df is used to look at partitiions and if you did not make a /boot partition then the folder boot is under the / partition.
Now I am not entirely sure how to advise you as you don't say why you are afraid to use a linux bootloader.
lets assume you are easing yourself in, then its ntldr in mbr and that then points to a linux boot loader that chainloads into linux.
Otherwise you use (eg) grub in mbr to get into linux and that then points to ntldr files on your C drive to boot windows. also known as chainloading. Your choice. Have a bo peep at both if you care to here
keeping windows bootloader is my way of talking about ntldr.exe but there is lots on grub.
