Installing Windows from a USB flash drive has several advantages – First of all, the overall speed of the installation process will increase significantly, carrying a USB stick is much more convenient than a DVD, and finally it becomes possible to install the OS even on those systems that do not have a DVD drive, such as a netbook.
In this post, I will show you how to load the Windows installation on to your USB flash drive and make it bootable just like the DVD.
Tools Required:
1. USB flash drive with a minimum capacity of 4 GB.
2. Windows 7 set-up DVD.
DISKPART
This will start the Microsoft DiskPart utility as shown below:
LIST DISK
This will show you a list of available disks on your system. Disk 0 is usually the hard disk. In my case, Disk 5 is the USB drive (this can be a different one in your case). Now issue the command as shown below:
SELECT DISK 5
CLEAN CREATE PARTITION PRIMARY SELECT PARTITION 1 ACTIVE FORMAT FS=NTFS QUICK ASSIGN EXIT
H: CD BOOTCD BOOTBOOTSECT.EXE /NT60 M:(NOTE: M: is your USB drive letter)EXIT
