I'm at a loss with this one, and I'll do my best to explain what we're seeing.
We have HP Z240's (only happening with them specifically so far) SFF, that will appear to image either over PXE or with a USB bootable using SmartDeploy, but fails on first reboot and is stuck at the login screen with a big red X on the network icon in the corner (and our default Administrator password we configured on our image won't work either).. I've reconfigured the BIOS before imaging for UEFI. I thought maybe it had something to do with MBR vs GPT partition info, but the disks are set for GPT.
This only seems to be happening on some of the original Z240's we got with Windows 7 on them from HP when they first came out (I believe the IT department asked for downgrades from Win10 back then). When we try to use SmartDeploy to put Windows 10 on them (fresh installs, not upgrades), they fail on the first reboot weirdness from above. However, if we swap the SSD (regular 2.5") with one from a newer Z240 or a new Z2 desktop, it images just fine. Has anybody experienced this? After much googling, I feel like there's some UEFI/AHCI SATA issue with the HP BIOS settings I'm missing, maybe? Because the SmartDeploy WinPE boots and starts the imaging process, and only fails at the reboot where the hard drive is now the boot drive. I can't tell if this is a BIOS issue or something I'm missing in SmartDeploy? We do set the checkbox for UEFI/Secure Boot.
Here's the fun part, if I boot using my Windows 10 bootable USB I created with a Win10 ISO from microsoft, it boots, installs windows 10, reboots and let's me go through the set up properly and gets me to the desktop like normal, on the network and all that.
Anybody seen this? What could it be? The IT manager has talked of just buying a bunch of new SSD's to replace these, but I'd like to avoid spending that money if it's not necessary.
Thanks for any suggestions all.
