EasyBCD Dual Boot Windows 10, Linux Mint 17.3

my Dual boot was working fine. When booting Grub2 would appear and option to select Mint 17.3 and Windows 10. When windows 10 was selected, it would go to windows 10 boot loader and option to select windows 10 or linux Mint.
So, I modified windows boot loader using easy bcd to load windows 10 only.
But now, when windows is selected from grub2 menu, I get an error to install windows cd and repair OS. But when I insert the Windows 10 CD, I only see the Linux partition and nothing to repair.
