I have a DELL ONE 2020 which came with Windows 8. I no like 8. Soooo....I went to install 7, not realizing it was an upgrade install until it was too late... I had already wiped it clean. ... Yes I can hear all the why didnt I copy iso. Boils  down to I just couldn't figure out how to do this. So now I have a blank harddrive in a fairly new pc so I grab an old xp install and off we go ...thinking  I will then use the upgrade to get Windows 7 installed.  but every which way I have tried . I get the "No  boot manager found" error of cousre this Dell has the UEFI/Legacy feature which I have worked with before,   any suggestions out there?

You should be able to do a clean install with the upgrade media. Make sure SecureBoot is disabled in UEFI. If there is a Quickboot/Fastboot setting in UEFI then disable it also.

If you still cannot get the install disk to boot then use Imgburn on another computer to create an iso from the install disk then use the iso with Rufus to create a bootable USB flash drive. I would use a read speed no faster than 4X if possible when creating the iso image.
