Installing fresh Windows 7 on HP all in one from USB

Product Name: HP EliteOne 800 G2 23-in Touch
Operating System: Microsoft Windows 7 (64-bit)

I have a system HP EliteOne 800 G2 23-in Touch GPU AiO. It already have Windows 10 installed in it. I want to format my system, create new partitions and install Windows 7 on it.  

   When I try to boot from USB, it halts on first screen as shown in the image and can't go furthe (mouse, keyboard and touch do not work here). Even I try different options for Boot menu like secure Boot and Legacy Support. How do I proceed?

Re: Installing fresh Windows 7 on HP all in one from USB

Hi:

 

You need to run this tool to put the required USB3 drivers into your W7 installation flash drive.

 

There is a readme link on the page for how to use the tool.

 

https://downloadcenter.intel.com/download/25476/NUCs-Windows-7-USB-3-0-Creator-Utility

 

The reason you are having that problem is...

 

1. The Intel Skylake chipset your PC has, does not have native USB2 support until after you install the Intel chipset drivers, which you can't install until you get W7 installed.  That is why the USB2 ports don't work during the installation process.

 

2.  Your W7 installation media does not have USB3 support, which is why the USB 3 ports don't work during the installation process.

 

Since neither the USB2 or USB3 ports work during the installation process, that is why the KB and mouse stop working.

Re: Installing fresh Windows 7 on HP all in one from USB

Your desktop BIOS is probably expecting a GPT format Windows installer that has support for UEFI. Check in the diak manager to see if you disk is MBR or GPT format. If it is EFI, there will be a 100MB  EFI system Partition.

 

You can create one  with RUFUS.

All of the required drivers for Windows 7 are at the following link

Have you created recovery media yet? Be sure and do it before you format the disk

Erico, I try with your solution first because its looks simple but it didn't worked. I format the USB with GPT format using Rufus and create a bootable disk using ISO image of windows 7.  I don't know what other changes in BIOS do I have to make.  I try to enable both legacy and secure boot options but again it didn't worked.

Re: Installing fresh Windows 7 on HP all in one from USB

Installing an ancient operating system, Windows 7 is ancient, to a modern desktop PC is never simple.

 

The new generation of PCs are made for newer operating systems.

Re: Installing fresh Windows 7 on HP all in one from USB

Hi, @asifdegr8 :

 

Unless you use the tool I posted, you won't be able to install W7 on your PC.

 

I've already explained why the KB and mouse stop working when you try to install W7.
