I have a HP Z4 G4 Core-X hat wont boo past the "Protected by HP Secure Boot Screen". I updated the BIOS to 02.74 Rev.A to try address an issue whereby when I restarted via Windows it would freeze on the same HP secure boot screen (press and hold power and short press power would allow machine to boot to OS)
I've done various things to get it to boot such as
1 Reverted BIOs to default settings
2 Run Diagnostics - all clear
3 Booted the machine with no peripherals attached
There is a warning in the BIOs logs regarding DIMM, see below.
Next step is I'll remove some memory and try get it to boot to OS.
FYI BIOs seem fine via F10 (I.e. not corrupted)
Solved! Go to Solution.

Yes it is listed as bootable. I also created a bootable USB to test, moved it to the top of the boot order and it wouldn't boot from USB. Same symptoms, just stuck on the HP logo.
I can try connect the disk to another computer, I suspect it will be OK. It just seems not to get to that stage of initiating the boot to Windows.
