If you've been running Linux long enough to have upgraded your system more than once, you probably have several Linux kernels lurking around your system. If you discover that a certain application no longer works for you, you can go back to a previous kernel to try to run your program. GRUB, the boot loader found in most Linux distributions, lets you choose among operating systems and kernels installed on your box. Many people, however, fear that messing with GRUB may ruin their system, because of its many esoteric options, and configuration file text that often contains no help comments. QGRUBEditor can help you view and edit the GRUB boot loader from a graphical user interface.

The two types of user accounts are Administrator and Standard. The user account created during the installation process is, by default, of the Administrator type. That is the superuser. A user with that account can perform any task on the system.
