1. Check the cable connecting the display

The first step is to check the cable connecting your display. It might be loosely connected, which could be causing the black screen issue. Disconnect and reconnect the cable. Also, check the cable physically for any damage. If the cable is damaged, replace it.

Alternatively, you can also use the DisplayPort cable and see if it helps. If the DisplayPort cable is unavailable, you can use the DP to HDMI connector.

2. Perform a hard reset

If changing the cable does not fix this issue, the next step is to perform a hard reset. Go through the following instructions:

1. Force shut down your computer.
2. Disconnect all the peripherals.
3. Press and hold the power button for 30 seconds.
4. Turn on your computer.

Now, reinsert the bootable USB flash drive and start Windows installation.

3. Update graphics drivers in Safe Mode

Boot Windows in Safe Mode and then update the Graphics drivers.

4. Create the installation media again

The installation media you are using to install Windows might be corrupted, causing a black screen during installation. This may happen if the Windows installation media is not created properly. Create the bootable USB flash drive with the Windows installation media again, then reinstall Windows. You will need a working computer for this.

To create a bootable USB flash drive with Windows installation media, you can use Microsoft Media Creation Tool or a third-party tool, such as Rufus.

5. Disconnect other hard drives

If you are installing Windows on a separate SSD, you can disconnect other hard drives. Open your computer case and disconnect other hard drives. If this works, you can connect the hard drives after installing Windows.

6. Reset BIOS

Misconfigured BIOS settings may also cause this problem. The best fix in this situation is to reset the BIOS to the factory default settings. Enter your system BIOS using the right BIOS key and then reset the BIOS to default.

If this does not work, you can also try clearing the CMOS. Follow these steps:

1. Open your computer case.
2. Locate the CMOS battery and gently pull it out of the socket.
3. Wait a few minutes, then reinstall the battery with the correct polarity.

Additionally,  you may temporarily disable Fast Boot and Secure Boot. Now, check if you can install Windows.

7. Check the QLED indicators on your motherboard

The issue might be due to a hardware fault on your motherboard. Motherboards have QLED indicators that light up when a particular hardware fault is detected. Open your computer case and then install Windows. See if any QLED indicator lights up during this process. If yes, that hardware component is failing.

There might be other underlying hardware faults with your system. Take professional help for further assistance.
