Create Bootable USB

Ever wondered how to boot windows 7 off a USB...Well here on Eazy Tech I'm going to explain to you how to exactly make an operating system such as Windows 7 boot of a USB. You will need the following pieces of software and hardware.

1. 4gb memory
2. PowerISO

• Open command prompt. Simply do this by going Start>Run>type cmd. This should bring up command prompt (black box)
• Type diskpart. Having done this it should bring up another command prompt labelled c:/system32/
• From here you want to type list disk - This list the avaliable disk on your system
• Select your USB which. By doing this type 'select disk#'
• Type clean - This cleans your USB.
• Next you have to create a partition for your USB. This is done by typing in 'create partition primary'
• Having done that you need to select that partition by typing 'select partition 1'
• You then need to make the USB active, this is done typing 'active'
• Your USB will then need formating this is done by typing 'format fs=fat32' having typed this, the process of formating your USB can take between 5-10 minutes.
• After the USB has been formatted you then need to type 'assign' this reassigns the USB drive giving it a new drive letter. An example of this, could be that your USB drive letter was J and having typed 'assign' in the command prompt it changes its to K.
• Once you have assigned the drive you need to then type exit. This exit's the diskpart command.
• In order for you to make the windows 7bootable you can use a virtual drive, in this case you can use a program called PowerIso. Having downloaded the trial version you can then mount the file that you will be copying to your USB
• The last stage that you need to do is write the following code in command prompt. Note that the last step was that you exited the diskpart command so you should be in the normal c:\user\. Here it should look like this c:\windows\system32>xcopy d:\*.* /s/e/f  j:\

As you can see above I have posted a youtube clip that basically explains everything that I explained above.
