install windows 7 from usb drive

Step 1 – Let’s create a bootable USD Drive!
•Clearly, the first thing you need is a USB drive and the one I used was an 8GB Seagate model.
•Plug the drive into your PC.
•Open a command prompt as administrator.
•Get the drive number by typing:
•diskpart
•list disk
•On my machine the USB disk was number 1.
•Format the drive by typing:
•select disk 1
•clean
•create partition primary
•select partition 1
•active
•format fs=NTFS
•assign
•exit
•Mount the Windows 7 beta iso using Daemon Tools or similar.
•Navigate to the boot directory
•cd E:\boot
•Using bootsect, we’ll make the USB drive a bootable NTFS drive, ready for a Windows 7 image (my drive was labeled G):
•bootsect /nt60 G:
•We are finished with the command prompt now, so you can close it.
Step 2 – Copy the installation files from the mounted Windows 7 iso to the USB drive.

Step 3 – Install on the computer
•Plug in the USB drive and turn on computer
•On start up press to select the bootable drive
•Select the USB drive and press return
•The computer will boot from the USB drive and the installation will begin
•Install as normal.
