Welcome to HP Forums,
This is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂
As I understand you need the correct UEFI boot order,
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:
Have you attempted to use the F5 on Bios to restore to defaults?
If you have and it didn't work, I recommend you check the below details:
The default boot order settings for the computer are configured in the factory. The default boot order for HP notebook PCs is listed below.
Floppy disk drive
Optical drive (DVD, CD-ROM)
Hard drive
USB device
Network adapter
NOTE:
An operating system not found error message may appear if a floppy disk or an optical disk is inserted into a computer that does not contain an operating system. If this error occurs, remove the disk and restart the computer.
If you have installed a second hard drive and the computer does not boot, please select the hard drive which contains the operating system as first boot device in the hard drive group.

I am an HP Employee
I have multiple Operating systems installed, each with their respective EFI file in the ESP (EFI System Partition).
For example: I have Windows 10 at \EFI\Boot\Microsoft\bootmgr.efi, and I have WinPE at \EFI\WinPE\Boot\bootx64.efi
When I boot into my BIOS I can see the list of operating systems, but I would like to be able to give windows a command to change the order and then shutdown, effectively telling Windows to boot into a different operating system.
