I hope your Windows is booting fine. Did you mean those partitions were created earlier when you installed Mint or you installed them now?
I will try to explain my understanding -
The MBR (Master Boot Record) holds the information of OS'es available in your system. Now this can be handled by either Windows Boot Loader or GRUB (Boot loader of Linux Mint). As explained in the tutorial, GRUB could be installed in a seperate partition or written to MBR. Advantages and disadvanatges are explained in the article shared earlier.
1. You can make Windows boot loader to boot all other OS'es in your system. (Using entry in EasyBCD)

- Installing latest EasyBCD helped StevePMo. You could give it a try.
2. If GRUB is installed to MBR, then GRUB will automatically reconginze the other OS'es available in system and list them as options.
It is strange that you're getting Windows related error when you select Mint. Probably others who have experienced similar issue can help.
