I am planning on building a new computer, and I have ordered all of the parts. The motherboard is an ASUS p8z77-v le. I am wondering if I will be able to install the OS from a USB or if the motherboard will not have the drivers installed so it will not work. My friend just finished building his first computer and he used the ASUS p8z77-v lk, and it did not come with any drivers installed so he couldn't install the OS with a USB. I am wondering if I will have to spend another 20 dollars to get an optical drive or if the motherboard I am getting will have some basic drivers so that I can at least install the OS.
