Splitting EXT4 Partition Into New NTFS Drive

[LanciaDelta]

Hello, I'm having trouble trying to split the EXT4 partition to have a 2nd NTFS partition to install Windows on it. I thought this would be easy but it won't let me do it. Any suggestions please? thank you

What instructions are you following and how is the sequence failing ?

well I'm a novice in Linux just FYI, from what I'm reading I can create a USB stick with Ventoy on it with many distro loaders and that will give me the option of doing it in a live version virtually whereby I can then cut up and reformat (into whatever format I want) the existing internal drive and then install Windows on it, is that correct? thank you.
