If it's MBR partitioned, you're already using up your four (4)
partitions (OS (C:\) ; Recovery(400MB); RECOVERY (D:\); Recovery
(800MB); and I'm not 100% sure if the EFI partition counts against you

You would need to remove some of those partitions, and set up an extended
partition container in order to create logical partitions which you can
then install Debian to.

​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.



Though, since you already have four (five if we count the EFI
partition), perhaps the drive is already GPT partitioned ...
