After installing Ubuntu Desktop (latest version) onto my iMac (latest version) via CD and following its instruction to remove the CD and to reboot my machine won't boot. It gives me a blinking underscore at the top left hand side of my screen.
I'm in the "Try Ubuntu" phase, working with this... https://help.ubuntu.com/community/BootPartition
I'm eager to have my workstation functional again. I looked around here and on the web all of today with not much luck; my guess is that I have improperly set up the boot partition. I chose to remove everything during the install process in the hopes that I would be able to have a fresh machine. I'm a novice but would love to learn and appreciate any help that anyone's able to give.
