How to install Windows 7 alongside Windows 8?

Question

I bought a new laptop (HP 4540s) and also a Windows 8 DVD. I installed Windows 8 but it's not user friendly. Now I want to install Windows 7 on the same laptop while keeping Windows 8 also (multiboot) because this is a company laptop and it does not want me to remove Windows 8.

How I can install Windows 7 alongside Windows 8 please?

I have Windows 7 Pro original DVD including product key.
Note : This laptop is DOS base.

Solution

Instead of dual booting, you can install Hyper-V on Windows 8, and then use Windows 7 as a virtual machine within Windows 8. This would let you use both operating systems at the same time.
