Happy Windows 8 Consumer Preview day! Or, rather, happy day-after-Windows-8…. you get the idea. As an astute Maximum PC reader, you’re no doubt itching to get your hands on a not-quite-final build of Windows 8 to tinker around with.
But here’s the problem: You like using your current operating system. In fact, you probably have a great number of files, applications, and games all intertwined with your current operating system. And the absolute last thing you want to do – aside from learning how to use the Metro UI (we kid, we kid) – is back up everything within your operating system, wipe your drive, and introduce a fresh-faced Windows 8 into your life as your primary OS. Just think of all the application reinstallations you’ll have to go through! (Ninite is your friend, but we digress)
Luckily, you have two awesome options when it comes to testing out Windows 8 without mucking up your primary Windows installation, settings, files, or any of that. You can split your current hard drive storage setup to create an extra, blank partition – Windows 8 goes there. Or, if you just want to monkey around in a self-contained environment within your current operating system, you can install Windows 8 onto a virtual PC.
Which do you pick? It’s entirely up to you. A dedicated installation on a new partition gives Windows 8 the full attention of your system’s mighty resources. The downside? You’ll have to suffer through the boot menu every time you load your PC; You won’t be able to access your true “primary” operating system from Windows 8; Any changes (or issues) you create are permanent, as you don’t really get a chance to “roll back” that which you’ve done.
Virtualization, on the other hand, costs you system resources and overall speed – it can be a real hog – but it allows you to marry Windows 8 to your existing operating system. Transferring files is easy; Jumping between the two operating systems is easier; You can test out apps in Windows 8 and still be able to use them in your existing OS if things go sour; And, most importantly, you can quickly revert back to prior versions of the OS and easily delete your virtual Windows 8 once you’re done toying around.
That’s a super-quick overview of some of the pros and cons of dual-booting versus virtualization. Here’s how you do both:
Dual-Booting
Grab the Windows 8 Consumer Preview setup file and give ‘er a run. While your version of the operating system downloads (32-bit or 64-bit, depending on what the setup program picks for your PC), go check your available hard drive space in Windows explorer. You’ll need to have at least 16 free gigabytes for a 32-bit installation of Windows 8 or 20 free gigabytes for a 64-bit installation.
Once finished, Windows will prompt you to install Windows 8 by giving you three options to pick from: “Install Now,” “Install on another partition,” and “Install later.” Pick option number two (partition), and the subsequent screen will ask you how you want to go about creating the installation media you’ll need to use.


While we always recommend that you let Windows 8 create an installation vehicle out of a USB key when possible (it’s just so speedy), your success in getting this approach to actually install Windows 8 entirely depends on just how well your motherboard supports USB-based installations. In other words, it might not work for you: We’ve previously run into problems when plugging our flash drives into USB 3.0 slots to perform the installation, so avoid that if you find yourself hitting your head against the wall when trying to install Windows 8 using a USB drive.
The Windows Consumer Preview setup program will automatically format your key and slap the necessary files on it. As this process chugs along, fire up your control panel (Windows 7 users) and click on the Administrative Tools icon. From there, double-click on “Computer Management,” and then select the “Disk Management” option on the left-hand sidebar. Roll up your shirtsleeves: It’s time to partition your hard drive.


Everyone’s hard drive setup can vary, so we’ll just walk you through the basics of splitting a single drive partition into two. Right-click on the graphical storage “chunk” that’s home to your primary NTFS volume (C:) and select “Shrink Volume.” Input just how much you want to shave off your primary operating system’s partition – remember, 1,024 megabytes equals one gigabyte -- and hit the “Shrink” button.

What do you get? A new chunk of black, unallocated space to the right of your once-larger primary partition. Right-click on this empty space and select “New Simple Volume.” The prompts are fairly self-explanatory after this point – just make sure to give your new partition a recognizable name and format it as an NTFS partition. Voila. You’re ready to install Windows 8.




Once the Windows Consumer Preview setup program has finished with your USB key, restart your computer. As it reboots, watch your boot sequence for any prompts related to “booting” or “boot order” – in our case, we only have to hit the F12 key to access a “select where you want to boot from” menu. But since your motherboard is surely different, this option might be mapped to another key. Or, worse, you might have to go into your BIOS settings and change the order of how your system boots off of its various devices. Again, this setting is found in different places on different motherboards, so you’re on your own for this small – but critical – step.

Select the correct option – USB HDD, in our case – reboot your computer, and the official Windows 8 installation program should automatically fire up. Click on the “Install Now” button, enter you product key (that you received way back when creating your USB Windows 8 installer), accept Microsoft’s license terms, and select the option for a “Custom” installation. Pick the partition you previously created (hence the importance of giving it a good and noteworthy name), click on “Next,” and go make yourself a pleasant beverage while you wait for the installer to work its magic.

From there, it’s all downhill: Windows 8 will reboot your system a few times before the installation finishes, and it’ll then ask you a series of questions to help you personalize your operating system prior to the first official run – including asking you to log into your official Microsoft account, if you so choose. One last tip, however: When you go to reboot your system to actually load Windows 8 for the first time, take out your USB key during your motherboard’s boot sequence. If not, and if you set your system to always boot off any available USB devices before your hard drive, you’ll find yourself continually looping back to the Windows 8 installation program. That’s just silly.
