• Follow these steps: 
 
1. Disconnect the encrypted drive. 
2. Connect an unencrypted drive with an installed operating system (or install it on the 
drive). 
3. Upgrade the BIOS. 
4. If it does not help, please report this bug to the manufacturer or vendor of the computer. 
OR 
• If the BIOS/motherboard/computer manufacturer/vendor does not provide any updates that 
resolve the issue and you use Windows 7 or later and there is an extra boot partition 
(whose size is less than 1 GB) on the drive, you can try reinstalling Windows without this 
extra boot partition (to work around a bug in the BIOS). For information how to do so, see:

One of the following problems occurs: 
 
• After the pre-boot authentication password is entered during the system encryption pretest, 
the computer hangs (after the message ‘Booting...’ is displayed). 
• When the system partition/drive is encrypted (partially or fully) and the system is restarted 
for the first time since the process of encryption of the system partition/drive started, the 
computer hangs after you enter the pre-boot authentication password (after the message 
‘Booting...’ is displayed). 
• After the hidden operating system is cloned and the password for it entered, the computer 
hangs (after the message ‘Booting...’ is displayed).
