Hello DutchieP, welcome to NBR. As I am sure you already gathered, F4 won't boot Recovery if your Recovery partitions are gone. And as go45cvi indicated, the only way to get them back would be if you had a bootable Factory Image backup on a USB stick from your own or exactly the same model as yours. Of course you can backup your current Windows installation and use that as baseline, but if you want a fresh start, you need Win8 install media. Samsung doesn't provide those for Win8 PCs and Microsoft isn't making them publicly available. The links below are some posts that cover various legal sources of ISOs downloads. We don't discuss "alternative" sources on the forum. http://forum.notebookreview.com/sam...y-bridge-np900x3e-np900x3f-3.html#post9323404 http://forum.notebookreview.com/samsung/706510-samsung-laptops-bricked-using-uefi-9.html#post9287299 http://forum.notebookreview.com/sam...780z5e-np870z5e-np880z5e-205.html#post9312619 I think, as go45cvi said, you should try to obtain proper Win8 install media from the seller. You bought a laptop which includes a Win8 license, and he/she wiped the installation source that came with it (the Recovery partitions).
