Yes under GPT the size limit is a lot more than the 2,2TB under MBR.kemical , I had a 10TB drive on gpt . I do have another drive , format the drive to gpt . Sounds dodgy someone on the dark web will be able to change it back to mbr just for laffs .
It's always worth a try I guess.My hard drive is the most perfect hard drive there,s ever been , I use a dvd to load windows . And it always ends up as mbr , would it make any difference if I use a usb drive if I still have one with widows on . And take my serial number from the dvd to activate .
