Running Multiple Operating Systems
Nowadays, you don’t need separate computers to run different operating systems. Sure, Microsoft’s Windows is by far the most common OS running on the millions of PCs in daily use, but that doesn’t mean using just XP or Vista.
You can add a newer, even older, Windows version to your existing one, and you can even choose which one to start with from a boot menu when you turn the PC on. Even the latest Macs also offer the ability to dual-boot Mac OS X and Windows via the company’s Boot Camp utility. And both Macs and PCs can run popular versions of the GNU/Linux operating system, such as Ubuntu and openSuSE.
(Warning: Creating multiboot configurations often involves using disk-partitioning techniques that can damage or destroy your data. Before adding, removing, or resizing partitions, modifying boot loader software, or altering the master boot record, be sure to back up your files.)
