I disagree with that advice Ralf. I have had a newer kernel just 
installed, to be located far enough into the disk that the bios could 
not reach it to boot it.

Because of that, I have had to redo the default partitioning so as to 
have a separate /boot partition of a bit over 1Gb.

And make sure that when done, before pressing enter, that it is the FIRST 
partition. I have had installers (including ubuntu's) re-arrange the 
partition list on me several times.  Bad dog, no biscuit...
