Hello @Dado_ 

Thank you for posting.

Make sure the Windows is properly written and that the memory card has been configured properly.

• Would you be able to re-create the SD card and make it bootable again ? Make sure you re-download the Windows 10 ISO and that you follow the instructions from here (this website) >> https://answers.microsoft.com/en-us/windows/forum/windows_10-windows_install-winpc/how-to-prepare-bo...

After that, try booting again.

* Important - make sure you follow the steps in the instructions.

If you have created a bootable SDHC drive, have you tried this:

- press and hold the power-on button of the PC for at least 5-6 seconds to completely shut it down ?

- Insert the drive in

- Press the power-on button once to start the PC and

- Immediately start hitting F9 repeatedly

F9 will open HP Boot menu and it will list all options available to boot from at that moment . Do you see your SDHC device there ?

• If you still cannot see it there,

Would that be an option for you - would you be able to try with a plain USB flash drive  ?

You need one at least 8GB in size.
