How To Create Windows 8 USB Installer

Below are the easy steps to create a Windows 8 bootable USB Installer. You need at least 4 GB USB Flash Drive and Windows 8 Installer. If your Windows 8 installer is an .iso file downloaded from MSDN or somewhere, you may mount it using a virtual CD/DVD manager. I use Portable WinCDEmu to mount mine. 

1. Plugin the USB Drive and make sure you have backup its contents coz it will be wiped out.
2. Run Command Prompt with admin rights. From the Start menu search box, type cmd and press Ctrl+ Shift+ Enter.
3. Type DISKPART in the command prompt.
4. Type LIST DISK to list your disk number and take note of that number. In my case its Disk 2.
 

Issue the ff. commands at the DISKPART prompt one by one.
     SELECT DISK 2 (replace DISK 2 with your disk #)
     CLEAN
     CREATE PARTITION PRIMARY
     SELECT PARTITION 1
     ACTIVE
     FORMAT FS=NTFS (this part may take some time)
     ASSIGN
     EXIT

5. Minimize the command prompt and load/mount your Windows 8 Installer
6. Restore/Maximize the command prompt.
7. Type D: and press enter (change D: with the drive letter of your Windows 8 Installer.)
8. Type CD Boot and press enter.
9. Type BOOTSECT.EXE /NT60 F: and press enter. (change the F with your usb flash drive letter.)
10. Copy all the content of your Windows 8 Installer to the usb flash drive.

That's it! Now you can boot and install Windows 8 from your newly created usb flash installer.
