I found some really weird issue with the EEPC v7.0.2
I had some laptops in my network worked with EEPC7.0.0 and ePO 4.6.6
Now i start update proces to ePO5.0 ande EEPC7.0.2
I migrated some device form one epo serwver to other and deploy newest version EEPC, but in one case i had some problem.
After EEPC upgrated on this machine and restart the computer i cannot run windows7. I can provide credentials for login to mcafee (PBA screen), then i see the message "running windows 7" but the operating system not start.
When i restet it and unplug network cable, the laptop can run windows.
Sorry for my english.
I found solution.
it can be fixed in some other ways:
solution 1.) Disable "Always enable pre-boot USB support" in the policy->Boot Options
solution 2.) Update the BIOS version.
solution 3.) Disable USB legacy support in BIOS
This case was with DELL Latitude Laptop
As a side note - you mentioned you are ein the progress of going to 5.0 - please make sure you have right patch level :
The minimum supported version of ePO is version 5.0.1. There is no support for ePO v5.0.0.
The following minimums also apply:
Don't you have to have the machine imaged with UEFI in order to be able to disable pre-boot USB support? Currently we are not imaging machines with UEFI and it cannot be changed without rebuilding the machine
