I was recently deploying Windows 7 on an older PC(not too old) and in the upgrade proccess it said setup could not continue and rolled back my upgrade. I suspect that it is because of the raid, because it stopped in the middle of the expanding files stage. The driver
version on there is 18.104.22.168, which I believe is the most recent for vista, so can I rule this out as a reason. Theres 50GB free for upgrade.
