How do I install Ubuntu Linux to my PC when I have two Hard Drives and don't need to partition?

I've been looking at the Ubuntu Linux site for a while, they tell you how to partition a drive, but not how to set it up for two HD's with a choice of which to boot on startup.

I know I could have the BIOS always pop up on powerup, but is there an easier way?

Yes.

Tell the Ubuntu installer to install on your second drive and allow it to use the full disk. Install GRUB ('Advanced'-button on the installation summery screen after the partitioning phase) on your primary drive.
Now at boot-up you get an automatic choice beween Ubuntu and that other os
