How to install Win8 system on a separate partition

Nowadays Windows 8 system has become more and more popular, and some users who do not understand the computer also want to experience Windows 8 system. But if they directly download an image to install in the Windows environment, then the image will be upgraded and installed on the current system. How to install Win8 on a separate partition?
Although you can still enter Win8 and the old system separately after installation, but it is very inconvenient because the files are mixed on one partition, plus Win8 is only a preview version. Stabilization factors, if the problem is likely to affect your current system usage, the best way is to install Win8 on a separate partition.
If you have a burner and a blank DVD, burn the downloaded Win8 image file directly to a disc, and then install it by CD-ROM. However, what should I do if I don't have a burning device? I was entangled in this problem at first, but fortunately I finally found a solution. In fact, the principle is the same as that of Win7.
First of all, the Win8 image is decompressed with WinRAR and other software. Do not run the setup file of the root directory directly, but enter the subdirectory source folder. There is also a setup file in this folder. We only need to run this file. You can install Win8 into a new partition. If you have a virtual drive in your computer, mount the image directly, and run setup from the source folder. You can also save the decompression time.
After starting the installation, you first need to choose whether to search for the currently available update file, then the installation method, remember the Custom mode we want to select (the second item), and then you will see the familiar partition selection screen. Ok, let's get started. If after a while, you don't want Win8, just format the partition where Win8 is located.
