creating system imaage

I have a windows 7 Pro installed on my pc with a 80 GB HDD. I want to upgrade HDD, but don't want to lose any data. If I create a system Imagine from with the back and restore will this make a copy of everything on this 80gb HDD so I reinstall it onto another HDD?

Thanks in advance.

Please post a screenshot of disk management. Is new disk larger than old disk? new disk can be cleared completely first?

When restoring a system image made by win7 built-in software:

• New disk will have exactly same partition layout. So restoring on smalller disk is impossible
• Because partitions are not in same layout yet.... win7 restore will clean the new disk and create the partition layout
• You need a win7 install dvd or win7 system repair disc and boot from it to start the restore
