Ok so I wanted to reinstall windows and downloaded the windows media tool, installed it on my usb flash drive and booted from it. So far so good. I selected my drive and it said you can’t installed it the because its a GPT drive, tried both drives. For some stupid reason I decided to format it and erase my windows 10 which was usable. Now how do I convert my drive from GPT to UEFI from the BIOS if possible? I have a Gigabyte motherboard.
