Can I install macOS with OC on MBR?

I just built a fully functional oc, which is a dream come true for me. BUT, i cannot be that fantastic so i just found out that the hdd im using is partitioned with mbr, but my mom still has some things there (as it is her old laptop) and we have nowhere to put them, so I cannot repartition it. So one option is to buy a new hdd or install it on the mbr somehow. I also found some utility named easymbr, but I do not know how to implement it into oc. Any helm appreciated. Thank you.

(Sorry for my english. Im still super excited)
