Can someone assist me with bootcamp? I have an early 2011 macbook pro (A1286) that I would like to dual boot with high sierra or big sur (opencore) and any version of windows. Everytime I attempt this the install stops saying that the drive is mbr and needs to be gpt. I can't fix this since bootcamp did all the formatting. The one time i formattedbthe drive myself i got windows installed and when i restarted my macbook something messed up cause I could not boot into windows again. Can someone tell me what I'm doing wrong?
