Windows 7 Drivers Required... WTF???!!!

You can also check if your bios lets you change the SATA config from AHCI to IDE/ATA. If it does, change it, press F10 to save and exit, then try installing win7.

@>Theog, i checked my disks, it came up with a message saying no errors
@>Bill2, Thank you for your reply, i will try that as soon as i start my laptop... this may take some time

Update, i launch the file, and instead of going through setup, straight away, it says could not find driver info

What step do you get to in this tutorial?

SATA Driver - Load in Windows 7 or Vista Setup

Also you should deep clean your HD to get the cleanest possible slate for reinstall, in case you were infected or have a hidden partition interfering with reinstall:

Boot Windows 7 DVD Repair console or Repair CD, open a Command Line, type:
DISKPART
LIST DISK
SELECT DISK # (for Windows 7 disk)
clean all (applies zeros, deepest clean, takes about an hour per 320gb)
create partition primary
select partition 1
assign letter=c:
active
format
exit

Now try booted Custom install to partition you have just created, with all other HD's and USB devices unplugged.
