I have written a number of times recently about UEFI Boot, and how much trouble I have had getting it set up and getting it to stay the way I want it.
It is important to remember that system manufacturers sometimes make BIOS firmware updates available, and installing such updates can sometimes be of significant help with existing problems.
An example is my Acer Aspire One 725. I have installed several different Linux distributions on it (openSuSE, Fedora, Ubuntu and Debian), and I had run into two related problems.
