Hello @G_A7

Welcome to the HP Support forum. Thank you for posting.

Is this PC your personal one or company owned asset ? McAfee Drive Encryption is a software typically found on the PCs of business computers, corporations.  If this is your work PC, please contact your company's IT support team and your local HelpDesk.

Any McAfee "fatal" error cannot be fixed remotely and requires onsite assistance.  If the error you post is correct, this is what it is

0xEE0E0001

Authentication User Interface definition file failed

The issue you now have is probably caused because McAfee's PreBoot File System (PBFS) got corrupted. PBFS is stored on the HDD's Master Boot Record (MBR). This happens often with McAfee.

Some general tips you need to follow with regards to McAfee DE and Windows:

- Windows 10 needs to be deployed with Secure Boot OFF and Legacy mode ON - settings in the BIOS

- Ensure BIOS is updated to the latest version and check the above settings

Ensure McAfee DE is the latest version installed.

You need to contact your security administrator(s) and work with them to perform Emergency Boot > https://kc.mcafee.com/corporate/index?page=content&id=KB71868

Emergency boot is performed using XML file from the McAfee's ePO console and using DETech disc.

Emergency boot basically places Windows MBR, boots to Windows desktop. McAfee Agent communicates with the ePO, notifies the ePO about the Windows MBR , not McAfee MBR and eventually replaces and repairs the boot data/PBFS/MBR

If Emergency boot does not work, PC needs to be reimaged.

For further steps, get in touch with the company's security admins, disable McAfee PBA screen or get in touch with McAfee Technical support > https://support.mcafee.com/ServicePortal/faces/wcnav_defaultSelection?_afrLoop=1571452459502000&_afr...

If your company policy requires PBA screen (preboot authentication) but McAfee PBA is set to disabled by policy, you can enable BIOS start up password for enhanced security.

Hope this answers your queries. Provide your feedback/update.

Hi,

The error message I am getting is: Failed o display error message box.

Fatal error 0xEE0E0001.

It is business computer, you are right. Local IT/IT support Team could not help. They tried decrypt it, but i have been informed that there is no enough space on the computer. There are very important files in it, so i am trying my best to be able to extract them.

I will contact to McAfee support and see what they say.

Thank you for your feedback

Hi @G_A7

If decryption process has started but has failed somewhere in the middle during the decryption process, chances for successful data extraction is so low, minimal, pretty much zero. If the process has been stopped, interrupted, data is semi-encrypted, semi-decrypted and process needs to be started at same point where it stopped and this is the most difficult part.

If decryption hasn't been attempted yet, do not try it but first boot the computer using DETech tool (WinPE or A43), unlock the storage drive (HDD or SSD) using McAfee DETech tool and try to browse the storage drive to see if you will be able to browse the files (WinPE/CMD/A43)

Please, note that any encryption software (like McAfee) is there for data protection and McAfee does not guarantee successful data recovery. It is always recommended that you back-up your most important files and store them somewhere else (don't store them only in your HDD).

The 3 security principles (CIA) include: confidentiality, integrity and availability

You have come to a over-protective environment and data is no longer available/accessible, therefore, not protected.

Good luck. 🙂
