Hello. I have recently been having some problems with my computer and so I thought that reinstalling windows would be a good idea. I downloaded windows 10 boot installation media and at the time I didn't have a USB to install from. So I used the ISO option and attempted to reinstall from desktop. When I got to select the drive, it said it was in the MBR parition type and it needed to be of GPT partition. I then opened cmd whilst in windows 10 setup, entered "disk part, list disk, select disk 0, clean, convert GPT". This then caused the drive I wished to install windows 10 on to dissapear from the menu selection. I then exited out of the windows 10 installer to find that my drive will no longer show on file explorer. I checked BIOS to see if the drive was showing and it was, so now I am stuck as to what to do to get it to re-appear so it is now useable. Any ideas? Thanks.
