Hi, I'm currently having the same problem while trying to dual boot Backtrack 5 with Windows 7 Home Premium. I'm using Gnome 64-bit and running it off a live cd.

I'm not seeing the "Install them side by side" option.
I've read that a possible reason is because I already have 4 partitions, but another computer I tested also had 4 partitions yet had the option.

Suggestions/Opinions? Thanks in advance!
And while I'm at it..as you can see the first picture shows that I have Windows Vista partitions, but this is a brand new laptop I ordered last month that came with Windows 7 Home Premium installed..does anyone know what the reasoning behind this could be? The second computer is also Windows 7 Home Premium (also bought last month) but the Vista partition is only for the Recovery.
*Sidenote - I took the pics with my camera before figuring out I had to install gnome-utils for printscreen to work.
