MBR (Legacy) has a limit of up to Four Bootable systems. However, EFI with GPT can manage up to about 128 partitions.
According to your post, you are using EFI.
On Windows, did you make sure to disable "Fast boot" or "Fast startup" from Control Panel > Power Settings, first? Fast boot locks the hard drive, preventing full installation of the Linux OS.
In the BIOS Settings (motherboard), secure boot should be disabled for ease of install.
