Installation of Windows 7 , the keyboard and the mouse not working

[BuAli]

I have purchased HP All-in-One - 20-c023w (ENERGY STAR) but I do not like Windows 10 so I tried to install windows 7 but when I get to the windows 7 installation screen, the keyboard and the mouse are not working. Please help me to solve this problem.

Hi:

Starting with all PC's that come with the Intel Braswell and Skylake chipsets or newer, W7 does not have the required chipset or USB drivers in order to install.  That is why the KB and mouse freeze up.

Windows starts with the "PreBoot environment" this lacks chipset, USB2/3.0 driver support, and only has just the bare minimum to get a graphical setup screen up and running.

Once you enter in the necessary information into the preboot (such as install location, partition size, and some other misc info) it passes the information into the main windows OS install (install.wim), and again this installer has no USB 3.0 driver support.

To get a working install, extract the intel USB 3.0 driver for the motherboards chipset, to access the inf files, then also do the same to the intel RST driver  (10.1.0.1008) or the latest for the NUC,10.1.1.14. The correct driver rev depends on the hardware.

Then slipstream the USB 3.0 driver into both the PXE Preboot and the Install.wim setups, and the chipset inf into the install.wim using NTLite

Now you should have a win 7 install setup that has USB 3.0 support in preboot, and windows 7, and the setup had the proper chipset RST information

Note that the intel usb driver is OS and chipset specific depending on the system you have (check with intel for the one that matches your OS/chipset)

The following drivers should work for most Intel Braswell/Skylake and newer chipset platforms…

To supplement Paul's excellent reply, please note that Microsoft will terminate all support for Windows 7 in January 2020 -- less than 17 months from now.  At that time, you will need to install Windows 10, to run a "supported" operating system.  Already, I am finding web-sites that state that they are not compatible with Internet Explorer 11 (the final release that works under Windows 7), and it's getting worse.

So, to avoid a lot of work in January 2020 doing an upgrade to Windows 10, I recommend that you install Windows 10 today.

Note that Microsoft has stated that there never will be a "Windows 11" -- Windows 10 (or some variant of Linux) will be the primary operating systems, in the future.
