While there are many resources today listing one or the other approach to install Windows 8 Developer Preview, there are barely few that tell you why or when you should adopt which approach. Not everyone's hardware is alike, therefore there is no “one size fits all” solution. Different folks need different solutions. And that's what this post aims to do. It lists out all the approaches for installation, describes when you should use which, and finally points you to useful links on the Web that show how to actually install the preview. So let's plunge right in.

Before you start, take a note of these things:

The Windows 8 Developer Preview is a pre-beta version of Windows 8 for developers. The prerelease software may change without notice.
You can't uninstall the Windows 8 Developer Preview. To go back to your previous operating system, you must reinstall it from restore or installation media.

Now that you are sure, you still want to go ahead, you can read on.

What to install

How to install

Now we come to the main part. There are several approaches for this.

Using VirtualBox (Oracle VM VirtualBox)

Use this option you don't want to go in for VMWARE. The general opinion among users seems to be that VMWARE is better on many counts than VirtualBox. But since I haven't tested them myself, I cant vouch for that fact.

Our very own C# Corer hero, Dhananjay Kumar aka debugmode, provides a step by step article on how to install Win 8 on a virtualbox:

Install on VMWARE

For this, you will need VMWARE Workstation 8 as that's the one supporting Windows 8 installations.
Use this option when you want to leverage the powerful features of virtualization. You can work on Win 8 without losing your existing data or OS. You just work in a virtualized environment.

Kunal Chowdhury demonstrates a step by step guide to do this:

For this approach, it's essential that your hardware (CPU) supports virtualization. You can verify that by checking your CPU (processor)'s configuration. For example, in my case, I determined that my processor does not support virtualization by going to the Intel site and checking the code of the processor against the listings. There are also many tools and utilities that can help determine this:

Microsoft Hardware-Assisted Virtualization Detection Tool

The Hardware-assisted virtualization (HAV) detection tool checks if the computer processor supports HAV and if this setting is enabled.

CPU-Z

CPU-Z is a freeware that gathers information on some of the main devices of your system.

Install on a Virtual Hard Disk (VHD)

Use this option when you can't use either of the two approaches mentioned above.

Scott Hanselman has written an excellent article on this approach.

Install by booting through a USB key

Patrick Hines describes his experience using this approach:
Installing Windows 8 Developer Preview on Samsung XE700T1A

You will need a USB key with minimum 16GB. And also loads of patience in case the process doesn't work and you need to troubleshoot it like Patrick did.
Dual boot with Win 7 and Win 8

This is a great option if you want to keep both Windows 8 and Windows 7 on the same machine, and you don't want to or can't use any of the above mentioned approaches.

Lifehacker.com describes a step by step guide to do this.

Direct install on a HDD.

This is the riskiest of the lot and will erase all the existing content on the HDD so do this only if you are willing to do a clean install. In my case, none of the above approaches worked, I wanted to install Win8 as soon as possible, and I had a spare HDD so I chose option 6 but I would strongly recommend not to use this approach as the developer preview software is not even in beta stage.
