Answer:

Experiencing boot problems in a dual-boot Hackintosh setup after a power outage can be quite distressing. The situation you’re facing, where the system powers on but fails to load either Windows 10 or macOS, is not uncommon. The symptoms you’ve described—fans running, access to BIOS and OpenCore, but only loading screens without entry to the operating systems—suggest a few potential issues that could be at play.

Firstly, it’s important to isolate whether the problem lies with your hardware or software. Since you’ve already performed a series of hardware checks, including power cycling, CMOS reset, reseating the GPU, and verifying the PSU voltage, we can reasonably rule out simple power supply and connection issues. However, the possibility of GPU damage cannot be entirely dismissed. A sudden loss of power can sometimes cause electrical surges upon restoration, which can damage sensitive components like the GPU.

On the software side, OS corruption is also a plausible cause. Power outages can lead to improper shutdowns, which in turn can corrupt system files necessary for booting the OS. This might explain why the system halts at the loading screen—because it’s unable to proceed with damaged files.

Recommended Next Steps:

1.

Hardware Diagnostics:

If possible, test the GPU in another system or try a different GPU in your current system. This will help confirm if the GPU is the issue.

2.

Safe Mode:

Attempt to boot both Windows and macOS in Safe Mode. This can bypass some drivers and system functions that might be causing the issue.

3.

System Recovery:

Use the Windows Recovery Environment or macOS Recovery to perform system repairs. This can fix corrupted files and restore system stability.

4.

Data Backup:

If you can access your drives via an external enclosure or another computer, back up your data before attempting further repairs.

5.

Clean OS Installation:

As a last resort, consider a clean installation of both operating systems. Ensure you have backups before proceeding.

In conclusion, while the exact cause of your system’s boot failure post-power outage is not immediately clear, following these steps should help you narrow down the issue. If the problem persists, seeking assistance from a professional technician who can provide hands-on diagnostics and repair might be necessary.

Remember, when dealing with complex systems like a Hackintosh, patience and systematic troubleshooting are key. Good luck!
