How to make a Bootable USB

Make a Bootable USB


A Bootable USB: Utility to Create Bootable USB Drive to Install Windows Vista, Server 2008 and 7
Imagine a situation where you need to install Windows Vista or 7 in a system but you don't have access to DVD drive. We all know Windows Vista, Server 2008 or 7 comes in DVDs and you'll need a DVD drive to install them. Then how will you install them? The solution is, you can create a bootable USB drive which can be used to install Windows without using DVD drive.

I have posted a detailed tutorial to create such bootable USB drive long time back, you can read about it here.

The above method is very easy to follow but wouldn't it be great if we can use a utility to do the whole task automatically? Our reader "Aris" has created a small utility exclusively for AskVG readers which creates a bootable USB drive to install Windows Vista, Server 2008 or 7.

Prerequisites:
A USB Drive (4 GB or more)
Windows Vista, Server 2008 or 7 ISO image or DVD
Host OS: Windows Vista (SP1 or SP2), Server 2008 or 7

How to Use:

Once you meet the requirements, run the utility. Its a portable utility so doesn't need installation. Simply run it and check the option "I have read and accepted the following License Agreement". Now click on OK button and it'll launch the main application.


It also shows a Help window so that you can use the utility easily. The utility requires only 4 easy steps to follow:

1. Check USB drive (To check whether your USB drive is attached or not)
2. Format USB drive
3. Choose DVD or ISO image (To A Bootable USB: Utility to Create Bootable USB Drive to Install Windows Vista, Server 2008 and 7

Using Physics to Understand Your World

Using Physics to Understand your World


Studying motion is fine, but it’s just the very beginning of the beginning. When
you take a look around, you see that the motion of objects changes all the
time. You see a motorcycle coming to a halt at the stop sign. You see a leaf
falling and then stopping when it hits the ground, only to be picked up again
by the wind. You see a pool ball hitting other balls in just the wrong way so
that they all move without going where they should.
Motion changes all the time as the result of force, which is what Part II is all
about. You may know the basics of force, but sometimes it takes an expert to
really know what’s going on in a measurable way. In other words, sometimes
it takes a physicist like you.


Absorbing the Energy Around You

You don’t have to look far to find your next piece of physics. You never do. As
you exit your house in the morning, for example, you may hear a crash up the
street. Two cars have collided at a high speed, and, locked together, they’re
sliding your way.

Thanks to physics (and, more specifically, Part III of this book), you can make
the necessary measurements and predictions to know exactly how far you
have to move to get out of the way. You know that it’s going to take a lot to
stop the cars. But a lot of what?

It helps to have the ideas of energy and momentum mastered at such a time.
You use these ideas to describe the motion of objects with mass. The energy
of motion is called kinetic energy, and when you accelerate a car from 0 to
60 miles per hour in 10 seconds, the car ends up with plenty of kinetic energy.
Where does the kinetic energy come from? Not from nowhere — if it did, you
wouldn’t have to worry about the price of gas. Using gas, the engine does
work on the car to get it up to speed.

say, for example, that you don’t have the luxury of an engine when you’re
moving a piano up the stairs of your new place. But there’s always time for a
little physics, so you whip out your calculator to calculate how much work
you have to do to carry it up the six floors to your new apartment.
After you move up the stairs, your piano will have what’s called potential
energy, simply because you put in a lot of work against gravity to get the
piano up those six floors.

Unfortunately, your roommate hates pianos and drops yours out the window.
What happens next? The potential energy of the piano due to its height in a
gravitational field is converted into kinetic energy, the energy of motion. It’s
an interesting process to watch, and you decide to calculate the final speed
of the piano as it hits the street.
