Dual Booting Windows

If you've decided to make the move to windows 7 but aren't convinced you'll be sticking with it, or are concerned about other issues, a dual boot option is probably wisest.To dual-boot a pc you'll need to partition your hard drive using a program such as partition Magic (http://partitionmagic.com) .You need to create NTFS partition and will require at least 20 GB of available hard disk space if you wish to run two operating systems alongside each other.Remember that you'll also need to retain a comparable amount of space for your existing XP or Vista system.Once you've got a suitably partioned drive, boot back into windows and you should find a new drive in My Computer.Double click you can open it.To install windows 7,insert the disc as soon as the PC starts up or insert while your existing version of windows is running.When the screen appears asking where you want to install windows, ensure you choose the partition matching the drive letter you've just created.Because that partition is empty , windows 7 will perform a clean installation.
