Ubuntu 12.04 cd install

[MrJimG]

I have Ubuntu 12.04 installed on my Dell optiplex GX240 and it works great but I can't seem to get it working on another Dell Dimension 8200, it installs fine but when it reboots there is no boot choice. I tried burning a new cd at a slower speed but when I reinstalled I have the same problem, no choice on boot up. I am new to Ubuntu so any suggestions would be appreciated.

Did you check the cd in live mode before installation?? and did u check for drive errors too?
maybe graphics driver may cause a problem too... there maybe other reasons too for not restarting to your ubuntu....
