Scripting

I'm preparing to image a new Dell 3060 to windows 10 education while in UEFI GPT mode.  My understanding is I can boot to a Windows installation CD or USB if I add the CD/USB boot option in the BIOS.  Also, I was informed to create a UEFI GPT image, I would need to simply select UEFI over legacy in the BIOS and leave the Secure Boot option disabled so it could find the CD/USB.  My question is, I have seen threads indicating you will encounter the following message, "Windows cannot be installed to this disk, the selected disk is of the GPT partition style"  At this point, would you simply press Shit and F10 to open a command prompt and use diskpart to convert the GPT to MBR?  If so, once your done installing Windows to the MBR based partition and all your programs would you need to then convert the partition style back to GPT by using disk part again?  I don't want to convert to MBR and leave it that way and then SYSPREP to find out that I needed to convert back to GPT.  Also, I need instructions on how to create the windows installation CD/USB... can this be done from Microsoft's website using the Windows Media Creation Tool?
