Installing Windows 8

Windows 8 Installation Experience

I am upgrading my laptop from Windows 8 Release Preview to Windows 8 Pro. I will post the experience here.
I download .iso file from MSDN and burn on a DVD.
Installing from the disk
You MUST need a key to install Windows 8. You can find your key in your MSDN account. 
Windows will ask if you want to keep your personal files or remove everything.
Message- Installing Windows 8 .. 67% completed already in about 10 mins. 
Followed default instructions.
Windows 8 will ask you for an email (Microsoft account, Hotmail or another email you used with Microsoft) and password. That will be your userid.
Everything is installed.
Start using Windows 8.
Will continue posting my experience.
