Changing hard drives with Clonezilla

For whatever it's worth, System Restore on Vista didn't know the "new" c: drive that I upgraded to, and system restore failed.

Right-click My Computer, Properties.
System Protection (left side)
Uncheck anything said as (Missing) and make certain C: that is (Local) is checked, apply, (yes) ok.

Now System Restore functions properly. Also, you can use this to put System Restore on an optional other disk.
