I just finished building my new pc. the specs are below. So when i bought all the parts i overlooked the fact that i didn't buy a case with space to put a disk drive. i bought the disk drive for the sole purpose of installing windows 8.1 from disk. I assumed that I could just hook up the disk drive and then after i install windows, disconnect the disk drive and set the boot priorities to boot from the HDD but when i do that i get the error 99 code on the bottom right corner. when i leave the disk drive hooked up however it will boot into windows normally. what do i do?
