Windows 7 or Windows Vista

[Mutilda]

Hello
I will soon buy a computer (in spare parts). I wonder whether it is really necessary that I buy Vista. I think of downloading Windows 7 and of installing it on new the config. Think that with beta, my computer will be able to turn on until October (left 7). My use will be of 60% Internet and 40% gaming.

Thank you

If you're dying to try out Windows 7 but aren't ready to give up your installation of XP or Vista, let's take a look at how to dual boot Windows 7 with XP or Vista.

Download the Windows 7 Beta and Burn It to a DVD
Assuming you've already downloaded a fresh copy of Windows 7, you'll need to burn it to a DVD in order to do a fresh installation. To handle this task, grab a copy of the most popular CD and DVD burning tool ImgBurn, burn the ISO to a DVD, and move right along to step 1.

Partition Your Hard Drive
Before you go installing Windows 7, the first thing you need to do is create a new partition on your hard drive to hold the new installation of Windows. Partitioning your hard drive will vary depending on whether you're running XP or Vista—namely because Vista has a partition tool baked in, XP does not.
