Why has the computer ‘hung’ during reboot?
If, during installation, you have not altered the Boot.ini file to show the current encryption progress then it may appear that the system has hung. The system is fine and Kilgetty is in the process of encrypting the hard drives. This process should take 2-6 hours, but may take longer depending on system configuration. If you wish to show the installation progress, edit Boot.ini before installing Kilgetty, as described in the Kilgetty User Manual.
