Easily Remove OEM Partition by Using AOMEI Partition Assista

What is OEM Partition?

When you buy a brand computer, such as Lenovo, Dell, HP...rather than a DIY one. The Original Equipment Manufacturers (OEMs) will contain a system recovery partition on the computer hard drive. This partition usually includes a digital copy of the Windows installation file in case of emergencies.

(Figure 1)

The special partition, normally hidden, can have a size of from few MB to 10 GB or more. Generally speaking, OEM partition is not very useful to us. If we reinstall the operating system in future, the OEM partition is more useless. So we said the OEM partition can completely be removed if you are not a computer newbie. However, in some OEM system, such as those from IBM/Lenovo, is impossible to delete within Windows.

How to Remove OEM Partition?

Now we concern how to remove OEM partition.

The first method:

By using advanced Diskpart, a text-mode command line tool interpreter which enables storage objects such as disks, partitions or volumes configuration and management from a script, remote session, or direct input from a command prompt. (free download for XP, 2000, and 2003).

Steps:

  • 1.Open a command prompt as administrator.
  • 2.Run Diskpart application by typing Diskpart in the command prompt.
  • 3.Type “list disk”. This will show all the disks.

We know from the Figure 1 that the OEM partition is located on Disk 2.

So we type “select disk 2” and press Enter key.

Type “list partition” to list all the partitions on the disk.

Now we can see the OEM partition is Partition 1. So type the command “select partition 1”.

 

Then type “delete partition override” and press Enter key.

Thus, we have removed the OEM partition successfully.
