EpeUefiBootcode.cpp: [0xEE020002]

Context:
- HP EliteBook 840 G3 laptop
- NVMe SSD
- Relevant agents:
    - Drive Encryption 7.2.4.2
    - Drive Encryption Go 7.2.4.2
    - Drive Encryption: Windows 7.2.4.2
    - McAfee Agent 5.5.1.388

Issue:
- The following booting error has appeared out of the blue and has rendered the laptop unbootable:
"Unexpected exception in EpeUefiBootcode.cpp: [0xEE020002]".

Actions performed:
- Generated bootable USB drive with EETech-7.2.4.2 in standalone mode.
- Extracted xml decryption file from the ePolicy console and added to the bootable USB.
- Booted laptop, enabled USB, authenticated with xml file and authorized with Code of the Day (COD) generated by EETechCode.exe

Observations:
- The option to "Set Boot Disk" only shows "Disk 1" without any indication if it is referring to the internal SSD or the external bootable USB.
- The option to "Remove DE" starts but does not progress whatsoever.
- The "Workspace" is completely empty (all zeroes).
- The "Disk Information" makes more or less sense and looks healthy (I'm not a HDD expert though).
- The option to "Emergency boot" complains about the fact that "The current MBR contains invalid McAfee Drive Encryption Disk Information". The "Search" starts but does not progress whatsoever.
- Option to "Restore MBR" (Original MBR + Keep the current PT) performs satisfactorily but does not fix the issue.

Status:
- Stuck here. Not wanting to start clicking random options and end up making things worse. Would greatly appreciate any kind of advice leading to fixing this issue. Thanks a lot!

Re: EpeUefiBootcode.cpp: [0xEE020002]

@squeakyWheel thanks for choosing community forum.

I would like to know what happened / performed before observing this issue?

If you access sector 0 and count 1 in workspace, what do you see in the right top corner? is it safeboot MBR or Windows?

Restore MBR + keep current PT should not have performed at this point. this changes the MBR.

Seems to be sector / HDD issue....however, I would try to clone the disk using sector by sector option then try to decrypt.
