I tried to install Windows 10 OS on my Windows 8.1 laptop. I got to the drive selection screen, and got this notice that my choosen drive is in MBR format. Windows 10 needs GPT format. I THOUGHT THAT FORMATTING THE DRIVE WOULD CHANGE THE FORMAT. It didn't, and now my laptop cannot enter windows. What should I do? (My laptop was partitioned into 3 drives, I only formatted the C drive. Most solutions will delete the WHOLE DISK, and I don't want that)
Thanks so much beforehand
