UEFI, Secure Boot, Windows 8 and Ubuntu 14.04 - more learnings

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.

Ralink-based wifi access point in Linux - frequent dropouts on Windows clients

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.

notes on installing grub on a disk that is not mounted as root

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.
