So the system I'm planning on building will have no dvd/bluray cd drives. I will temporarily use an external cd drive to install windows 7 professional 64bit. My question is how do i configure the bios so that the external cd drive boots first. Also after I'm done installing, how do i make sure that the ssd i installed windows onto boots first and that it doesnt try and boot the external cd drive i used to install windows since i will no longer be using it.
