Ah, the joy of troubleshooting task sequences in Config Mgr! I spent a while on this one, having one task sequence performing a build and installing some software and another one while deploying that image. The deploy should also install driver applications, the one we love to hate, like bluetooth and fingerprint readers. Well, it failed multiple times to my great annoyance. Why it fails? Because software installations take place in the full OS, which occurs AFTER the step “Setup Windows and Config Mgr”. Once I moved my installations to after that, it worked flawlessly.
