Insert the USB ,power up and keep tapping f8 to go to boot menu and select USB Drive ?
I just finished building a PC the only part left is the operating system. I pluged everything in and when I turn on the monitor it flashes to some weird menu looking screen then to a screen that says: Reboot and select proper boot device or insert boot media in selected boot device and press a key. Not my uncle just gave me a usb key which he says has windows 10 on it and that he used it for his laptop and it worked. When I plug it in nothing different happens differently than before. Please help. I cant get into the BIOS, no matter what i press it doesn't work, ive tried other methods as well none work it always doest he same thing then switches to the reboot and select blah blah. Please help me!
