Parameters

-DataSourceID (required): Specifies the data source ID. Use Get-WIMBootEntry to display the data source ID.
-ImagePath (required): Specifies the full path to the renamed or moved image file.
-LogLevel: Specifies the maximum output level shown in the logs. The default log level is 3. The accepted values are as follows: - 1 = Errors only - 2 = Errors and warnings - 3 = Errors, warnings, and information - 4 = All of the information listed previously, plus debug output
-LogPath: Specifies the full path and file name to log to. If not set, the default is %WINDIR%\Logs\Dism\dism.log. In Windows PE, the default directory is the RAMDISK scratch space which can be as low as 32 MB. The log file will automatically be archived. The archived log file will be saved with .bak appended to the file name and a new log file will be generated. Each time the log file is archived the .bak file will be overwritten. When using a network share that is not joined to a domain, use the net use command together with domain credentials to set access permissions before you set the log path for the DISM log.
-Path (required): Specifies the path to the disk volume of the WIMBoot configuration.
-ScratchDirectory: Specifies a temporary directory that will be used when extracting files for use during servicing. The directory must exist locally. If not specified, the \Windows\%Temp% directory will be used, with a subdirectory name of a randomly generated hexadecimal value for each run of DISM. Items in the scratch directory are deleted after each operation. You should not use a network share location as a scratch directory to expand a package (.cab or .msu file) for installation. The directory used for extracting files for temporary usage during servicing should be a local directory.

Prerequisites
