I got a new hard disk (750GB) and I'm planning to install 3 OS there namely Windows 7, Ubuntu (13.10) and Kali. I've done dual booting before with Win 7 and Ubuntu but I never tried adding another OS, triple booting.

Should I install Win 7 and Ubuntu first then Kali or what should be the order? I planned out the following hard disk space as follows

Windows 7- 100gb
Ubuntu 13.10 - 50gb
Kali - 50gb

Hoping for a reply or tips thanks!
