If your partition you have extracted the iso files are the second partition use (hd0,2)
On the EasyBCD -> add New Entry -> niroGrub - Install
Use easyBCD 2.2 the version 2.3 have some problems I solve the installation problem doing install windows xp and one partition of 32GB, create one partition for Remix OS with 23Gb and extracted the iso files, and another partition for save files.
