I'm sorry you said that.
I have a list of links for recovery instructions of several OEMs and
http://support.vaio.sony.co.uk/tutor...voe_en_GB_cons
used to be a good one, freely accessible.
Unfortunately Sony have redirected the link to a generic site, where information is completely inaccessible to non-owners, so I can't even find what the boot-time hot key is for accessing the recovery partition.
You'll need to trawl around yourself.
Incidentally your model number was unrecognized, possibly because it's the European hub, and that model isn't available here. I also tried the US site (which didn't wan't to let me in because of my UK IP), but the model number was unknown there too.
You'll need to start in your own country site and take it from there.
