im trying to do a factory reset, but sytem will not regognize the dvd

Hi, I hope you can please help. Last year when windows 10 came out.... I kept getting notifications from window to download 10 until they gave me no option and I had to...Then my laptop started having tons of issues and I never had any problems before this. So I uninstalled windows 10.....since then my laptop would not successfully run any updates, will not open most things... only opens the internet and office 7. I get messages with tons of numbers and the most common (explorer.exe server execution failed) when ever I try to open anything. I want to do a factory reset or recovery, as I have the DVDs, and all the software to set the laptop back up to before windows 10. Plus I also have a second hard drive with windows 8 already installed if this one is too far gone. Along with the laptop not opening anything - like the control panel, or My Computer , when I right click on the start button it doesn't give me the option run or anything, I can not get the laptop to auto start or run the DVD drive to start the recovery. So how can I do it? any ideas?
