Install Windows 7 Via USB Drive (Flash or external HDD)

Intalling Windows 7 Via a USB drive is so Fast! About 15 minutes fast. Why use a DVD any more. Even the EEE PC’s don’t have CD Roms so you need to use a USB Drive Any way.

There are several how-to’s out there that are not accurate but this how-to is 100% working.

 

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. In the below screenshot 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).

If you don’t have the CD then copy to ISO contents to the HDD and use C Drive

 

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. Again if you using a ISO on your desktop instead of a DVD Rom then use C Drive and find BootSect.exe on in the DVD Contents, look in Boot.

 

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.
