Our organization is upgrading computers to Windows 10. We use bitlocker, and newer computers require UEFI boot with bitlocker, so our imaging process changes the BIOS settings for this. I have upgraded several HP Probook 650 G1 to Windows 10 without issue, always updating the BIOS first, as the upgrade fails with an older BIOS. However, I have two HP Probook 650 G1 that have an issue once they went to Windows 10, and they have the newer BIOS versions 1.45 and 1.46.
The issue is, when you turn the laptop on while docked, it sits at the "Press the ESC key for Statup Menu" forever, no keys work, it never boots. If you shut the laptop down , take off the dock, it will boot fine, then can be docked. I have tried updating all the drivers, I have tried to cold boot the laptop (hold power down for 1 minute), and cold boot the dock, I cannot downgrade the BIOS, it always fails. I cannot see any settings in BIOS that I could change, UEFI boot order is OS Boot Manager. Could there be a problem with BIOS 1.45 & 1.46 using UEFI boot on the dock?

Hopefully, someone will come along with a solution for this -- but my suspicion is (based on my experience) is that is simply is not solveable -- IF you are using a USB-plugged dock, not a dock with a proprietary HP plug.
I ran into this same situation with a similar laptop that would try to boot from anything plugged into the USB port, no matter what it was. And, of course, if that was NOT bootable media, it would just hang there, indefinitely.
My only recourse was what you are doing -- waiting until after boot to plug in the USB device.
