We finally retired the 12.04 team server, and moved to a new 14.04 server
One of the team servers, which was set up with a RAID1 array had a disk that went bad. Here's a rough outline of how that was fixed.
This posting is a summary of how I got two systems to dual boot windows 8 and Ubuntu 14.04. Note that this was done on systems that didn't boot legacy, and had secure boot enabled.
One of my recent projects was built around an Intel Atom system. One of its functions was to be a wireless access point. The chip that was in use was an Ralink 8192, hooked up through a USB port. A lot of clients (Windows, Android, iPhone) either dropped the connection frequently, or wouldn't connect at all.
This block describes a remedy.
During install fests we sometimes need to install grub on a disk that is currently not mounted on root. For example, if a system can't be booted from its hard drive, but can be booted from a live usb, we want to boot from the live usb and "repair" the hard drive by installing grub on the hard drive. Once the hard drive is "repaired," the system can be booted again from the hard drive.
The attached word doc shows a walk through of how to add a USB printer to the list of available printers in Lubuntu 13.10.
Hope it helps.
