Hello,

 

I just wanted to upgrade my Mac OS from Tiger 10.4.11 to a Leopard 10.5 (I run PowerMac G5 Dual 2.0GHz) and I experienced a little problem. To boot computer from the genuine retail Leopard 10.5 DVD I am suppose to hold down the 'option' or 'c' key while restarting computer. So I do it and what only happens is the little icon representing my main hard drive called Macintosh HD appears in the center of the screen and an arrow button (which after clicking it starts my OS previously installed) and also 'refresh' button ( an arrow curved to the left with the shape of a circle). I do not have any other additional option to choose or buttons to click. I must also say that I do have another hard drive plugged inside the power mac which works fine under the tiger system. It is normally visible and usable while I am working with the system. But after holding C button while restarting computer only one hard drive is visible whose icon appears on the screen. The same situation is while trying to reboot computer from USB stick. It simply doesn't work.

 

Can anyone help me to make my system upgrading possible.
