@ -96,11 +96,11 @@ MBR2GPT: Validation completed successfully
In the following example:
1. Using DiskPart, the current disk partition layout is displayed prior to conversion - three partitions are present on the MBR disk (disk 0): a system reserved partition, a Windows partition, and a recovery partition. A DVD-ROM is also present as volume 0.
2. The OS volume is selected, partitions are listed, and partition details are displayed for the OS partition. The [MBR partition type](https://msdn.microsoft.com/library/windows/desktop/aa363990.aspx) is **07** corresponding to the installable file system (IFS) type.
2. The OS volume is selected, partitions are listed, and partition details are displayed for the OS partition. The [MBR partition type](/windows/win32/fileio/disk-partition-types) is **07** corresponding to the installable file system (IFS) type.
2. The MBR2GPT tool is used to convert disk 0.
3. The DiskPart tool displays that disk 0 is now using the GPT format.
4. The new disk layout is displayed - four partitions are present on the GPT disk: three are identical to the previous partitions and one is the new EFI system partition (volume 3).
5. The OS volume is selected again, and detail displays that it has been converted to the [GPT partition type](https://msdn.microsoft.com/library/windows/desktop/aa365449.aspx) of **ebd0a0a2-b9e5-4433-87c0-68b6b72699c7** corresponding to the **PARTITION_BASIC_DATA_GUID** type.
5. The OS volume is selected again, and detail displays that it has been converted to the [GPT partition type](/windows/win32/api/winioctl/ns-winioctl-partition_information_gpt) of **ebd0a0a2-b9e5-4433-87c0-68b6b72699c7** corresponding to the **PARTITION_BASIC_DATA_GUID** type.
>As noted in the output from the MBR2GPT tool, you must make changes to the computer firmware so that the new EFI system partition will boot properly.

To fix this issue, mount the Windows PE image (WIM), copy the missing file from the [Windows 10, version 1903 Assessment and Development Kit (ADK)](https://go.microsoft.com/fwlink/?linkid=2086042) source, and then commit the changes to the WIM. To do this, follow these steps:
1. Mount the Windows PE WIM to a path (for example, C:\WinPE_Mount). For more information about how to mount WIM files, see [Mount an image](https://docs.microsoft.com/windows-hardware/manufacture/desktop/mount-and-modify-a-windows-image-using-dism#mount-an-image).
