I am installing Windows Hyper-V Server Core 2019 to a 512GB NVMe SSD via USB on a new Dell Precision 3660 tower. The installation proceeds as normal, first copying installation files to the NVMe, restarting, doing the spinning dot churn for setting up the system, and another automatic restart. After that second restart though, the spinning dots appear but never spin - the system just hangs and no drive activity is indicated on the front panel. Restarts have not yielded any results. I have tried setting Windows to start in Safe Mode, and, while it gets somewhat farther, it alerts that "Windows cannot complete installation in Safe Mode. To continue installing Windows, restart the computer".
Restarts with "Enable Boot Logging" does not yield any logs, presumably because startup never advances past the point where the logging is initialized.
I have successfully installed Windows 11 to that same machine subsequently, and also, as a test, added the Hyper-V feature, created a VM and installed Hyper-V Server Core 2019 to it! This installs fully with no issue.
Since I now have 2 instances of Hyper-V Server Core installations (the baremetal one and the virtualized one on Win11), I've compared the C:\Windows\Panther\UnattendGC\setupact.log and it shows that WinDeploy never manages to launch again subsequent to the restart, and hence OOBE never starts either. No errors are reported and the logs are identical up to the point where the failed one ends.

Does anyone have any ideas on why this isn't working, or leads as to where I can search next for the source of the error?
