​Unlike Ubuntu which I think can find a way to make space within the
windows partitions to install itself, I don't think Debian has that option.

I am not sure if you would need to reinstall Windows and reduce the
partition sizes to create free disk space that the installer will see and
make use of.

Perhaps if you nobble the two recovery partitions that won't make Windows
unusable.  If you could then install debian in the space freed up when you
reboot into Windows it will discover that the recovery partitions are gone
but there is no space in which to recreate them.   I think that Windows
might then reorganise things to reduce the C drive partition size and allow
new recovery partitions to be created. I am not 100% sure on this but you
could google it and check.
