boot only using the sata and install fresh version of windows.
when loading at one stage windows says something about sata drivers and need to hit f6 .
then it askes you to install floppy and it loads this driver.
in saying that the exact same thing happend to me
i tried days to load xp and other windows, sometimes i could format drive other days, i managed to install windows, i even tried 2 different sata ( i normally run raid)
it turned out that the mother board was fauly and got a new one, now its rocking
