Hey Flanker
Well the situation was as follows....
My two mates were doing the build. The guy we built for was inexperienced with pcs while the other guy present is pretty handy. I was not there when they assembled the machine as I was at work. When I heard they had problems I decided to post on here. I was told by the inexperienced guy on msn that they were having problems booting disks and was informed that it may be a hard drive problem. That was misinformation though as when I spoke to the other guy doing the build he said that he thought it was the dvd drive that did not work and he was proved right.
Now I went down the following day to see the assembled pc, put in my dvd drive and booted up the system. It all worked, windows installed, no drivers required. My mate who was doing the build later explained to me that sata HDDs do not need drivers. What he said was- windows uses the drivers, but if windows will not boot then what use are drivers. In other words drivers need windows and windows was not installed.
With that said I fail to see how drivers are required at all. The poster dark sniper said he built a machine with sata hdd and used drivers... I don't doubt that was the case but I too am no closer to seeing why or how you might need a driver to install sata drives. Perhaps drivers are required to install a second drive, i don't know
So in short the dvd drive was the problem and we booted up windows, no drivers necessary.
I am just relaying what my friend told me here but saying as you asked I tried my best to explain his logic
