I am trying to install Windows 10 off USB bootable onto my 4TB Seagate SSHD. Doesn't not seem possible for me to do. If the drive is GPT then Windows 10 just refuses to install. Says it can't do it. Put drive into MBR, the drive is split into two unallocated partitions, because of limitations to do with MBR format, I guess. Anyway Windows can't install that way either because there are two partitions, I am given error code 0x80300024. Anyway to make this work at all? I don't know what to do. I have been at it for a few hours and I given up. Any help is much appreciated.
