BSD

If you have a disc image file in the ISO file format, you need to burn or mount that disc image before you can start using the contained data. If you are using the FreeBSD Unix operating system, then, like many other operations, you must mount the ISO from the command line. You mount the drive by creating a hypothetical drive and then mounting the ISO data to that drive.

PC-BSD is a free, open source operating system that is a customized version of the FreeBSD operating system, with installers and software designed for normal desktop use. PC-BSD receives normal security patches through its update program, but the program can't upgrade to a new operating system release. When a new version of PC-BSD is released, you can download the new installer and perform an upgrade install, which keeps your existing settings, home folder files, user accounts and installed programs.

Worse yet, that blue screen is generally followed by an immediate reboot, meaning that the computer user will not even have time to read the message fully. This problem can be remedied with a few easy steps.
