The whole process is presented below.

Requirements:
  • A USB memory stick (4GB minimum)
  • Windows installation DVD or ISO or files
  • A PC capable to boot from USB
Format the USB memory stick (or flash drive):
1 Plug in your USB memory stick (or flash drive).

2 Run Command Prompt as administrator.

Go to Start > All Programs > Accessories, then right click on Command Prompt and select “Run as administrator”

3 Type the following commands in Command Prompt (press Enter after each command):

DISKPART

LIST DISK

The command “LIST DISK” is used to display the number of your USB drive. This number is needed in the next step. For example, my memory stick is disk 1 (view image).

4 Format the USB drive by typing the following commands into the same window. Replace the number “1” with the number of your USB drive below.

SELECT DISK 1

You have now selected Disk 1.

Make the Drive Bootable:

In order to make the flash drive bootable, we’ll use the bootsect utility which is found in the Windows DVD or ISO.

5 Insert your Windows DVD into your drive. If you don’t have a DVD and you have an ISO, mount it using an application like Daemon Tools or Alcohol 52%.

6 Change directory to the DVD’s or ISO’s boot directory where bootsect lives by typing the following commands in command prompt (assume that the inserted DVD or the mounted ISO has been labeled disk F:\ by the computer):

F:

CD BOOT

7 Use bootsect to set the USB as a bootable NTFS drive prepared for a Windows image. Assuming that your USB flash drive has been labeled disk E:\ by the computer:

BOOTSECT /nt60 E:

8 You can now close the Command Prompt window.

bootsect

Copy the installation DVD or ISO files to the USB drive:

Copy everything from the Windows DVD or ISO to the USB memory stick or flash drive

Set your BIOS to boot from USB:

When the computer starts, enter the BIOS setup by pressing (F2 or F10 or Delete or ESC – it depends on the motherboard manufacturer). Then configure your computer’s boot device priority by setting the USB drive as the first boot device. Then save changes and exit. Your computer will start up by loading the content of the USB drive.
