Any operating System such as Window xp/7/8, linux, unix, Mac OS can be installed on hard disk very easily but if we talk about USB drive or Pen Drive then there is some difference in its File Structure, Formatting etc because of this difference between hard disk and pen drives we can’t follow the same procedure as we often follow to install windows 7 on hard disk. So we need some tools to make pendive like hard disk.

Tools are listed below

  1. Daemon Tools
  2. NT6 x Fast Installer
  3. GetWaikTools
  4. Install RMPrepUSB Full 2.1.720

Daemon Tools

By using these tools we are going to make pendrive that behave like hard disk, A little size portable hard disk inside pendrive its sounds nice.

Here we need 16 gb USB 3.0 pendrive, windows cd/dvd or ISO file of windows and above mention tools. I am using windows 7 ISO file.

Daemon tools is a software that is often used to create ISO file from cd/dvd or vice versa. Here we will need either iso file of window 7 or 8 what ever version you want to use doesn’t matter or cd/dvd of windows. If you have cd/dvd of windows then you don’t need to use Daemon Tools, just insert windows cd/dvd into computer.
