Download this file, it even has links in the pdf to guide you through it... If you cann't achieve it this way, than I'm sorry... You're not (yet) ready to flash anything and please do some more reading...
First tip if you want to hack/flash anything I suggest you put yourself a desktop pc together. For reflashing the drive you best use the via motherboard.
Laptop's are nearly impossible to use when it comes at interfacing with devices...
It's just a tip, probably there are people using laptops but I won't ever use them for hardware hacking or flashing :p
ps: Gazcoigne your sentence was a little bit strange, but I understood it
