W11 Pro OEM not activating - also no key in the envelope
I've bought a Windows 11 Professional OEM. For reasons unknown to myself I could not start the installation from the DVD, meaning it didn't boot from the DVD. So I re-inserted my HDD with Windows 10 ...
When you inserted HDD with Windows 10, it was activated?
If you made a Windows 10 to Windows 11 upgrade, you must have digital entitlement, instead of your product key. This is tied to your Microsoft account. Signing in with same Microsoft account should have worked in this case.
But since it hasn't worked, you can reach out to Microsoft support:
