I got instructions from Dell Support by e-mail that sorted it. I'm surprised that it's such a longwinded process!
Here it is for anyone else who has this issue......
1. Check in the BIOS (Press F2 at boot), to ensure the BIOS is currently in Legacy mode ( if the system shipped with Windows 7, the system BIOS it is most likely configured in the Legacy mode)
2. Boot from the Windows 10 recovery DVD (F12 Menu) (Legacy Option > DVD) then press the Enter key
Note: You may experience a delay (1 to 5 minutes) to boot to the Dell Screen with Spinning Circles.
3. Choose English
4. Choose US
5. Choose Troubleshoot
6. Choose Advanced
7. Choose Command prompt
8. In the Command Prompt Window, enter the Command: "diskpart" then press the Enter key (This will open the diskpart application in the command line mode)
9. Type Next Command: "list disk" then press the Enter key
10. Type: "select disk 0" then press the Enter key (0 usually is the target hard drive where the OS should be installed if there are multiple drives)
11. Type "clean" then press the Enter key
WARNING: ALL DATA on the drive will be removed. If you have any data you need backed up, abort this process and backup your data now.
12. Type "convert GPT" then press the Enter key
13. Type "exit" then press the Enter key (2 times)
14. Power down the System
15. Restart the system while tapping F2 key to enter the BIOS
16. Change the Boot List Option from Legacy to UEFI with Legacy Option ROMS "Enabled"
17. Navigate to Exit and "Exit Saving Changes"
18. Reboot and use the F12 boot menu option
19. Choose UEFI DVD boot option then press the Enter key
20. Dell Screen will show for a few moments
Note: You may experience a delay (1 to 5 minutes) to boot to the Dell Screen with Spinning Circles.
21. Choose English
22. Choose US
23. Choose Troubleshoot
24. Choose Recover from a drive
25. Choose either "Just remove my files" or "Fully clean drive"
26. Dell screen – will show "recovering this PC XX%"
27. The system will Reboot to Windows 10 when the installation is finished

Mikey0762,
Thanks so much for posting this. I've spent a couple of hours trying to figure this out, searching, etc. This worked perfectly.

This is exactly what I've been looking for (for "hours"). Worked perfectly.
