sorry but that made no sense... but what i think your saying is that you cant get to the windows setup screen?

also maybe it just needs to boot off your usb

also what is your main(born with) language? because if it is not english sorry for being kinda of mean i just dont understand what you are saying

I just got a new Toshiba Satellite C850 b561 with Windows 8 pre-installed. I got my Windows 8 pro 64-bit installation on a bootable USB (it works with all of my other computers, including my Satellite . As I hate Windows 8 I decided to make a clean install with Windows 8 pro & configuration my hard disk . I created a bottable USB, plugged it in, went into the BIOS and changed the boot priority to USB as primary but-.. When I saved it doesn't boot from the USB. It just boots right back into Windows.

I have tried the same thing with a Windows 8 pro DVD. It gives me the following message when I try to boot from any of the above: "System doesn't have any CD/DVD boot option." and "System doesn't have any USB boot option."

What should I do? I'm in a hurry with this laptop as I'm using it in university.

have you tried going into the boot menu? you dont change it through the bios it has to be through the boot menu

do you already have windows installed or any OS installed on your laptop?

 

[nessim228]
