"MISSING COMPONENTS" error message

If you used the same dvd drive when trying to copy the disk as you did when trying to install, you'd probably get the same results. The idea is to try to eliminate possible causes. Missing components usually means something didn't get copied during the install. Likely causes are jarring the computer at some time when it's trying to read the DVD, a bad install disk, dirt/dust/fingerprints on the DVD. There are other not so likely possibilities, but I'm taking the assumption that you haven't had many problems with your system prior to this. Try it from a different computer. If you don't have one.. see if a friend will do it for you. Not sure what hardware you have, but I'm also assuming it passes the minimum recommended specs.

this remains to be unsolved..

You never did post what kind of hardware you're using.. that's relevant information. For example, certain Dell SATA drivers will cause this error. There are lots people here who know enough to help you solve your problem. Just be patient
