Create Boot-able USB drive for windows 7 or windows 8 without any software

Hello  friends...

Installing Windows from a USB flash drive has several advantages – First of all, the overall speed of the installation process will increase significantly, carrying a USB stick is much more convenient than a DVD, and finally it becomes possible to install the OS even on those systems that do not have a DVD drive, such as a netbook.

You can create a boot-able USB using software provided by Microsoft. But one of my friend told me that he was not able to make his USB boot-able using this software. So, here is the post to make any USB boot-able without any software, using command prompt.

Tools Required:

1. USB drive with more than 4 GB capacity.
2. Windows 7 or Windows 8 DVD.

Step 1: Format the USB drive:

• Plug in USB drive.
• Run command Prompt as Administrator. (Go to start -> All Programs -> Accessories -> right click on "Command Prompt" and select run as administrator.)
• In CMD type
  diskpart
  list disk
• This will show you a list of  available disks on your system. Disk 0 is usually the hard disk. In my case, Disk 1 is the USB drive (this can be a different one in your case). Now issue the command as shown below:
  select disk 1

• Now type and execute these step by step.
  clean
  create partition primary
  select partition 1
  active
  format fs=NTFS
  assign
  exit

This is just to make your disk formatted and ready with partitions.

Step 2: Make the drive boot-able:

• Now insert your windows7 or windows 8 DVD in your Drive.
• In my case it is in drive G:
• Now type and execute
  G:
  cd boot
• In my case the USB disk is labeled as h:
• Now type and execute
  bootsect /nt60 h:

• You can close now Command Prompt window.

Step 4: Copy the installation DVD to USB:

•  Now simply copy the contents of your Windows DVD into USB drive.

That's it !!! Your USB is now ready to boot and install the OS. Just enable the "USB Boot" option and change the "Boot priority to USB device from Hard Disk" in BIOS option.

Enjoy... Have Fun...!!!
