I can't say I've ever dual booted Linux with BCD (without grub), I used it for osx86. In that case, you pointed BCD to the partition osx86 was installed on and to a chain loader file, chain0 I think. I do know this can be done with Linux though. If using UEFI, you would likely point BCD to an .efi file on your android partition. If using MBR, you might have to image the boot sector on your remixos partition (using dd for example). Name that image boot.bin or something and point BCD to it.
I guess you are not using UEFI, as there is no EFI partition. How won't Remix boot even you added it to the Windows boot loader? Is GRUB installed to the remix partition? (it may be overwritten by windows)
