AD Domain Controller Won't Boot

I run the network for a small organization. We have a virtual host server (CentOS) using VirtualBox to host the AD Domain Controller / File Server (Windows Server 2012). We recently had a power failure, and now I am getting an error on the AD Database (0xc00002e2) when booting. I have found How to fix Error 0xc00002e2 after rebooting Windows Domain Controller seems to be a good explanation on correcting the issue, but the local admin password I have doesn't seem to be correct. I have also tried restoring the server and creating a new install from a restore, but nothing seems to be working.

Our AD is replicated to Azure AD--is it possible to restore the AD from Azure? Is there another way to restore the AD without the DC local Administrator account? Am I up the excrement water canal with no source of propulsion?

Do you have only one domain controller? If yes, you should not; and this is why.
If your single DC doesn't work anymore, congratulations, you have just lost your Active Directory domain (unless you can fix it or you have a backup).

And no, Azure AD synchronization will not allow you to recover your domain; it's a one-way process, your AD rules over Azure AD when sync is enabled and there is no way to do the opposite.
