Hi I have installed a DVD player burner in my sons computer but when we try to boot up it comes up insert Diskette,I thought maybe it is the jumper on the DVD player moved it to all positions still no joy.If I take the DVD player out the computer boots up and starts fine.I tried changing the boot order as well still wont start up.I only know a small amount of knowledge of computers so any ideas to fix this problem.Regards Martin.
