Windows only boots from primary partitions (sda1 thru sda4) formatted NTFS with the boot flag. If a second install of Windows, the second install will move all its boot files to the install with the boot flag.
Windows does not see Linux partitions and sometimes it partitioning tools do not rewrite partition table correctly. Best to backup partition table and all your data first.
With gparted create a NTFS partition for Windows to install into.
Is your system new enough to also boot with UEFI. You must have all systems installed in BIOS mode or all in UEFI mode.

To get each MS to have its own boot loader make a primary NTFS partition and set its boot flag on, then install the 2nd product in it. Multibooters, Pictures here worth 1000+ words

I do not think Windows is seeing any place to install, so it cannot do anything. Or perhaps your Windows install disk is not written correctly.
Also is it a full install or a recovery disk. It has to be the full install to work. Recovery reinstalls just erase drive and restore it to exactly as purchased.
