System frozen at boot, repeatedly cycling through BIOS settings.
Hello everyone, my gaming PC started up properly after work yesterday, functioning just like it has for the past few years. After a short break, I returned and saw the BIOS screen appeared. No settings were lost, everything seemed normal, yet when I exited the BIOS interface it restarted directly into it instead of launching Windows. My SSDs appear correctly in the NVME devices but not in the Boot tab. In the next Boot menu the OS type was changed to another system, and the PK state disappeared. Switching to Windows UEFI resolved this again, but the same pattern continued. The CSM is turned off; enabling it makes the drives show up in the Boot menu, though they still don't load into Windows. System details: AMD RYZEN 5950X, ASUS Crosshair Extreme 32GB, GSKill 3800CL14, Samsung OEM 2TB Gen4 NVMe SSD. I've tried several fixes: reset BIOS, switched to alternate BIOS, adjusted Secure Boot settings, unplugged all devices before booting, removed half the RAM and other SSDs—nothing changed. This suggests a problem with TPM, GPT, or MBR partitioning. I'm confident the last installation was on a GPT partition, which I had to manually adjust when switching to PCI-e4 graphics with resizable bar support. I haven't made any changes yesterday that could have caused this. Could Windows updates be responsible? Any suggestions for further steps? If none work, a fresh Windows install might be necessary, but I'd prefer not to risk it right now.
It seems there was an unexpected update that messed up Windows. The system might now be damaged and can't load properly, so the boot files are gone. Reinstalling Windows could be the best solution.
