How to: Install Windows 7 on Parallels
Windows 7 is perhaps Microsofts greatest achievement. With the release of 8 and 8.1, they proved they were no longer able to produce a properly working operating system. Let me show you how to install the popular Operating System onto your Mac using Parallels Desktop 9. This might work with Desktop 10 being that 10 and 9 are absolutely the same with some minor UI differences either way both 9 and 10 will have links to amazon where you can purchase either of the two. I've also cared to include a link to where you can purchase a physical CD if you're still old school like me, I still have the Professional 64 bit disk for XP.

Downloading the ISO file is 100% legal as it is in no way pirating software, you still need the product key to have the OS function beyond the trial period. I did have the product key with me and installed the OS with no problem. If you want to instal using a CD you choose the CD option and wait for parallels to read your CD from the drive.
