The Simple Help weblog runs through installing Windows 7 on your Mac using Parallels, so you can experience the hype—from the safety of an easily deletable virtual machine. The installation process is nothing new to most Lifehacker readers, requiring only a copy of the Windows 7 beta, a recent version of Parallels Desktop, and some free time. But this guide has a full walkthrough of all the steps for the less tech-savvy, useful for sharing with friends that aren't as technically inclined. If you want to use the new Aero-enabled features, you will need to install Windows 7 as a dual-boot OS using Boot Camp instead—Aero doesn't work inside a virtual machine. If you just want to run Windows 7 alongside your current XP or Vista installations, our guide to dual-booting Windows 7 with XP or Vista is for you. Alternately, you can also multi-boot your Windows 7 desktop with Linux.
