Hmmm......not sure, but don't think so.
Do you have a flash drive to make the Win10 install media? You could use RUFUS to create the drive from the ISO, and it would be made for both Legacy and UEFI. Is there a specific reason why you have to use a disk? Although, it seems you are indeed booting to the disk, because you are getting the "Press any key to boot from..." message. Have you turned off Fast Startup? Are all those 200MB files showing in your recycle bin - have you emptied that? I can't tell if it's your current bin, or one from a previous installation.
