"Windows 7 OEM marker present in firmware" means the BIOS has a Windows 7 OEM SLIC table. Which is a bit weird. That "model" motherboard must have shipped from Dell with a factory Windows 7 install at some point. There is no Windows 7 key stored in the BIOS, just an OEM identifier. If you did the free upgrade from Windows 8 the original motherboard got a generic key. The Home generic key ends in -8HVX7. If thats what showkey listed thats fine, all is good. You can clean install 10 Home with a skip entering a key and it will activate just fine with the DL it has now.
