For those who can’t wait to try out the latest Consumer Preview of Windows 8, but are afraid of loosing their existing Windows 7 or Windows XP installation – here is a quick guide which will walk you through installing and dual bootin Windows 8 with your existing windows installation. In this tutorial I will be installing Windows 8 Consumer Preview while keeping my existing Windows 7.
Minimum of 1 GHz processor
Atleast 1GB of RAM (or 2GB for 64-bit)
Atleast 16GB of storage (or 20GB for 64-bit)
A DirectX 9 graphics card with WDDM 1.0 support
Step 1: Pre-requisites
Create a 20Gb NTFS partition (atleast, because Windows 8 needs 16 Gb to run) on your HDD and keep it aside for windows 8. I personally created a 60Gb partition so that I could play around with installing application etc.
