Steps to create a NTFS partition
Before we change partitions of our harddrives we need to make backups to be able to restore our data in case something goes wrong.
2. Shrink an existing partition
In case we don't have an unpartitioned space on our drive we need to make some space for the new partition, else proceed with step 3:
3. Create a new partition
In case we have an unpartitioned space on our disk we can partition ii with the disk utility or run gparted (we need to install it only when we are not running a live session) to select the unpartitioned space. From the right click menu choose New:
Select ntfs (or any other format) from the File System dropdown menu and optionally choose a sensible label for this partition. Click the green tick to proceed.
