I believe I only have 2 drives, not including the hard drive Drive C, I have a dvd drive which was drive D and the new dvd rw drive which was drive E that i am using to replace a cd rw drive that was broken, I thought that since I wasn't making any additions that the cables would be connected as they were previously.
Could the problem possibly be on the set up page where the booting sequence is posted, if the first drive (drive #1) it tries to boot is not there, it prohibits the other drives from being detected? Maybe I should change some things on my setup?
