why cant i get onto internet and install drivers because no drivers for ethernet or network controller?

It aint that its not letting you- its that it dont know how to cos you deleted the drivers when you re-installed

Get a friend to go to the HP website and download ALL the drivers for your pc from there (should be in the support page)

(If they aint there then try contacting HP online support via your friend , tell them whats happened and if they can supply the drivers

When you get them then copy to a flash drve and copy them onto yoru pc then install them ALL

The only problem you have is that you did not think about what you were doing before you did it.
You SHOULD have made sure you had ALL the drivers for your pc before you re-installed.
(its likely there will be several drivers for your pc and its important you install them ALL)
