Im very new with this linux systems and have a first problem already... but I fix it just now with good luck
I struggle with this problem couple a days and installing many times operating system and try and try....
Problem was solved when I change in BIOS settings -> IDE DMA TRANSFER ACCESS - "ENABLED"
if that setting is in "DISABLED" position, I get allways "savedefault" message and debian etch (Ubuntu)* never load and work at all..
Motherboard is Commell LV-672 and with Celeron D*processor.
