Certs installed as indicated by the Event log ID 1808 posted below. Unfortunately, it has not progressed past this point to update the bootmgfw.efi files. The Event IDs 1044 and 1045 have occurred, but none of the Event IDs 1043,1034 and 1799 have occurred. The bootmgfw.efi is still signed only by the 2011 cert or the Event ID 1799 would be logged. I have attached the Event ID 1808 full details below which still states that the final updates are “Under Observation - More Data Needed”. According to the Microsoft data, this indicates that the BIOS could be holding up the update. Is the BIOS still holding up the updates, or is Microsoft holding up the update because the SER8 BIOS is not on the approved list yet? Any direction on how to proceed would be appreciated, because I would assume others are going to have this issue as well.

Kind regards 😉
