Welcome to our HP User Forum!
Two long beeps followed by two short beeps indicates a corrupted BIOS.
You should be able to use your HP AIO Hardware Diagnostic utility to roll back the BIOS to the previous version.
Please press the power button and immediately begin tapping the F2 key to summon the PC Hardware Diagnostic utility. Use the Firmware management to roll back the BIOS.
If that does not work, then consider creating a BIOS installer on a USB flash drive to boot to.
Hope this was helpful.
