I actually brought my laptop in from home, this I know is a uefi BIOS, on testing it, it booted into Fog with no issues ( it has been imaged in the past with FOG. So i then knew that UEFI boot was working. I have to hold my hands up on checking the HP 250 G7 it had not had secure boot switched off in the BIOS, this is a silly error and for this I blame my technician lol, (well i should have checked myself) on checking this morning i saw it was still on, I was lead down the FOG path after the kernel update failed. however i now have a different issue which i shall post.
