First thing we do is back up any data you needed to save. You will need a valid copy and serial no. of the operating system you need to install. Insert the disc into the computer and reboot at this time. The computer then will find the disc and you will see a new screen asking if you want to install the new system. Yes, and then a screen will prompt you to select the drive you wish to install on
. and ask if you need to format. Answer yes. Then follow the written instructions that appear on the screen. You will have to accept the install before it will start.You will be fine now.Reference.http://tinyurl.com/yfxbf6g
