I don't have time for details, but here are the bones of it:

  1. D/L ISO image of your Linux to Win desktop
  2. D/L Virtualbox; install it on Win.
  3. Start Virtualbox; go through the process of creating a VM (menu: Machine -> New etc)
  4. You should have a new (empty) VM now.
  5. For your new VM, go to Settings -> Storage. Under IDE controller, you should see something like a CD icon and the word "Empty". Click the icon or the word "Empty".
  6. This will now grant you the ability to add a file to your virtual CD/DVD device. Use the folder icon to select the LINUX ISO image that is on your Windows desktop. This will mount the image.
  7. Close the Settings dialogue
  8. Make sure your VM is selected (on the VirtualBox main screen). Click "Start". The Linux ISO file should mount and your Linux should start installing into your VM's virtual HDD.
