Recover from a failed Linux boot
If your Linux computer fails to boot after a kernel upgrade, disk swap, or other system change, you're not helpless. The Grand Unified Bootloader (GRUB) gives you ways to control the boot process and recover. Or, if necessary, emergency boot disks that you create with an external tool can come to the rescue. Learn procedures and GRUB commands that can help you boot in problem situations, and find out about a life-saving external tool for BIOS-based systems.

Make the most of large drives with GPT and Linux
Once a remote prospect, an important barrier in disk storage has become a reality: the venerable master boot record (MBR) partitioning scheme can't fully handle disks larger than 2.2TB (2TiB). With disks as large as 3TB readily available and with much larger RAID arrays common, alternatives to the MBR partitioning scheme have become important to understand. The heir apparent is the GUID Partition Table (GPT). Learn how to make sure your Linux system is fully prepared for the future of disk storage.

Enable multiuser logins with VNC
Virtual Network Computing (VNC) is a popular tool for providing remote access to computers. The usual VNC configuration is optimized for single-user workstations, and logging in to the VNC port directly accesses a single user's desktop. This configuration is awkward on multiuser computers, however. Fortunately, you have an alternative. By linking VNC to a Linux computer's normal X Display Manager Control Protocol (XDMCP) server, accessing the VNC port enables users to provide their user names and passwords, thereby enabling a single VNC server instance to handle multiple user logins.
