Dual booting is a great way to have two operating systems installed on your computer at the same time. It allows you to have two different sets of programs and files, so you can switch between them easily. There are a few different ways to dual boot Windows 7 and Mac. The easiest way is to use a USB drive. Just plug the drive into your computer and Windows will automatically install the OS on it. You can also use a partitioning program like Partition Master to create separate partitions for each OS. If you don’t want to use a USB drive or partitioning program, you can also dual boot using a CD or DVD. Just insert the disc into your computer and Windows will start up automatically. You’ll then need to choose which OS to install. ..
