  1. Hello and welcome to the forums
    Check the cable connections, and make sure they are plugged in properly, if it didn't help,try using different cables.
  2. Thanks Maziar! I've checked the cable and connections all are plugged properly. I've also checked it by replacing cables. Though I am not expert of computer, is there any possibility with bios which does not retain hard disk and cd-rom entries in bios.may be its need to be updated in current version. but I don't know how to do it if this is the case.please help me out!
