How do I create a Win7 Boot Disc for a full system re-boot?

I custom built my PC, a few years ago. The motherboard came with Win7 Home Premium installed. It did NOT come with a boot disc. I have tried to do a simple system recovery from back-up image and it failed. I feel the only answer is a full system recovery but, I need my Win7 activation code and a boot disc to accomplish the task. I don't know how or where to find the code or how to create the boot disc. Yes, I am a PC novice and I need help. PLEASE!

I've never seen a motherboard come with an Operating System but in the scheme of bundling I guess it's possible. Whoever installed the OS should have, and is required to by the licensing, given you the COA/Certificate of Authenticity that has the Product Key on it. If you don't have that you can retrieve it from the Registry of a RUNNING Windows computer using Belarc's Advisor or Magical Jellybean's Keyfinder, both free.

To use system recovery options, you'll need a Windows installation disc or access to the recovery options provided by your computer manufacturer. If you don't have either of those choices, you can create a system repair disc to access system recovery options.
