Install windows 7 from usb drive

Folks,

This is a very old procedure which i did in 2007/8/9. But i dont hold any blog at that time 😉 hence iam updating today with latest process including with images..its very easy for beginners as i will explain from scratch…

Requirements

1. Copy of win7 files(DVD/ISO file)

2. Min 4GB pendrive

Lets start the process..

Insert your DVD in your drive and make a note of your CD/DVD drive name and along with your pendrive drive name.

Lets say my DVD drive is D and my USBdrive/pendrive is E

Open the command prompt with admin rights.

cmd-prompt-usb-boot

DISKPART

this loads the diskpart application we need to proceed

Then type

LIST DISK

the image above shows our 32 GB USB drive is listed as DISK 2

so you have to type

SELECT DISK 2 (your USB Drive may have a different number, don’t follow exactly this text it depends on your usb drive)

You will get a successful response “Disk 2 is now the selected disk”

clean-cmd-usb

Next we want to clean the USB drive

Type:

CLEAN

you will get a successful response ‘DiskPart succeeded in cleaning the disk”.

usb-drive-cleanprocess

After the drive is cleaned follow the list in the image above (detailed below in list order) – you can also note the successful text responses from the OS as you enter each command.

SELECT DISK 2 (or what number your USB drive has)

CREATE PARTITION PRIMARY

SELECT PARTITION 1

ACTIVE

FORMAT FS=NTFS

Formatting can take a little time depending on the size of the drive, our 32GB unit took about 10 minutes to format – you will see a percentage readout until it is finished.

Next type:

ASSIGN

EXIT (DISK PART will exit)

Type D: CD BOOT (substitute the “D” if necessary with the letter of your Windows 7 DVD drive)

then key

CD BOOT

then

BOOTSECT.EXE /NT60 E: (substitute the “E” if necessary with the letter of your now ready USB drive) – we are telling the system to create a boot sector file on the USB drive.

Now you can exit the command prompt and copy all the files on the Windows 7 DVD to the USB drive.

Once this step is finished you’ll be ready to boot from this drive, all you need to do is configure your motherboard bios setup to boot first from USB rather than hard drive or optical drive. If you don’t know how to do this, refer to your specific motherboard manual or search the internet.
