I am stumped here. I received ~60 PCs about 9-12 months ago to image and deploy out. About 6 months ago, I finalized the image and started deployments. I placed out ~20 of the machines, without any major issues.
I just (1 month ago) imaged up the remaining 40 machines, again without issue, was able to boot them, add them to the domain, have Group Policy Install managed software, perform windows updates. Then suddenly, without a known cause or reason, each of these machines stopped booting successfully. They freeze up on the Dell UEFI Boot Logo, without the spinning pinwheel, and eventually go to a solid blue screen that says "A required device isn't connected or cannot be accessed. Your pc needs to be repaired", which then times out and the system shuts down
Some things to know:
- None of the previously deployed systems ever exhibited a behavior like this
- No system that was recently imaged has escaped this issue
- All systems are part of the original, identical batch of PCs (same models)
- We are running Windows 10 Pro v1511
- Systems can boot successfully when secure boot is turned off (UEFI left on)
- Some (possibly all) of the systems displayed a TPM message during reboots (A configuration change was requested to enable, activate, and allow creation of an operator authentication value that permits temporary deactivation of the TPM This action will turn on the computer's TPM (Trusted Platform Module)
Ores F10 to enable, activate, and allow creation of an operator authentication value that permits temporary deactivation of the TPM Pres Esc to reject this request and continue
- Most systems had F10 pressed. Some timed out before I could press F10, and I assume when the Esc route
- Spoke with manufacturer (Dell) and they thought it may be the TPM version (Systems shipped with 1.2). They had me update the firmware to 2.0. No change.
- No changes made to the image since I started imaging
- No error codes in Event Logs referring to what is going on. No evidence that system is even having failed boots
- Systems are Dell 3040 Micros
- Systems came with Win 7 on mechanical drives. They were upgraded in house to additional RAM and SSDs (all part of original purchase)
