IMPORTANT:

Back Up your Mac First:  

Be certain you Create a Time Machine Backup of your Mac, so that way you can have something to restore your Mac from, should anything go wrong with the reconfiguration.

After a normal restart, yes. While in it, the only thing it can be used as is an external drive.
