The biggest question you need to answer is how much space you want Windows to have left over. ( How to put Clonezilla on a CD or USB drive.) However you do it, just make sure you have a really good backup, before you begin.
A free utility such as Clonezilla Live can be useful for that.

If the Ubuntu installation goes wrong, it can wipe both hard drives. Step 1: Do a complete backup of both your SDD and HDD to external media.
