Grub can do that.  Doing it from the installer will require command-line 
use and familiarity with the tools:

Instead of dual-booting, I recommend using VM software.  VirtualBox is 
free, does not require any messing about with existing partitions, and 
allows the VM client to run at the same time as the host.

I'm fairly sure that the installer will install to a partition if one is 
available or created with the partitioning screen.  It will still be up 
to the user to install boot0, which of course only works with MBR 
primary partitions.  The four-partition limit of MBR often means that 
the ugly partition-with-a-partition format is required:
