I have to install Windows 10 Pro in a bootable hard drive of about 1Tb (model WD10EARS), formatted like this: first an 850Gb NTFS partition with data, and then 150Gb of unallocated space. My aim is to install the copy of Windows 10 in the unallocated space, keeping untouched the partition with the data; is it possible?
(Edit: no operating system is currently installed on the disk)
