Note: If you encounter failures that prevent you from gaining access to the Rescue
and Recovery workspace, you can run the PC-Doctor for Rescue and
Recovery diagnostic program after using a rescue medium to recover the
computer from failures and gaining access to the Rescue and Recovery
workspace. See “Creating and using rescue media” on page 43.
PC-Doctor for DOS
You can also download the latest version of the PC-Doctor for DOS diagnostic
program from:
http://www.lenovo.com/support
The PC-Doctor for DOS diagnostic program runs independently of the Windows
operating system. Use the PC-Doctor for DOS if you are unable to start the
Windows operating system or if the two diagnostic programs preinstalled on your
computer have not been successful in isolating a possible problem. You can run the
PC-Doctor for DOS from a diagnostic disc that you created.

To create a diagnostic disc, do the following:
1. Download a self-starting bootable CD/DVD image (known as an ISO image) of
the diagnostic program from:
http://www.lenovo.com/support
2. Use any CD/DVD burning software to create a diagnostic disc with the ISO
image.
Running the diagnostic program from a diagnostic disc
This section provides instructions on how to run the diagnostic program from a
diagnostic disc that you created.
To run the diagnostic program from a diagnostic disc that you created, do the
