I have a G4 Imac running 10.3.9. I have the Leopard DVD but my drive does not read it. I purchased an external DVD (usb) drive for the install. I click on the install, give my password but it come back to the computer sign in when it reboots. Is there another way to upgrade the opsys?

You need to use a FireWire DVD drive. Return the one you bought.

After you install the base 10.5, download & install the 10.5.8 combo update at http://support.apple.com/downloads/Mac_OS_X_10_5_8_Combo_Update
The DVD should look like this
A gray DVD from anothjer model Mac won't work.
Caution - Leopard does not support classic mode. So, if you currently open OS 9 apps in classic mode, you won't be able to do this if you upgrade to Leopard.
