Are you running RAID? To me it looks like it is looking for either the RAID or SATA controller for your motherboard so it can access the drive.
A bit more information on your system as well will help.

You are missing a driver for either a raid (not likely cause its a laptop) or the HD. Did you get a cd with the computer that had dirvers on it? what OS was on it when you got it?

You won't need to worry about a RAID driver on your laptop.
Like zigzag noted, you are most likely missing a driver for your hard drive or hard drive controller. The Vista ones on the CD will most likely work to get you going.
If you were to copy them to a USB drive you could browse for them when you get to this point again and install them.
