I'm not very familiar with MSI boards/BIOS but if you've not tried already.. try setting your HDD's mode in BIOS to AHCI if your not raiding the drive/drives. Then try installing the OS. This allows SATA drives to use hot swapping & Native Command Queing etc if the drive supports it. I've had trouble myself for some reason installing Vista on a couple of drives that have had the IDE/AHCI/RAID not chosen correctly.
