How to make a Virtual Machine Box

What is VM Box?
VM Box is a Virtual Machine and it is basically another PC inside your own PC.
What's the use of it?
The use of a VM is so you can test if files are safe and not infected by a virus. You can also use them to see if your infected server works and you may not of wanted to test it on your own PC.
Anyway, Let the tutorial BEGIN!
Step 1) Go onto VM Box's Website which can be found Here
Step 2) Go down on the left hand side and select 'Downloads'

Step 3) Now select what operating system you are on and download it.

Step 4) Go ahead and download the VM Box file, Then drop it on your desktop.
Step 5) Setup everything and you should get this screen

Step 6) Now we need to obtain an Operating System. Let's put windows 7 on the VM, Be aware that a OS will be around 3GB+. The download for this Windows 7 And more is Here.
Step 7) Ok, We're almost there! Now select 'New' Then hit on 'Next'

Step 8) Now select name for your VM and select your OS Platform and whatever version of it you downloaded. Because I've downloaded Windows 7 for my VM Box, Im going to select that.

Step 9) Now you get a screen like this

Select / Drag how much RAM you want to be used up when running your VM, Im going to use 3GB or Ram because that's half of my laptop's ram.
Step 10) Now put the same options as here

Ignore the 'Use Existing Hard Drive' That was from my old VM.
Step 11) Select the first option on here then select 'Next'

Step 12) Now, This bit is up to you, You can either have Fixed Storage (Where you set an amount of GB you want to use on the VM) Or you can select Dynamic Storage (Where if the VM's HDD gets full, It creates more space) But for this tutorial, Im going to be using Dynamic Storage.

Step 13) Now find a place where you want everything for the VM to be stored, I suggest making a new folder.

Step 14) Now select the amount of space you want to be used up by your VM, Recommended is 25GB but you can ofcourse change it.

Step 15) Now select 'Next' and then 'Create'
Step 16) Now, Click on 'Start' then click 'Ok' For the options that come up.

Step 17) Now click on 'Next' when a first run wizard appears.
Step 18) Now you will see this

Step 20) You have succesfully setup your VM, Enjoy.
