Don't know whether this post ended up in the right category... Nevertheless:
Until recently I had a system with two HDDs, XP installed on one of them and the second one for data storage. Everything working fine...
I then bought a third HDD, unplugged the SATA connector from the XP disk, installed Win7 on the new disk and were perfectly happy with the way it worked.
However, the mystery starts when I hook up all three drives, having the OS drives on SATA 1 and 2, respectively. It turns out that regardless of how I set the (HDD) boot order in BIOS, it's always XP that boots.
I've heard many theories about what might be the problem (all from people that were unfamiliar with the problem at hand) - ranging from the MB's inability to actually use the BIOS settings, to the MBR on the Win7 accidentally and implicitly pointing to the XP drive, via SATA port configuration issues (e.g. it would matter in what SATA ports I plug things in...).
What are your ideas in this matter? Has anyone experienced similar things?
