Fix my server from Hetzner so that ALL 10 hard drives appear in Windows - Instead of only 6.

Hi, I have a dedicated server which I am leasing from Hetzner. When I originally logged onto the server via SSH (rescue mode), I could see that the first 6 disks registered properly, but the final 4 disks said "Disk doesn't contain a valid partition table". Using my very limited knowledge and a bit of Googling, I tried to fix these myself, by creating new partitions and labelling the table type as "Windows Reserved". I hoped that this would solve the issue, but it didn't. Still only 6 disks appear. Since doing 'what I done', the message "Disk doesn't contain a valid partition table" no longer appears when logging into SSH. I have installed a couple of different versions of Windows: Windows 10 Pro Windows Server 2012 R2 (Still currently installed). Both times, Disk Management could only see 6 available disks. I believe the issue lays within SSH, but due to my lack of knowledge... I don't know how to fix it, and get the final 4 disks to appear in Windows?? Could someone please help me. Thanks
