How Windows partition disk (that has other partitions) during install?

[kukt65]

I have 2 primary Linux partitions. I want to install Windows 7 and than Windows 10 after Linux. I know that when you are installing Windows on disk that has 3 primary partitions, Windows automatically mark 4th partition as extended and proceed with installation because Windows creates two partitions (C: and recovery). Will Windows 7 during install on my two primary partition disk create another two primary partition and make rest of space unusable or what?
