How big are OEM partitions on the computer? Until your computer has failed then your OEM partition is “useless”. If you have little experience in reinstalling the OS, an OEM partition can be a great solution for you. You can use it in case of any system failure in the computer without using the OS installation disk. If your PC/laptop has an OEM partition, it means you are using a device from HP, Dell or Lenovo.Īlternatively, an OEM partition is called the factory default recovery section.
