Step2: Mount the ISO image in any Virtual CD/DVD tool (like: DemonTool, PowerISO, etc.).
Setp3: Double Click on the CD to run the Autorun and choose Install inside Windows.

Step4: Choose the drive you want to install Ubuntu inside it (don't worry it will never format or change the file system), and the size you want to assign to Ubuntu (recommended 8GB), Username and Password (is required), and press Install.
Step5: After Windows reboot and the boot option appears [lease choose the Ubuntu and just relax and let the thing work, it'll reboot and Boom you have Ubuntu on your PC.
