Hello @Juanalberacosta
Welcome to the HP Support forum.
Can you enter/load the built-in recovery in the internal partition ? Here is how:
1. Please, shutdown the computer using the power button
2. Power it on.
2.1 As soon as you press the power-on button, immediately begin hitting the Esc button (like tap-tap-tap).
This should open a HP Startup Menu which may look similar to this one

3. Choose/press F11 for System Recovery options.
The computer should boot from it's recovery partition to open you various recovery options. Note, that F11 option will only work if the recovery partition is there (not deleted) and intact. From there, you have prenty of options to choose from. Every HP computer comes with recovery partition present to assist in tough moments.
4. Go to Troubleshoot > Reset this PC
or Troubleshoot > Advanced options > HP Recovery Managed (Recovery Manager)
5. Follow the on-screen instructions
Does this work and if not, where it fails ?
