I lost my only on premise DC without backup and need help

Question

Hi
I created a DC on Virtual box and was practising on it for the last year.

I also joined it to my cloud Azure domain using AD Connect.

Unfortunately, I was trying to clean up my Hypervisor files and accidentally deleted an old snapshot from the VM folder and now the VM cannot start.

oddly enough I had another copy of the VMs on an external HDD but that whole HDD was corrupted somehow (my luck).

also, I tried some recovery tools but the files that I recovered didn't work either.

I need help to understand what can I do to create a hyper environment again.

1- can I somehow with some effort rebuild the on-premise DC using the data from my Azure AD?
2- if this didn't work can I delete my old DC configuration and accounts from Azure AD so I can create a fresh DC on-premise and connect to it again.

good thing that it's only for my practice but now I don't know how to make it work again so I can continue my study.

Thanks

As far as the on premise is concerned from what you described you'll need to build out a new one. Also note it is always recommended to have at least two domain controllers for high availability and disaster mitigation.
