+
+Converts a disk from MBR to GPT partitioning without modifying or deleting data on the disk.
+
+MBR2GPT.exe /validate|convert [/disk:<diskNumber>] [/logs:<logDirectory>] [/map:<source>=<destination>] [/allowFullOS]
+
+Where:
+
+ /validate
+         - Validates that the selected disk can be converted
+           without performing the actual conversion.
+
+ /convert
+         - Validates that the selected disk can be converted
+           and performs the actual conversion.
+
+ /disk:<diskNumber>
+         - Specifies the disk number of the disk to be processed.
+           If not specified, the system disk is processed.
+
+ /logs:<logDirectory>
+         - Specifies the directory for logging. By default logs
+           are created in the %windir% directory.
+
+ /map:<source>=<destination>
+         - Specifies the GPT partition type to be used for a
+           given MBR partition type not recognized by Windows.
+           Multiple /map switches are allowed.
+
+ /allowFullOS
+         - Allows the tool to be used from the full Windows
+           environment. By default, this tool can only be used
+           from the Windows Preinstallation Environment.
