I updated the BIOS on my custom-built PC, and afterward it stopped loading Windows. Instead, it enters automatic repair, says the computer ran into a problem, and then fails to fix anything. My system has an MSI B650 Tomahawk WiFi motherboard, a Ryzen 7 7800X3D, 32GB of Corsair DDR5 memory, and a Samsung M.2 SSD containing Windows. The BIOS boot menu shows "UEFI Hard Disk: Windows Boot Manager" for the Samsung drive as the first boot option. The PC had occasional crashes before the update, which is why I installed the newer BIOS. What BIOS settings should I check, and should I consider rolling back the update?

Memory settings may also have been reset or become unstable after the BIOS update. Load the motherboard’s default settings, then try booting with the RAM at its standard speed instead of enabling an overclocking profile. If it still fails, test with one memory stick at a time and make sure the modules are fully seated.
A BIOS reset can change settings that Windows depends on. First confirm the system is using UEFI mode and that the Samsung M.2 drive is detected. The fact that Windows Boot Manager appears in the boot list is a good sign. Also check that the storage configuration has not changed and that the correct M.2 slot is enabled. Avoid switching between UEFI and legacy/CSM modes randomly, since that can prevent Windows from booting.
Since the update was intended to improve stability, I would not immediately roll it back. First recheck the BIOS configuration and try Windows Startup Repair or System Restore from the recovery menu. If the new BIOS itself is causing the problem and the previous version was stable, rolling back to the earlier version may be reasonable, but use the motherboard’s supported flashback method and do not interrupt the process.
The computer was usable before the update, although it had occasional crashes. I’ll try restoring the BIOS settings and Windows recovery options before deciding whether to revert.
The Samsung drive does appear as Windows Boot Manager under the UEFI boot options. I’ll check the UEFI, CSM, and storage settings next.
