Drive encryption (winmagic)

Hello,

 

Welcome to the HP Support forum.

 

I am sorry for the issues you are facing.

 

You are correct - this is called preboot authentication and once the password or other authentication token is entered (and if it is correct), the operating system should begin loading.

 

Is the password accepted ? If not, are you sure it is correct ? If it is accepted and you seem to go to the next screen - this means there is an operating system problem - e.g. Windows cannot start correctly. In this case, if drive encryption is activated with PBA, there is not much that can be done other than you performing HP Recovery (reimage) to restore the PC to factory default condition.

If this is the case and if your PC originally came with Windows preinstalled, this is what needs to be done:

Drive encryption (winmagic)

Once the Hard drive is locked for preboot security, the information is written on PUID area of the drive which is impossible to remove from hard drive unless OPAL Erase utility is used.

I have same problem, and I have tried followng.

1. Put hard drive in another laptop: The security prompt still comes up so its not BIOS issue, its PIUD on the disk

2. Reinstall Windows, reinstall HP Client security and turn off boot device protection

3. Remove encryption on the drive

 

There is no way I can remove the boot device protection. I have asked HP engineer to give me OPAL Erase but for some reason they are not willing to provide it.
