Operating System

[Kevin445]

Hello, I recently purchased a HP Z2 Tower G9 Workstation Desktop PC. I have upgraded the M2 from 512GB To 1TB. Therefore it has no operating system. I have windows installed on a USB, and the computer recognised the M2 and the USB flash drive. However, when I go to select a drive to download windows on to, nothing shows. It also does not let me update the drivers…. Without an operating system. I really have no idea what to do. Anyone able to help with this would be much appreciated. Thanks in advance.

Hi:

You have to load the Intel storage controller drivers at the screen where Windows can't find any drives.

I have zipped up and attached the Intel storage controller drivers that Windows needs to find the drive.

The attached file is good for both W10 & W11.

Copy all of the files in both folders in the attached file to a USB flash drive.

Have the flash drive and your Windows installation media plugged into USB ports.

Boot from the W10/W11 installation flash drive.

When you get to the screen where no drives can be found, click on the Load driver option, browse to the flash drive with the storage controller drivers on it.

If you check the box, it will only include the compatible driver.

Click Next and Windows should find the drive and install.

Hi, I have tried this and unfortunately it is still not working for me

Hi:

That should have worked as I gave this solution to several other Z2 G9 owners and it worked for all of them.

A few related discussions:

Solved: Samsung 970 M.2 EVO PLUS not found in windows 10 on Z2 G9 - HP Support Community - 8561149

Solved: Couldn't find media driver to install Win 10 Pro - HP Support Community - 9097520

Solved: Drivers NVME win11 - HP Support Community - 9009189

The only other suggestion I can offer would be to use the HP cloud recovery client software to make a bootable USB recovery drive that will reinstall Windows, the drivers and the software that originally came with the PC.

Here is the link to the software download:

Here's the link for how to use the Client recovery tool:

Hi:

Unfortunately, I wouldn't be able to provide any additional assistance.

I don't have any idea why nothing has worked for you or what to do about it.
