I have installed win10 over a dozen times on 6 different hard drives and never had this Issue, relly need help understanding what has changed. I have always booted efi, I have not formatted a disk fat32 since windows 7, why am i suddenly now unable to install windows 10 without it complaining my partition is NTFS and needs to be formatted fat32? New hard rive, ol drive doesnt matter. i neve format them. I hit new and let windows do parttion the drive how ever it wants. i hit next and i get the error message when it tries to copy files. Why has this never happened before? I am currently installed as non efi but now i cant see my old drive with all my stuff .
