Its like something is mounting it daring boot or > something and isnt releasing. > Can you describe the steps one by one that you take from the point that you boot into the system to the point that you put in the cd in the cd drive and try out the burn or mount command? Make sure you post the exact messages that you get when you try things out and the exact commands that you try out. Also make sure to report any cd related activity for example, does a window pop-up when you insert the cd in the cd drive? Remember the more relevant information you give, the faster your problem will be solved!
