Recently upgraded to Win 7 64 bit from Xp, then happened to notice my BIOS is a few versions out of date, so I tried to download it but noticed that Win 7 is not an option under OS. So I took the Vista version, thinking its the latest on there but it won't install, not a major problem as I will just stay with current version but just wondered if anyone else has come across anything like this and if so what version OS did you try ?
