Windows 8 is the codename for the upcoming version of Microsoft Windows that follows Windows 7. It features a new Metro-style interface that is designed for touchscreen, mouse, keyboard, and pen input. It also adds support for the ARM processor architecture in addition to the previously supported x86 microprocessors from Intel and AMD. Its server counterpart is codenamed Windows Server 8.
If you like to try Windows 8 but don’t want to give up Windows 7. Here’s how to dual boot Windows 8 with your current Windows 7 installation so you can run them both side by side. All you need to do is create a new partition for Windows 8, install it on that partition, and then edit your new boot menu so Windows 7 stays the default OS.
