Problem installing Mac OS X Lion on Mac Mini I am installing Mac OS X Lion on a Mac Mini (c2d, 2GB RAM). The installation goes fine, until it rebooted. After rebooting, it shows the following screen for almost 3 hours. The  progress bar does not indicate any remaining time. 

Should I continue this or cancel the setup?
If you don't have anything important on the box. I would reboot into Recovery Mode try installing Lion again.

If that fails then erase the hard-drive (back up any stuff you need to), and try to install Lion again on a clean drive. It should not hang for 3 hours plus on the install.
