Restricted Partition Resize Issue

[Owlservice]

Good morning,

I have bootcamp installed, but I've decided I need more space on that partition.

In disk utility, I have followed the protocol of creating an additional partition within my MacOss. This is where I get a little confused.

On my MacOss partition I have 299gb of free space. But on the new partition I create I can only make that new partition 26.4gb.

Does anyone know why this is?

I am at a loss.

Thank you.

Think of it this way, Partitions are slices of your disk, Free space(the 299gb you mention is whats free in that macos partition.
From that picture, you have 2 partitions, one for mac (375 gb), one for bootcamp (99gb), and some unused space, which it's trying to make a new partition in.

If you want to increase your bootcamp partition, rather than making a new partition, you need to grow the existing partition into it. If you want to free up some space in the mac partition - shrink the mac partition. That frees up space to either make a new partition, or grow an existing one.

Can you do that now?
When I was using bootcamp it was not possible to resize the bootcamp partition at all. Well, you could do it but Windows wouldn't boot afterwards.
Has that changed now?
