Deleting the Recovery Partition is NOT RECOMMENDED
I personally DO NOT RECOMMEND using this METHOD above, as of the ERRORS you may receive below with the Microsoft Recovery USB Drive.
I would recommend you making the OEM manufacturer's Recovery DVD's or USB drive.
You can order the Microsoft official OEM Recovery disks from the OEM manufacturer's website. Essentio Recovery Software
The Recovery USB drive & Recovery Partition can be very problematic, I recommend you also make a Windows System Image.
You owner's manual should have the procedures for recovering a system back to factory condition. The newer devices seem to be using the Windows 8 Reset option which uses an image normally kept in a Recovery partition. Using that image to reinstall will take the system back to a factory state.
When you make a Recovery Drive, the link Theog gave you, it will copy that image to the flash drive if there is one. If your system uses a special OEM procedure for recovering, you need to follow those and use their recovery media or some media made with some special OEM utility.
