Install Windows 7/Vista From USB Drive [Detailed 100% Working Guide

 This guide works 100% for
Vista & Windows 7 unlike
most of the guides out
there. I have seen many
sites/blogs that have

“Install Vista from USB guide” but either with incomplete steps or not
working guide. I have also seen some guides that don’t’ use proper commands in this guide.
After spending many
hours I have come up with
this 100% working guide. I just did this method on
one of my friends machine
and installed the new
Windows 7 BETA. The main
advantage is that by using
USB drive you will be able to install Windows 7/Vista
in just 15 minutes. You can
also use this bootable USB
drive on friend ’s computer who doesn ’t have a DVD optical drive. 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. Requirements: *USB Flash Drive (Minimum
4GB) *Windows 7 or Vista
installation files. Follow the below steps to
create bootable Windows 7
/Vista USB drive using
which you can install
Windows 7/Vista easily.




1. Plug-in your USB flash
drive to USB port and move
all the contents from USB
drive to a safe location on
your system.


2. Open Command Prompt
with admin rights. Use any
of the below methods to
open Command Prompt
with admin rights. *Type cmd in Start menu
search box and hit Ctrl+
Shift+ Enter. Or *Go to Start menu > All
programs > Accessories,
right click on Command
Prompt and select Run as
administrator.


3. You need to know about
the USB drive a little bit.
Type in the following
commands in the command
prompt: First type DISKPART and hit
enter to see the below
message. Next type LIST DISK
command and note down
the Disk number (ex: Disk
1) of your USB flash drive. my Flash Drive Disk no is Disk 1.


4. Next type all the below
commands one by one.
Here I assume that your
disk drive no is “Disk 1 ”.If you have Disk 2 as your
USB flash drive then use
Disk 2.Refer the above step
to confirm it. So below are the
commands you need to
type and execute one by
one: SELECT DISK 1 CLEAN CREATE PARTITION
PRIMARY SELECT PARTITION 1 ACTIVE FORMAT FS=NTFS (Format process may take
few seconds) ASSIGN EXIT Don’t close the command prompt as we need to
execute one more
command at the next step.
Just minimize it.


5. Next insert your
Windows7/Vista DVD into
the optical drive and check
the drive letter of the DVD
drive. In this guide I will
assume that your DVD drive letter is “D” and USB drive letter is “H” (open my computer to know about
it).


6. Maximize the minimized
Command Prompt in the
4th step.Type the
following command now: D: CD BOOT and hit
enter.Where “D” is your DVD drive letter. CD BOOT and hit enter to
see the below message.


7. Type another command
given below to update the
USB drive with BOOTMGR
compatible code. BOOTSECT.EXE /NT60 H: Where “H” is your USB drive letter. Once you enter
the above command you
will see the below message.


8. Copy your Windows 7/
Vista DVD contents to the
USB flash drive.


9. Your USB drive is ready
to boot and install
Windows 7/Vista. Only
thing you need to change
the boot priority at the
BIOS to USB from the HDD or CD ROM drive. I won ’t explain it as it ’s just the matter the changing the
boot priority or enabling
the USB boot option in the
BIOS.


Note: If you are not able to
boot after following this guide means you haven ’t set the BIOS priority to USB.
If you got any problem in
following this guide feel
