Similar situation, hooked up an Monitor and it appeared that the SSD was bad, stating when 25.7 was installed that it needed to recover clusters etc. then eventually would not boot. Uninstalled 25.7 and reinstalled 25.1.12 and no issues 2 days and counting. May try removing the Intel Microcode later and trying to install 25.7 again, spent an entire day troubleshooting. I am running the Glovary Mini PC with N100 Alder Lake CPU
