WARNING: By restoring key data using a TrueCrypt Rescue Disk, you also restore the 
password that was valid when the TrueCrypt Rescue Disk was created. Therefore, 
whenever you change the password, you should destroy your TrueCrypt Rescue Disk and 
create a new one (select 
System
-> 
Create Rescue Disk
). Otherwise, if an attacker knows 
your old password (for example, captured by a keystroke logger) and if he then finds your 
old TrueCrypt Rescue Disk, he could use it to restore the key data (the master key 
encrypted with the old password) and thus decrypt your system partition/drive.

If 
Windows is damaged and cannot start
, the TrueCrypt Rescue Disk allows you to 
permanently decrypt the partition/drive before Windows starts. In the Rescue Disk screen, 
select 
Repair Options
> 
Permanently decrypt system partition/drive
. Enter the correct 
password and wait until decryption is complete. Then you can e.g. boot your MS Windows 
setup CD/DVD to repair your Windows installation. Note that this feature cannot be used to 
decrypt a hidden volume within which a hidden operating system resides (see the section 
Hidden Operating System
). 
Note: Alternatively, if Windows is damaged (cannot start) and you need to repair it (or 
access files on it), you can avoid decrypting the system partition/drive by following these 
steps: If you have multiple operating systems installed on your computer, boot the one that 
does not require pre-boot authentication. If you do not have multiple operating systems 
installed on your computer, you can boot a WinPE or BartPE CD/DVD or you can connect 
your system drive as a secondary or external drive to another computer and then boot the 
operating system installed on the computer. After you boot a system, run TrueCrypt, click 
Select Device
, select the affected system partition, click 
OK
, select 
System
> 
Mount 
Without Pre-Boot Authentication
, enter your pre-boot-authentication password and click 
OK
. The partition will be mounted as a regular TrueCrypt volume (data will be on-the-fly 
decrypted/encrypted in RAM on access, as usual).
