Yes. Use GParted on the 'live' USB of Ubuntu to shrink the ext4 partition(s) to create unallocated space. When you boot the windows installer, immediately after the licensing agreement page for windows, you will see install options and select the Custom option which allows you to select a specific partition or unallocated space.So can I just partition the ext4 disc with gparted and then install windows. Ideally windows will install on the open part of the partition.
