Great, this is not very hard to do, I just wanted to make sure of your preferences.
Windows Drive Management Utility does not recognize the ext3 file format used by Ubuntu so it will not show up there. But unless you did remove it, it is still there where Windows says it is unallocated.
Here is what I suggest to you to do: First, shutdown your computer and move the SATA hard drive cables, plug the 500GB hard drive where the 320GB is now, and the 320GB where the 500GB is now. Master and Slave were necessary for IDE hard drives that shared one (wide) connector cable, but SATA only uses one cable (and connection) for each hard drive so there is no Master or Slave with SATA. Doing this will put the 100MB boot partition first in your hard drive order in the bios and will make it easier to setup the Windows bootmgr, later.
Next, boot to your Ubuntu install CD. You can use the Live CD and GParted to look at the 320GB hard drive partitions to see if Ubuntu is still there.

Then you will need to reboot, and this time select to boot to a hard drive and select Ubuntu. This should put you in your Ubuntu partition where we can reinstall Grub and use it as the boot menu. I need to know what version you installed before giving you the "terminal" commands. For an idea of what you will be doing, please have a look at the "Restore Grub" link at the bottom of my post. This is for Ubuntu 9.10, which uses Grub2 and is different from earlier versions. If you want Ubuntu 9.10, you can just download the install CD from Ubuntu and install it in place of your current Ubuntu (if you do not need to save anything there) and Grub2 will install automatically.
Let me know?
