How To Install Windows 7 Vista From USB Drive 100% working

This Tutorial will show you how to make your USB BOOTABLE for Windows 7/ Vista.

Having a bootable USB is very essential, especially if you are a Notbook user. Using bootable USB to install an operating system (OS) not only makes the 


installation faster, but also saves a DVD.


The main and biggest advantage that Installing windows 7/ Vista From USB is very fast it takes almost 20 to 30 minutes Only.


Note that this bootable USB guide will not work if you are trying to make a bootable USB on XP computer.


For this you require: 


1)Atleast 4Gb USB DRIVE


2) Windows 7/ Vista installation files.


The method is very simple and you can use without any hassles. Needless to say that your motherboard should support USB Boot feature to make use of the bootable USB drive.


Just follow these steps. 


NOTE: write commands correctly with spaces where require.


1) Open Command Prompt as administrator rights.


To access Command Prompt as administrator, Write "cmd" in start menu search box and hit CTRL+SHIFT+ENTER.


2) In Command Prompt write "DISKPART".

3) Now type "List DISK".

4) Now select the disk which is your USB. It may be (Disk 1, disk 2, or Disk 3) so choose carefully. Here mine its Disk 3.
   Format should be right this( select disk 3).

5) Now write "CLEAN" and hit "ENTER".

6) Type"CREATE PARTITION PRIMARY".

7) Type "SELECT PARTITION 1".

8) Type "ACTIVE".

9) Type "FORMAT FS=NTFS". ( Formating will take some time 10 to 15 minutes).

10) Type "ASSIGN".

11) Type "EXIT".

This is how the whole procedure looks.

Dont close Command Prompt as we need it.


Now insert Windows 7/Vista Dvd in the DVD-ROM.


12) Type "D: CD BOOT". (Name the drive which contain windows 7/Vista.)

13) Type "CD BOOT" again.

14) Type "BOOTSECT.EXE /NT60 G:" (Here I wrote G: because after formating in step 9 the drive name wil change automatically so check it before commanding). G: is USB DRIVE.


Given above command is to update the USB drive with BOOTMGR compatible code.

This will show full procedure.

Done. Close Command Prompt and copy Windows 7/Vista DVD contents into USB Drive.


Note: Before using USB as your boot device, Change boot priority from BIOS to USB. If you dont change Boot Priority USB will not Boot.
