I have a laptop running Win7 on its internal drive, and I have installed Ubuntu (13.10 64bit currently) onto an external USB drive. Other than Ubuntu hardware compatibility (Mouse button presses are not being responded to) issues, everything's working fine. To load Ubuntu, I created 3 partitions, '/boot', 'swap', and '/' (in that order) and used EasyBCD to setup my boot menu.
What I would like to do now is setup a number of Ubuntu versions on another (blank 500GB) external USB drive as I've had hardware related issues both with 13.04(32bit) and 13.10(64bit). So I want to try out 12.04LTS, 13.04, and 13.10 with 32 and 64 bit versions of each, and see which runs best.
The problem for me is that I'm not sure how to partition the drive to achieve this.
I understand that I can have one '/home' and one 'swap' partition that will be shared by all the installs, but what about the other partitions?
I will need to setup an extended partition with logical partitions inside, to accommodate so many installs.
Do I need a '/boot' partition for each install? Do I need a '/boot' partition at all? I know I need a '/' partition per install. What order would work best? (Swap 1st, then all the installs, and home last) or (Swap 1st, then home, then all the installs) or (some other arrangement)
Any advise would be much appreciated.

I would have liked to have been able to create a new tag for multi OS installs beyond the usual 2, eg 'OSx3+' or something. (Not enough reputation to do so.)
