partitioning - How to create Restoration Partion?

For some time now, when buying new computers (laptops in particular) from big name brands-like DELL, HP, TOSHIBA, etc.-most of them come with a "rescue" or "restore" partion instead of installation CD/DVD. Said partitions have everything needed to rebuild the factory installed OS, unfortunately they also include all crapware that the OEM installed on the machine.
Is it there a way to custom create such a partition with out all the useless software included?. They seem quite appealing considering they only use about 10GB-20GB of space and offer the pretty much the same functionality as a complete system image/backup.
