The pursuit of new technology friends must be very interested in Windows 8, I believe you have also downloaded the just released Win8 development preview version. However, many people will encounter a problem when installing directly in the Windows environment, WIN8 Development Preview version will be directly on the current system upgrade installation.
Although you can still enter the WIN8 and the old system after installation, however, because the files are mixed in one partition is very inconvenient, plus WIN8 only the preview version of a number of destabilizing factors, in the event of a problem is likely to affect your current system use, so the best way is to install WIN8 to separate partitions.
If you have a burner and a blank DVD, burn the downloaded Win8 image file directly into a CD-ROM, and then install it in a new way by starting the disc. But what about not having a device to burn? I began to struggle with this problem, fortunately finally found a solution, in fact, the principle of the same as the original Win7.
First of all, the Win8 mirror with WinRAR software decompression, not directly run the root directory of the setup file, but into the subdirectory source folder, in this folder also has a setup file, we only need to run this file can be installed into a new section of the Win8. If your computer has a virtual optical drive tool, then mount the image directly, from the source folder running Setup is the same, you can save the time to decompress.
After you start the installation, you first need to choose whether to search for the currently available update files, and then the choice of installation method, remember the custom we want to choose the way (second), and then we will see the familiar Partition selection screen, OK to start installation. If after a period of time, you do not want to Win8, directly format the Win8 of the partition can.
