How do I dual boot 2 windows 7 and a windows 10?

[Mikerosoft]

I need help dual booting windows 7 ultimate 32 bit and windows 10 32 bit. Note I have already done this but I want to install another Windows 7 32 bit. This is the setup that I want (Windows 7 Home Premium 32 bit + Windows 7 Home Premium 32 bit + Windows 10 Pro 32 bit)
Why Do I want 2 windows 7 "oses". Well because I am going to use one for testing and movie making and the other one for just normal use. Note I don't want to use virtual box, vm ware or any others. Help Please!!

Thanks

How many drives are you gonna use ?

1 ?

If so I would install your 1st OS to unallocated space in Legacy mode on a MBR drive.

If you already have 1 instance of W7 installed, then just create 2 more partitions for the 2nd W7 install and the 3rd for W10. (Those 2 partitions could be Logical partitions)

Partition Wizard is the simplest way to do it.

or

Free Partition Manager Software - AOMEI Partition Assistant Standard


But before you proceed, please post a shot of Disk Management.

Personally, I would never put W7 and W10 on the same drive.
