Stuck at the screen with words "Press the ESC key for Startup Menu" on the bottom

[TWOFACE]

I try to do a BIOS update myself (stupid move) one day, and I left it to finish. Ten minutes later, it is stuck on the HP logo. If I press ESC in the beginning, it will go to a black screen and it will show the basic information of the computer (the information about processor and memory). At this black screen, it also shows "Press the ESC key for Startup Menu" on the bottom and it will show "startup menu" at the bottom right corner if I press ESC, but it does not respond to any other actions. If I press F10 in the beginning, it will also go to the same black screen, and it will show "setup" at the bottom right corner. If I do Ctrl+Alt+Delete, it will go back to the HP logo. I already saw someone with the exact some issue as me, but my computer is an all-in-one. I will be very grateful to anyone that helps!

• Turn off the computer, and then connect the power cord.
• Press and hold the Windows key and the B key at the same time, and then press and hold the power button for 2 to 3 seconds.
• Release the Power button but continue pressing the Windows and B keys. You might hear a series of beeps.
  The HP BIOS Update screen displays and the recovery begins automatically. Follow any on-screen prompts to continue the startup to complete the recovery.
  
  • If the HP BIOS Update screen does not display, repeat the previous steps but press the Windows key and the V key. If the screen still does not display, your computer might not support the feature or there is a hard drive issue. Continue to the next step to install a BIOS recovery file from the HP website.
  • If the Power light turns off, the Power button was held too long. Repeat the previous steps, making sure to hold the button for only 2 to 3 seconds.

AND/OR
First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

AND/OR - Windows Logo key + Ctrl + Shift + B
(This key sequence actually restarts you graphics drive(W10 only).)

AND/OR - If you’re using multiple displays, try projecting video to a different monitor.
Press the Windows Logo key + P, select a display, and then press Enter.

I tried the windows+b key, it beeped 8 times, and after about a minute, it is back on the HP logo. I also tried the hard reset, but it does not seem to work.

This is the post that has exact same porblem as mine.

but I don't think my motherboard have CMOS settings.

Is there another way, or is this a hardware failure?

No I dont see any jumpers.

So make the Flash Drive and Boot from that.

Could you be more specific, I am not exactly a computer boy lol. Do you mean make a USB drive copy of BIOS and redo the BIOS update? I may have heard that somewhere about booting the computer using another one.

Step 2: Create a USB recovery drive

Is what I mean.
