Don't click the driver tab first of all. Unless your installing a RAID or special PCI card.
In other words, for a regular Windows 7 install, the driver button is superfluous. Disregard it and continue on with your install and from there you should be good to go.
Here's what I'm talking about
:
You're making this more complicated that it really is. With a notebook computer there is no reason to use that "Load Driver" feature at all.
No need to partition your notebook's drive either, unless you want to. Windows 7 will automatically format it and install with no further assistance on your part.
Keep us posted.
