Ghost 15 - How can I create images three partitions and recover them on the new greater disk?

I bought Norton Ghost 15.0.
I have my computer with three partitions:
1. c:\ - MS-Windows 7 (system)
2. d:\ - NTFS for MS-Windows 7 (data)
3. ext3 - Linux distribution Ubuntu
I want to create three images (these three partitions) on the external disk (USB).

This split is recommended in the instructions "Norton Ghost 15.0 User's Guide".

Then I want to change my disk and recover all three partitions. New disk is greater.
A) Is it possible?
B) Could you explain me this process step by step?
