Hi,
I wouldnt personally recommend installing windows 2008 R2 on a laptop even though you have quad core processor.
You have to install it on a server ( dell / hP). And in real world scenario , none of the org recommend you to install on a laptop and waste a license as the license is costly.
You need to have 64bit firmware
