Hi, 

I have been sent the E7270 and E7470 as test units for our company and I have run into issues once Mcafee has encrypted the drives. Before Windows boots the above message appears.

I had the same issue with the E7250 and E7450 and a bios update was the eventual fix. I was on bios version 1.3.0 when the issue occurred. Tried flashing to the latest 1.4.2 and rebooting with no joy.

Currently re-installing the whole image again to see if 1.4.2 works but was wondering if anyone else has the same issue or if Dell are aware of the problem. 

EDIT: This was the mcafee link for the issue that occurred with the E7250 and E7450 https://kc.mcafee.com/corporate/index?page=content&id=KB83703&locale=en_US&viewlocale=en_US

Thanks!
