BIOS is not called. Win 10 not load. Black screen

[Eli9292]

Due to a registry issue, I reinstalled Windows 10 on HDD from another device. There is no download when connected to my HP computer. The BIOS is not called. I think the problem is in UEFI, but I can't figure out where it was.

It is not clear just what this means : "I reinstalled Windows 10 on HDD from another device"

If that means you copied it from one PC to another instead of using install media, that is why there is a problem.

Assuming the PC had Windows 10 in the past, you can make the install media.

If you need the install media for Windows 10, you can make it from this Microsoft download

https://www.microsoft.com/en-us/software-download/windows10

With a working PC, scroll down to the "Using the tool to create installation media"
and then follow the directions. You can make either the DVD or USB. Use this new media to install Windows 10.
When the install asks for the product key, click the "I don't have a product key" option to continue,
then the install will continue. It will be activated once it connects to the internet, as it uses a digital key.

In order to set the BIOS to boot from either the DVD or Flash drive,  Start tapping the Esc key BEFORE starting the PC and then press the start button.
Keep tapping the Esc key until a popup menu shows. Then pick F9 to pick the boot device.  The process should then continue to install Windows 10
