Create an OS instalation from an USB pen drive

This tutorial was tested with Microsoft Windows 7 Home Premium.

I’ve created a bootable installation of Windows 7 from an USB pen drive.

The steps you should follow to do that:


Step 1:

Windows Key + “R” key;



Step 2:


  • On the prompt of Disk Part type “list disk” to see the disks of your computer.
    • My USB pen drive is the disk 2.
  • Type: select disk “number of your usb disk” (CAUTION: Make sure that you know which is your USB disk drive).
  • “clean”
  • “create partition primary”
  • “format fs=fat32 quick”
  • “active”
  • “exit”

Step 3:

After configure this you can copy all the files of your Windows DVD (or other Operating System supported by this file system – fat32) to this USB drive. It is able to boot from this drive 😉
