They're usually poorly supported by the OEM and many have ditched hybrid graphics in favor of the newer Optimus Drivers.
This link may be of interest to you and contains "updated drivers" however these are unofficial and community supported (meaning you use at your own risk):
Edit: Also boot the installation disk and go into the recovery options and select "Startup Repair" to fix any MBR issues.

And Startup Repair couldn't fix it :/ Is there a way I can boot from a particular partition? There is C and D. Of course the recovery is on D.
If you cannot do any of those three, the partition may have been corrupted.
If you can access the partition through command prompt and the restore image is stored as a .wim file, you can perform an advanced form of recovery by deploying it yourself using the imagex program from the recovery environment:
Thanks for your help anyway Neo

I know this is way after the fact but it sounds like you had a bad OS install. Whenver upgrading operating system software (ESPECIALLY when it involves crappy Vista) make sure you do a CLEAN install. Upgrading from home premium to enterprise or ultimate or something like that you're fine doing an upgrade install but otherwise I always stick to clean installs. Rip your files to an external, wipe the drive partitions and install the new OS, then rip your files back on.
I just try to stick with what originally came on the computer. Its easier that way to me.
