Could someone pls guide me how can I burn out the recovery image from the hidden partation (5.13 GB) to the external DVD-ROM so that I can extend my harddisk for more space? And, pls guide me how I can delete that partation and conbine with my existing partation. Currently I have only one partation which is "C" drive.
Well, I can't give you an extensive step by step guide here, but instead I can hopefully give you some hints and pointers into the right direction.
Usually a Thinkpad comes along with some ThinkVantage software named Rescue and Recovery, which is Lenovos own imaging software and which allows to perform and restore harddisk image backups. Informations about "Rescue and Recovery" software (downloads, user manuals etc.) can also be found on the Lenovo webserver under the ThinkVantage sections. You will also find a lot of information related to this theme if you search through the Thinkpads forum --> here.
As an maybe much easier to use alternative, you should take also a look onto Acronis TrueImage, which is a very good and easy to use imaging software. With the help of Acronis TrueImage you can easily back up the recovery image from your hidden partation onto another harddisk, CDs or DVDs, so that you afterwards (...after verifying that your image backup really works and also can be restored) can delete/destroy/recombine the backup partition with some appropriate tool like Acronis Director or Partitition Magic etc.
Take a look on the websites of the above mentioned software tools, there you should also find user manuals and maybe some tutorials for how to use those tools. You can also do some specific Google search for this theme and then look, if there is maybe some good step to step advice among the hits the search querry returns.
