I am trying now to restore the factory settings with ALT + F10 which is not working any more. Each time its giving me screen to choose operating system. How do I restore my system now?

You can create a Windows-compatible partition using the GParted application that is included in the Ubuntu live USB. Use GParted to format the entire drive to NTFS with the boot flag set to bootable. Then you can reinstall Windows 7 from the factory default image of Windows 7 that you have burnt to a DVD. For more information see: How to remove Ubuntu and put Windows back on?.
It is always a good idea to install Windows before you install Ubuntu. When you install Ubuntu and get to the Installation type screen in the Ubuntu installer, choose the option that says: Install Ubuntu alongside Windows 7. This option will install Ubuntu alongside Windows 7 in a dual boot layout so that when you start the computer you can select to boot to either Ubuntu 14.04 or Windows 7 from the GRUB boot menu.

I assume you want to delete Ubuntu and restore Windows to original state (factory settings)? Note that I'm not familiar with Vaio, however on boot screen (grub) you should be able to see installed systems. For Windows you should have more than one entry and the first one
