Can't boot from DVD-R (Lenovo H50-50)

[adamhunter]

I disabled Safe boot and all that, and can select my DVD-R from the boot menu,but all it does is hang for a little bit and then just boot up windows 10. I'm trying to install Windows 7 SP1. Help?

Where did your Win 7 install disk come from? How was it created?

I purchased it off Amazon.
