HP Z440 Base Model Workstation
Microsoft Windows 10 (64-bit)

system is booting into manufacturing mode and it gives only 5 re-boots now. A refurbished motherboard put into HP Z440. Everything is the same, CPU, Memory etc as when it was booting before on the old motherboard. Won't boot into Win10, but working ok on Linux Ubuntu/Mint 20. But everything I tried, F2 then Alt F has not worked.

Very careful now with restarts because of Red error message says only 5.
