new partition doesn't show in startup disk utility

I wish to migrate my Time Machine backup of my MacBook Pro running Mavericks to my MacPro tower and have a dual boot system, alongside its original operating system, Snow Leopard (10.6.8).

I created the 2nd partition on my MacPro tower by using Disk Utility on the DVD installation disk. I did not erase and partition, overwriting 10.6.8, but instead I divided the current drive into two partitions. But now, when I'm in 10.6.8, the Startup Disk utility cannot see the 2nd partition. What it does see is the DVD running the installation disk, the 10.6.8 partition, and it displays a network icon with a "?" inside. On the MacPro tower's desktop, the 2nd partition is displayed as a folder.

It was my understanding that when I selected the 2nd partition as a startup disk, a reboot would trigger use of Migration Assistant, and that I could then select my Time Machine backup so it would install Mavericks and associated applications. Please help me find my 2nd partition.

Thanks,

MacBook Pro, OS X Mavericks (10.9.4)

You need to install an OS on the second partition before it'll show up; for a Mac OS X 10.8 or newer Time Machine backup, this can be done by connecting the drive containing it, restarting from the drive's recovery partition, and using it to restore the backup.

10.6.8 does not have a recovery partition. So if I can't see the new partition, I can't set it as startup disk. If I can't set it as startup disk, then how do I get Migration Assistant to run?
