I have an older desktop PC and I'm trying to do a fresh install of Windows 10. It is an HP P6710f. It has an SSD and a hard disk and was set with Windows on the SSD. I think it is a Legacy BIOS and cannot boot from USB, so I am trying to boot from an installation DVD. I have tried 3 different bootable DVDs and it always boots into Windows from the SSD. I've tried searching here and elsewhere and I keep finding threads that say to make sure the boot order is set to boot from DVD first, which is what I had already done.
Here is a link to photos of my BIOS setup:
