Broke my mbr

I have a windows 10 PC and I have been trying out Linux, it annoys me that it boots to Linux by default and I was going to delete Linux anyway so I tried the instructions here Fix the MBR – Guide for Windows XP, Vista, 7, 8, 8.1, 10 and well it broke it. When I boot all I get is operating system wasn't found. Try disconnecting any drives that don't contain an operating system. What do I do? When I tried the instructions I could see it there. I'm sure I picked the right one etc. Thanks for the help
