Need to Install a Backup domain Controller

I am trying to install a new secondary domain controller. When I removed the old secondary domain controller and had to use the /forceremoval option because I had errors trying to demote the domain controller.

I also had to force removal in active directory of the old domain controller because it was still in the domain controller group.

Now when I run dcpromo I can only install a RODC which I do NOT want to do?

I did install DNS on the new controller and it iw working properly as my secondary DNS controller.

How can I get my server to accept the dcpromo so I can install it as my secondary domain controller
