Restoring Your Unit to Normal Operation
Restoring Your Unit to Normal Operation
Your FTB-1 is set to start using the standard Windows startup sequence.
However, you can also use the emergency system tools feature if you need
to:

check the disk integrity

back up some files directly onto a USB storage device for recovery
purposes

revert your unit to its initial state (as it was when you purchased it) or
restore it with a specific Windows image (WIM) that could have been
provided to you by EXFO customer service, for example.
Note: You may find useful to connect a keyboard and a mouse to your unit before
using the emergency system tools.

The restoration of the system partition cannot be undone or
stopped once it is started.
If you have installed other products that are not included in your
image file, you will have to reinstall them afterwards.
To avoid loosing the data that is stored on the D drive, you may
want to back it up before restoring the system partition. Otherwise,
all your files will be lost.
