Most notebooks and Net books don’t have CD/DVD drive to make them more and more compact. So to install windows you need to use a USB Pendrive.
1. Must have a Windows 8 ISO file. You can download it or you can create it with a Windows 8 DVD.
2. A USB Stick of 4GB or larger (All data will be lost on the drive).
Now follow these steps:
Plug the USB Pen-drive in your computer. Open The command prompt and type the following commands:
diskpart list disk select disk 1 ( disk one being the USB drive ) clean create partition primary select partition 1 active format fs=ntfs ( you can also format in fat32 or fat or add quick for a quick format ) assign exit
Now extract the windows 8 ISO file on the pen drive/USB stick and you are done.
