I made a bootable windows flash drive of window 10 using bootcamp on the same ssd i have installed el cap and it restarted mp so i can install windows on bootcamp partition somehow the the installing process stopped and system restarted. I tried to install win 10 using bootcamp so i wont be surprised if theres any incompatibility or bug with my mp. Been a while since im trying to switch to windows because of compatibility issues with my favorite software and etc.
