I had the same issue. Restart services for SMS_EXECUTIVE (SmsExec) and SMS_SITE_COMPONENT_MANAGER (SiteComp). The MDT buttons didn’t appear in the console until this was done.
Also, check for and confirm the presence of “Microsoft.BDD” DLLs, XML, and MOF in these locations, per the ConfigMgr Integration output log:
D:\Program Files\Microsoft Configuration Manager\AdminConsole\XmlStorage\Extensions\Forms
D:\Program Files\Microsoft Configuration Manager\AdminConsole\bin
You can manually copy these files from the MDT source location, if necessary. Close all instances of the SCCM console and make sure there’s no locks on it. If still not there, try to remove and re-add the MDT Integration by re-running the wizard yet again.
