When I install Sophos Endpoint Defence on an Amazon provided AMI; and then create a custom AMI from it; why do EC2 instances display an error dialog on boot 'Windows could not finish configuring the system'?
In my case I used EC2 Image Builder to run SophosSetup.exe /quiet
I then had it run a series of commands provided in Sophos Sysprep.txt
from https://support.sophos.com/support/s/article/KB-000035040?language=en_US
However after creating the AMI I was unable to boot any EC2 instances from it.
The Troubleshooting > Take Screenshot
function allowed me to view the error dialog on the screen.
