I had Ubuntu running on an acer easyStore box. When the power supply got too loud, I decided to move the harddrive to a desktop box. However, when I tried to boot up, the screen tells me to pick a cd drive (even though I set hard drive as the first option in the boot order in the bios settings). I luckily have an Ubuntu cd so I was able to boot into that. One of the options there is to boot from hard disk and that works fine. So how do I get machine to boot from the hard disk?
Potentially useful pieces of info: The desktop was purchased around 2007. The easy store was purchased in 2011. I suspect an issue with the partition table format (MBR vs GPT) but don't know for sure if that's the problem.
Here is the output of gdisk and parted:
