UPDATE 9/13/14 the other computers has a (probably 7200 rpm) traditional spinning hard drive of 500 GB, and then there's an 87 GB ssd which has nothing on it. One of my other computers has a 500GB drive and I'm not sure it has another one. My computer has one 179GB disk and then a 150GB disk which barely has anything on it. If you have 4 250GB disks, that's equal to 1 1TB (1 terabyte) drive.

It will analyze your computers processor, memory, storage. Here are the size of the Windows folder of my several systems: 1. large is always better than insufficience. So you only need about 15, but I'd go with large disks, like 150, or 250, or 500, or even 1000 GB, which is a terabyte. Since it uses the same system requirements as Windows 7, you might consider upgrading to. Thus we need to give the system drive a large-enough disk space.

The error message that I got when I had an 8GB virtual disk was something like 'Windows needs 9.(a bunch of numbers) to install'. I increased it to 10, and it worked but barely had any space left on the drive.

I've tried in a virtual machine with Windows 7 32-bit (SP1, I think), I had an 8GB virtual disk and it wouldn't install. I am thinking of getting a solid state drive to import windows 7 onto and just use it for that and nothing else so theoretically my computer will start quicker but how much space minimum do you guys think should be best for this? like I Don't want to waste coin on space I'm not going to use. Windows 7 Recommended Requirements CPU: 2 GHz or faster RAM: 4 GB HDD: 100 GB of storage space GPU: Integrated GPU from Intel HD Graphics/Iris Graphics.
