I have recently built myself a new gaming computer and I installed Windows 8.1 on it. Today, I wanted to dual boot Ubuntu over Windows. So, the regular, downloaded Ubuntu, got a USB and made it bootable with the "universal usb installer" which i downloaded from some site pendrivelinux. I disabled UEFI Secure boot and fast-boot but it still won't show the boot menu to choose the OS. Anyone help here?
Intel Core i7-4770k not overclocked
8 GB DDR3 CORSAIR VENGEANCE 2x4GB 1600MHZ
SAPPHIRE DUAL-X R9 270X 2GB GDDR5 OC
MSi Z87-GD65 GAMING MOTHERBOARD
CORSAIR AX860W POWER SUPPLY
I think it should run all OS really smooth, but I really don't know how to fix this.
