Makes sense, however, I thought Windows-8 and Windows-10 still had the "Anytime Upgrade" option and/or the ability to "change your key" so seems like there should be a way.
I've never tried what OP is trying. However, I have used OEM-replacement motherboards with a missing MSDM table, so I used the old key from old motherboard (as required in this instance). I think I also had to fiddle with the machine's "Default Keys" option in BIOS to get SecureBoot to work.
UPDATE: Got it working just like it was previously.
Steps I did:
1. Re-wrote the ISO into my USB drive with GPT partition table for UEFI bios.
2. Started setup in legacy mode and formatted C drive using CMD to GPT partition.
3. Installed Windows and rebooted.
4. Turned back on UEFI with Secure Boot.
There was another way of doing it without reinstalling Windows but it didn't worked because my C drive had 'Pagefile'. I tried to move Page file to Do drive but still it didn't worked. So, eventually, I had to do the setup again.
As for Rufus, just Google the directions. I think you would know if it was done improperly, because if not, you would not be able to clean-install Windows with it.
Be sure disk is completely blank and un-initialized (like it was just diskpart/clean-ed). If you have no other way, you can use the self-booting WinPE on Macrium Reflect Free v6.x flash-based bootdisk.
Set all your BIOS options properly before starting install (UEFI, SecureBoot ON). I like to only have the Primary disk connected at this point. Get it installed. Windows will initialize the disk as GPT, and create the required partitions.
After full build-up (First Time Setup and Drivers), run msinfo32. This appears to be the supreme SecureBoot check.
If it says that SecureBoot is still not Enabled, go back to BIOS and enable it. You might also have to use the BIOS option to restore the Default Keys or maybe some other option there dealing with the Keys.

Secure Boot only works with the Certificate in BIOS. Windows home is not the same as Windows PRO or Education.
You cannot Secure boot using a different certificate and country.
Legacy Boot is required. Secure boot requires the certificates to match.
Yours doesn't and wont.
Rufus is not supported by Microsoft or Dell and won't be.

No. As I posted the update, I got it working.
