How To: Install Windows 7 Or Windows 8 From USB Drive

 

This guide works 100% for Windows 7 and Windows 8 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. After spending many hours I have come up with this 100% working guide to install Windows 7 or Windows 8 from USB flash drive.

Bootable USB drive

I just did this method on one of my friends machine and installed Windows 7. 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. And if your PC doesn’t support booting from USB, you can still install Windows from USB by following our how to install Windows 7/8 from USB drive even if your PC doesn’t support USB boot feature.

Preparing Windows 7 bootable USB

Requirements:

  • USB Flash Drive (Minimum 4GB)
  • Windows 7 or Windows 8 installation files.

Follow the below steps to create bootable Windows 7/Windows 8 USB drive using which you can install Windows 7 or Windows 8 easily.

Procedure:

Step 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.

Step 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 CtrlShiftEnter.

Or

*Go to Start menu > All programs > Accessories, right click on Command Prompt and select Run as administrator.

Step 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.

Step 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 Quick

(In the above command, replace NTFS with FAT32 if your system supports UEFI)

(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.

Step 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” (open my computer to know about it).

Step 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.

Step 7: Type another command given below to update the USB drive with BOOTMGR compatible code.

BOOTSECT.EXE /NT60 H:

14

Where “H” is your USB drive letter. Once you enter the above command you will see the below message.

Step 8: Copy your Windows 7 or Windows 8 DVD contents to the USB flash drive.

Step 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.

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 free to ask questions by leaving comment.

Update on Jan 11, 2012: If you find this guide difficult to follow, please use the easy-to-use guide to create a bootable USB to install Windows 7  or Windows 8 using official tool.

This guide works 100% for Windows 8/8.1 as well. Make sure you follow all steps correctly and launch the Command Prompt with admin rights (as given in the guide) to avoid errors. Good luck!
