I am trying to do a clean install of windows 8on my lenovo g500s. I have been using windows 8.1 & now going back to windows 8 but my usb doesnt boot.
It shows in the BIOS menu and i have changed its priority but still it wont boot.
I am using Novicorp Wintoflash software to make a bootable usb and i have used it before...it always worked but now it just wont boot.

I think i am using a corrupted version of 8.1 because it is damn slow....my audio drivers have stopped working and many options wont open in it like windows update, system restore in control panel

A little help would be appreciated.... :)

try updating your bios by looking it up on lenovo support website and enter your computer specs. then up date your drivers, google 'driver booster' and download it which makes it much easier updating drivers
