Win8 mobile hard disk installation disk is the easiest to make tutorial

There are many tools for making Win8 mobile hard disk installation disk, such as Windows 8 USB Installer Maker, Windows 7 USB/DVD Download Tool, etc., but today share the simplest and not I need to use these methods of making tools (I also share the others from the network, just as a summary, not my original method):
Preparation:
1.Windows8 ISO image
2. WinRAR compression tool
Method:
1. Create a disk partition on the mobile hard disk (you will make a partition of Win8 installation disk)
2. Extract the ISO image of Windows8 to the partition
3. Right click “My Computer” & ——“Manage”——“Disk Management", find the partition of your newly created mobile hard disk, then right click and select “Mark partition as active partition” ;
All steps are completed.
Restart the computer and select USB boot. Then I entered the system installation interface, and there is nothing to say about the remaining steps.
Note: I tried Windows 8 USB Installer Maker before, after all the steps are completed, I still can't start the installation. Later, the partition is set to active, and it is solved.
This method is probably the easiest and easiest way to make a mobile hard disk boot disk. Sometimes the simplest is often the best.
