Reinstallation of Windows 10 after 10 days following an upgrade to Windows 11

[WryThot]

My HP Notebook 15-da0073wm lost its touchscreen ability and after trying many solutions that did not work, I turned to the task of trying to do a clean installation of Windows 10.  In spite of following instructions on how to do this easily, my HP has resisted such and persistently returns me to Windows 11 minus my prior app installations.  And this results in me having to follow prompts to setup a Microsoft account, fill in Wi-Fi passwords, and even name the computer.  I am perplexed about what is going on.   I use a Windows 10 installaation USB stick accessed by me changing the boot order.  It leads me to where I have no choice but to install on a particular volume.  Consequentially, a Recovery screen eventually appears with the option to continue loading Windows 11 or some undesignated Windows installation. If I reach the point of designating a partition to install upon, only one is actually a possible choice.  Refreshing it does nothing to alter my eventual return to Windows 11.  All roads eventually take me to Windows 11.  I was under the impression this was a relatively easy task.  But if there is an easy way to do it, I have not encountered that yet.  The laptop once ran Windows 10.  I thought returning there might cure the touchscreen absence problem.  I simply seem to have made a new problem, the inability to get back to Windows 10.  Any insight would be appreciated.

Solved the problem of installing Windows 10 but the reinstallation did NOT restore the touchscreen drivers so that such app0eared in Device Manager.

The solution for reinstallation of Windows 10 simply required I use a correct technique for changing boot order so that the USB drive with Windows 10 upon it booted first.  For my HP notebook, I could enter BIOS by pressing F!0 reoeatedly at powering up the laptop.   In BIOS, I did not find BOOT at the top menu.   I used the right arrow to move the highlight over to System Configuration.  Hitting Enter, I at last found BOOT as an option and selected it.   That granted access to a screen where I could highlight in the UEFI area, a reference to USB Hard Diskette.  Highlighting that, I cliced ENTER.  Only then would the F5 and F6 keys shift that reference to another position in the list.  I moved the desired item to the top of the UEFI listings.  Then I pressed the keys that saved this new order and exited BIOS as well.  There are listed at the bottom of the menu.

After the normal Windows screen appeared, I used the shutoff icon to shut down the computer.  I put the USB stick in.  i powered up.  This time it went about the business of installing Windows 10.  When it finished and was on the verge of restarting, I pulled the USB drive out.  The computer restarted and at some point offered Windows 10 as the top choice.  Leaving it along, it proceeded to boot into Windows 10.  You dealt with several prompts and had to input a few things and decide whether to tic some boxes and enter some passwords but eventually you get it all sorted.  If you were smart enough to back up your personal files before installing 10, you can reinstall just the personal files.    

I post such details simply because I did not spy them elsewhere.  My BIOS screen did not match pictures.  And even the listing for the USB there  seemed to be named something a bit mystifying.  Maybe this will demystify some things.

Oops, I forgot to mention I had to go back in and return the boot order to the original order after this reinstallation.  I didn't want my USB stick to be the first thing booted, going forward.
