By:- www.rksharma.co.cc

Requirements:

·        USB Flash Drive (Minimum 4GB)

·        Windows 7 or Vista installation files.

Below steps will create bootable Windows 7/Vista USB drive using which Windows 7/Vista can install easily.


1) Plug-in your USB flash drive to USB port


2) Open Command Prompt with admin rights.

Methods to open Command Prompt with admin rights:-

Type cmd in Start menu search box and hit Ctrl+ Shift+ Enter.

Or

Start menu à All programs à Accessories, right click on Command Prompt and select Run as administrator.

3) First type DISKPART and hit enter.
Next type LIST DISK command and hit enter and note down the Disk number (like: Disk 1) of your USB flash drive.


 4) I am assuming your disk drive no is “Disk 1”. If you have Disk 2 as your USB flash drive then use Disk 2. Use the above step to confirm it.
Now type the below commands one by one:
SELECT DISK 1
CLEAN
CREATE PARTITION PRIMARY
SELECT PARTITION 1
ACTIVE
FORMAT FS=NTFS
(Format process may take some time)
ASSIGN
EXIT
Don’t close the command prompt. We need to execute one more command. (Just minimized it).


5) Insert Windows7/Vista DVD into the DVD Drive and check the drive letter of the DVD drive. Here I will assume that your DVD drive letter is “G” and USB drive letter is “H”.


6) Maximize the minimized Command Prompt in the 4th step. Type the command now:
G: CD BOOT and hit enter. (Where “G” is your DVD drive letter)
Now type CD BOOT command and hit enter.


7) Type BOOTSECT.EXE /NT60 H: command and hit Enter to update the USB drive with BOOTMGR compatible code. (Where “H” is your USB drive letter)


8) Now copy Windows 7/Vista DVD contents to the USB flash drive.


9) Now USB drive is ready to boot and install Windows 7/Vista. Just change the boot priority at the BIOS to USB.
