I downloaded the Fedora 26 Media Creation tool, made my USB bootable, and then installed Fedora 26 onto a partition I had made on my boot drive. I booted into Fedora, selected the free partition and downloaded Fedora.
However, I can't boot into Windows now. I googled around a bit and it looks like I may be in Legacy Boot mode? I tried changing settings in my BIOS from Legacy mode to UEFI. But when I switch the settings to UEFI I get no bootable device. I know my windows installation wasn't erased because I can still see all the files and directories on that partition.
My bios options are Storage Boot Option Control and Boot Mode Selection for differentiating between Legacy and UEFI
