Installing a copy of French Windows 7 alongside the current English

I would like to purchase and install another copy of Windows dedicated entirely to French. I know that I need an additional license, and my question is about how to install it and on which drive? I already have a dual boot Windows 7 and Xubuntu. Also, I am planning to transfer the current C: drive and the new OS drive to a 250GB SSD.

My current setup is a single 500MB Seagate SATA 3

C: current boot drive: drive 80GB
D: 50GB data
E: 60GB data
F: 60GB data
W: 90GB data
Ext4 25GB Xubuntu
Ext4 42GB data
Ext4 42 data
Swap 6GB

You can install it on any drive or partition you want. It should be at least 60 GB.

Personally if you have room in your box for another drive, that`s what I would put it on.

Use a Solid State Drive, they are cheap :)

A separate drive (SSD if possible) would be my preference too. Make sure to disconnect the other disks when you install the French version on the new disk. Then access the different systems with a change of the BIOS temporary boot sequence.

Another option is an installation in a virtual partition. That has a lot of advantages. Here is how.

Thanks to you both for the info.
