Install Windows 7 From a USB
Flash Drive or USB Hard Drive
The
main advantage is that by using USB
drive you will be able to install
Windows 7 or Windows 8 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 Windows 8
installation files.
Procedure:
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
Next type LIST DISK command and
note down the Disk number (ex:
Disk 1) of your USB flash drive.
4. Next type all the below commands
one by one. Here I assume that your
disk drive no is “Disk 1 ”
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/
Windows 8 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”
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 :
8. Copy your Windows 7 or Windows
8 DVD contents to the USB flash
drive.
9. Your USB drive is ready to boot
and install Windows 7 or Windows 8.
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.
