Hi, I just bought a brand new Dell Dimension 5100 computer this week. Anyways upon opening the box and setting it up I noticed the computer didn't come with an OS CD but instead came with a paper that said to go to support.dell.com/pcrt . Well I went to said website and it said to recreate a backup recovery CD to use the one on my computer under Dell Accessories. Well there is nothing under there to create a backup OS CD. I've tried to email Dell and it says my service tag is not valid. I also tried going into chat and it said the same thing.

 

Is there a way I can get a CD for backup of the OS incase I need it? As I've had to reformat my old dell a couple times.  And any clue on why my service tag is not valid?

 

 

Thanks.
