The tutorial explains you to make a GPT format. The article will also describes the creation of an associated EFI system partition, which is required for an OS to boot in EFI mode.
Disabling legacy mode should enable booting in EFI if the hard drive and OS are set up in a GPT partition with a correct BCD file and EFI partition.
I would test this on a spare hard drive if I were you. I always do it that way to avoid nasty no-boot scenarios when experimenting with partitioning types. It gives me a plan "B" to fall back on, just in case things do go south.

Nope. Disabling secure boot didn't affect the BIOS. It did affect the hard disk. Here is a quote from a Microsoft web document regarding changing the secure boot setting in BIOS. There is a big downside and you have found it. It is time to recover your notebook to factory image by using the recovery media that you should have created by now.

OK. I should have read it a bit closer.
Secure boot should have been enabled as a default factory setting. It has been the case on my previous three HP loan product notebooks. That is the case in the BIOS settings found under Boot options in the BIOS of my current product loan Omen 15.
Enter the BIOS and go to system configuration. Locate and select load default settings. If that does not work then you will have to download the most current BIOS softpaq and run it on another PC. You will need to have a usb flash drive to install it to. Once installed to the usb flash drive, you can plug it into a port on the notebook with the issue and boot to it to recover the BIOS on the notebook. Recovering the BIOS will return the settings to default and should make the hard disk viewable on the boot list again.
The problem you were having is that the BIOS was previously set to look for an EFI sector instead of a MBR boot sector, which it would find in a MBR partitioned hard disk. Your hard disk is GPT partitioned and the bootable partition has a UEFI marker.

If you use the recovery media, it should install the operating system in GPT format.
The notebook did not load Windows 10 instead of the original operating system without your agreeing to it.
Is your notebook still in warranty?

So you are after an explanation of how to set up the notebook in GPT format so you can dual boot?

If the issue is that it still has BIOS issue, you can download the PC Hardware Diagnostics UEFI from the following page, install it to a usb flashdrive and put the BIOS 0183AF26.bin file in the HP_Tools folder. Look at the Windows 8 drivers to find the BIOS update softpaq file.
Boot to the PC Diagnostics flashdrive and use the firmware management utility to flash the BIOS. That should resolve the no boot issue you are having.
Once you do that then I will find you some information on GPT format.
The problem you will run into, is that your Windows 10 instalation is likely to be using the license that your notebook was delivered with for the originally onstalled OS. You will need seperate licenses for the other operating systems.
