Q. How can I add a boot option for the new Diagnostics and Recovery Toolkit (DaRT) to my machine?

A. Once you've created your DaRT media, you can copy the content to your system drive (such as to C:dart), and then add a boot entry. Below are the commands I used. Note that the fourth command returns a GUID, which you need to use in the subsequent commands.

C:Usersjohn>bcdedit /create {ramdiskoptions} /d "DaRT Tools"
The entry {ramdiskoptions} was successfully created.

C:Usersjohn>bcdedit /set {ramdiskoptions} ramdisksdidevice partition=C:
The operation completed successfully.

C:Usersjohn>bcdedit /set {ramdiskoptions} ramdisksdipath Dartbootboot.sdi
The operation completed successfully.

C:Usersjohn>bcdedit /create /d "DaRT Tools" /application OSLOADER
The entry {4b1d6c3c-e2b9-11df-813f-9b8d94709596} was successfully created.

C:Usersjohn>bcdedit /set {4b1d6c3c-e2b9-11df-813f-9b8d94709596} device ramdisk=[c:]Dartsourcesboot.wim,{ramdiskoptions}
