Your problem is that you selected to install Grub code to sda1 which is a windows partitions, your system partition. This has overwritten the windows boot files for windows 10. I saw a post here yesterday from someone who had done the same thing with the same result. You may need the windows installation medium for this to repair this. Not sure what else you could do but I'm sure others who are more familiar with windows will have suggestions.
