Installing Snow Leopard on 10.5.8 macbook.

Question

I was trying to install snow leopard on 10.5.8 white macbook. It would not let me.
I found a thread that said boot from disc - partition drive setting aside 5GB to install snow leopard- and it will work to install to the other ~75GB, or whatever. I've since lost thread.
Disc Boot would still not install Snow Leopard.
Somehow i'm at Restore Your System with no time machine attached though. My OSX has been erased when i partitioned drive. Now I have no where to go. I can't eject disc.
I'm at the starfield. My top menu has
-Mac OSX installer
-File
-Edit
-Utilities
-Window
Can anyone help me install snow leopard or get the disc out or do something so i can have this comptuer back? I am on separate macbook pro so i can use this for now. thanks

What exactly do you want? Is it to upgrade Leopard or do you want to make a separate Snow Leopard partition?
Five ways to eject a stuck CD or DVD from the optical drive
Ejecting the stuck disc can usually be done in one of the following ways:
1. Restart the computer and after the chime press and hold down the left mouse button until the disc ejects.
2. Press the Eject button on your keyboard.
3. Click on the Eject button in the menubar.
4. Press COMMAND-E.
5. If none of the above work try this:
Open the Terminal application in your Utilities folder. At the prompt enter or paste the following:
/usr/bin/drutil eject.
If this fails then try this:
Boot the computer into single-user mode. At the prompt enter the same command as used above. To restart the computer enter "reboot" at the prompt without quotes.
To resize the drive or add a new partition:
1. Open Disk Utility and select the drive entry (mfgr.'s ID and size) from the left side list.
2. Click on the Partition tab in the DU main window. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. +(Note: You can only make a partition smaller in order to create new free space.)+
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
