@Laucheintopf, Welcome to the HP Support Community!  

Thanks for reaching out about your query regarding Black Screen and 8 Beep Tones After BIOS Update! 

We're thrilled to have the opportunity to assist you and provide a solution.  

If you encounter an issue where your HP PC fails to start with 8 beep tones and a black screen after a BIOS update, you can try the following troubleshooting steps to recover the BIOS:

Power Cycle the PC:

• Disconnect the power adapter from the computer.
• Remove the battery if it’s a removable battery model.
• Press and hold the power button for at least 15 seconds.
• Reconnect the power adapter (and the battery if it's removable).
• Attempt to start the PC.

Perform a BIOS Recovery Using a USB Drive (if applicable):

• Create a BIOS recovery USB key. You can do this on another computer by downloading the BIOS recovery file from the HP Customer Support - Software and Driver Downloads page.
• Power off the PC experiencing the issue.
• Insert the USB drive with the BIOS recovery file into the USB port.
• Press and hold the Windows + B key, and then press and hold the power button for 2 to 5 seconds.
• Release the power button but continue holding the Windows + B key until the BIOS recovery screen appears or you hear beeps.
• Follow the on-screen instructions to complete the recovery process.

Check for Hardware Issues:

• Remove any peripherals connected to the PC (e.g., USB devices, external monitors).
• Re-seat the RAM and check all internal connections.  

Hope this helps! 

Take care, and have an amazing day!
