Hassles trying to install win 10

I gave up on trying to upgrade  my Optiplex 9010 to win10 because of it crashing from not enough internet. I got a Del reinstall disk, and deleted the C drive stuff from the hard drive. When I have done this before it detected the CD/DVD and installed it. This time it says I have no operating system.

Is there a setting in my bios, or can I use my flash drive to put a file there so it loads? With all those options it should go

Thank you in advance for your help
