Since you have a new Thinkpad.
All new TP's that come with an os installed and a coa sticker on the bottom also have a hidden partition on the hrive. If you hit the Blue Access IBM button upon booting you will be given options to restore your os to factory. BTW this works amazingly well.
You can also download a prog from the IBM website called Restore and Recover. With this you can follow the prompts and make your own recovery cds. Should be around 8 of them depending on the software options that came with the Thinkpad.
You can order a set of cd's from IBM for around $40.00.
You can copy the i386 folder from your current installation to cd, and clear your hdrive, copy it back to hdrive and do a reinstall from it. You will need to use the coa# from the bottom of the TP to activate. If you do the Access IBM method, no activation is necessary.
The last option is to use another oem cd and usually the coa# works.
Unless you are very limited on hdrive space, there is no reason to delete this hidden pre-service partition from your TP. There is an option in bios to make it viewable if you want to image the drive with an imaging program. If you buy a 2nd hdrive bay adapter from IBM for $45.00 and free shipping, you also get an imaging prog called EZgig which is identical to Acronis Trueimage, but works a lot more reliably. A bargain for that price.
