I get the same errors, it is probably because I selected to install vista from win xp and then when it rebooted into setup it could not find the Hard drive because its on a RAID controller (Promise FastTrakS150TX2Plus) Anyway when booting from the DVD you have an option in the setup part to load the drivers for your RAID/SATA controller but If I insert my floppy it does not detect the drivers from the floppy. I have just read that many people have trouble installing Vista on RAID/SATA hdd's.
