Every recovery CD has an automated installer for easy deployment. Please start your computer and enter the BIOS mode. From there navigate to Boot order and make the CD/DVD-Rom as your primary booting device, then insert the 1st recovery CD/DVD and restart your computer. After this process the computer will boot the CD and start the installer. Follow the on-screen instructions to properly restore the operating system. When it prompts to insert 2nd CD, remove the 1st one and do it as it asks.
