First of all, the admin template in your screenshot is the default Joomla 2.5 template called "Bluestork", and it's not made for Joomla 3. Joomla 3.x comes with a new default template called "Isis", so the first thing to do is to set "isis" as default admin template in Extensions > Template Manager:
That will probably solve the problem, but if it doesn't, here's a couple of other things to try:
- Clear your browsers cache
- Clear Joomla cache (System > Clear cache)
- Copy the folder
administrator/templates/isis and all of it's content from another Joomla 3.x installation (or from the full installation package available here) to the same location on your local site, and replace any existing files if prompted.
