We got a brand new server Hp Proliant Gen 9 server. We wiped the logical arrays and started from scratch. So far, I've managed to install Windows 2012 R2. But I can see there are a load of drivers missing. I've downloaded them from the HP by using the serial number of the machine on the site, however everything I download doesn't get rid of the question marks (in the photo) in device manager.
Do I have to download some sort of bootable cd/dvd drive which installs of the drives from boot, rather than from the actual Windows menu?
