There are a number of tools available to make WIN8 mobile hard disk installation disks, such as Windows 8 USB Installer maker,windows 7 Usb/dvd Download tool, and so on, but today we share one of the simplest methods that do not require the use of these tools ( I also see from the network of others to share, only as a summary, not my original method:
Preparatory work:
ISO image of 1.WINDOWS8
2.WinRAR Compression Tool
Method:
1. Create a disk partition on the mobile hard drive (you will be making a partition of the WIN8 installation disk)
2. Extract the Windows8 ISO image to the partition
3. Right--"My Computer"-"management"-"Disk Management", find the partition of your newly-created mobile hard disk, and then right-click to select "Mark partition as active partition"
This completes all steps.
Reboot the computer and choose USB boot. The next step into the system installation interface, the rest of the steps there is nothing to say.
Note: After trying to use Windows 8 USB Installer Maker, after all the steps have been completed, you will not be able to start the installation, then you can set the partition as active and then resolve it.
This method is probably the easiest and easiest way to make a mobile hard disk boot disk, and sometimes the simplest one is always the best.
