The system failed to start due to a Gigabyte Bios issue.
I left my PC for a week and returned, but it won’t start Windows anymore. It shows a black screen with a flashing "_" and tries to boot all drives, including the NVMe with Windows installed. Pressing F12 doesn’t let me choose a boot device properly, and when I try to change the boot priority in BIOS, the screen freezes instead of unlocking. I’ve also used a new ISO for Windows and Linux, but it just asks me to pick a bootable drive or shows a black screen. My NVMe wasn’t set as the first boot priority, so I adjusted it in BIOS, but each time it freezes when I click the priority menu. Changing settings hasn’t fixed the issue.
The BIOS might become unresponsive in certain situations. Please share your complete system details. Consider: turn off Expo/XMP settings, eliminate any overclocking, install the newest BIOS version.
Blinking _ after BIOS indicates a non-bootable device or an incorrect priority setting. It might result from an automatic update while the computer was left on. Such updates can erase boot sectors. You could attempt to repair the boot area using the bootrec command in a command prompt to refresh the BCD. Recovery mode may also provide options to restore the system, either via a bootable USB installer or a cloned external drive. If these steps fail, consider reinstalling Windows. Alternatively, you might try reading the drive from Linux to recover vital files first.
It seems the system is stuck in BIOS mode. The issue might be hardware-related, such as an overheated SSD causing damage that prevents proper communication with the BIOS. Try disconnecting the problematic drive and connecting another storage device, like an external drive or installation media. Test with a bootable installation to see if the BIOS functions correctly.
I refreshed the BIOS but it didn’t resolve the issue. The system specs are: R5 7600X, 32GB DDR5 Vengeance, B650 Gigabyte X-AX v2. Initially there were no overclocks, and I disabled and enabled XMP to test. I removed the NVMe drive using Windows and tried a bootable USB, but the same problem persisted—either it ignored it or prompted to choose another boot device.
I've already tried, but good news the warranty still has one year remaining.
I don't perceive alternative options beyond changing the current item.
