Booting Operating systems from pendrive - An easy guide

There is a common problem that we all face with our laptops is that the optical drives stop working . Almost all brands of laptops have a maximum span of 1.5 to 2 years for the optical drives ( evenless in many cases) .
So there is always a problem when you want to install a new operating system from a bootable disk .
I have been trying to install the BACKTRACK 5 operating system on my system but I too faced the same problem that my optical drive is not working and currently i m not in budget to replace it .
So i went on to try and boot up through the usb pen drive .

I am posting two different methods . First is for girls and lame users which is a ready made software that creates your pendrive bootable and copies all the files from the image onto the drive. All you have to do is to change the boot order of your BIOS to boot from the USB.

Second method is for the guys who want to know the indepth working of the entire process . We will create a bootable pendrive from command prompt .

First Method

Here is the software that will solve your purpose of making pen drive or flash drives bootable . 
Simply download it and follow the on screen instructions .
You should have an image file of the operating system you want to boot  and upon restarting your computer you will have to change the boot order to USB drive .


Second Method

Now in this method we will create a bootable disk from command prompt . There are a series of commands that you have to follow to make ur pen drive bootable .
After this you can boot any operating system from your pen drive and install it or run as a bootable OS.

In this example i am considering that my pen drive name is disk i:

go to run and type "cmd" and right click it to "run as administrator"

start entering the following commands in a sequence

  • diskpart
  • list disk
  • select disk 1  (considering that in the list of disks your pendirve is disk 1 or choose accordingly)
  • clean
  • create partition primary
  • select partition 1
  • active
  • format fs=ntfs
  • assign
  • exit

After following these steps you just have to copy the setup files on your pen drive either from an image file or from where ever you have stored . Just restart and set the boot option to boot from USB drive.
