There are two ways to install Windows 8.
Windows 8 Installation FileEdit
You can get the Windows 8 Installer (Windows8-ConsumerPreview-setup.exe, 5MB) from http://go.microsoft.com/fwlink/?LinkId=242045
Note that using this installer will replace your current Windows 7 installation. The only advantage of uing this method of installation is the fact that the installer runs the Windows Upgrade Advisor Tool and Windows Easy Transfer Tool so that you can backup your files. The installer will then proceed to download only the files required for installation on your machine. Microsoft claims this method can reduce download by up to 25% compared to downloading the complete ISO image.
Windows 8 ISO ImageEdit
We recommend you to get the Windows 8 ISO Image from http://windows.microsoft.com/en-US/windows-8/iso Get the 64bit version of the ISO image. The only reason you will need it 32bit version is when you wish to test Windows 8 on hardware that does not support 64bit. Unless you are using an Intel Pentium 4 or AMD K7 (Athlon / Duron / Sempron) processor, or anything before 2005, your processor should be 64bit.
Once you have downloaded the ISO image (example: Windows8-ConsumerPreview-64bit-English.iso), you can either burn it to a DVD or mount the ISO image directly on a new virtual machine. Please read this article if you need instructions on how to burn the ISO image into a DVD.
Before installing Windows 8, please check that your hardware meets the minimum requirements, or your virtual machine has been allocated sufficient resources.
The requirements are:
|Hardware||Requirements||Processor||1 Gigahertz (GHz)|
|RAM||2 GB (1GB for 32bit)|
|Disk space||20 GB|
|Graphics Card||Microsoft DirectX9 device|
Note that for running Windows 8 in a Virtual Machine, we have successfully tested Windows 8 54bit with 1.5 GB of RAM.
