We have an HP 830 G6 with a bios password that we forgot, it refuses to boot to Windows. It's our 1st HP after only using Thinkpads we're much more familiar with even 1 with forgotten password but it still boots to Windows fine. So question is: what is preventing the system to just boot to Windows on this HP when my Thinkpad (T470s) boots to Windows no problem not caring about bios? Are the systems that different?
