Can't install Windows 7 Ent Ed. x64 on HP EliteDesk 800 G2 Mini.

We just received an HP EliteDesk 800 G2 Mini PC and we are having issues installing Windows 7 Enterprise Edition x64 in order to build our custom image.   We have slipstreamed and "DISMed" all the drivers into the boot and install WIM files and we still can't get past the screen where it usually requests a storage driver.  We have tried everything, does anyone else have any ideas.

Thank you.

Have you tried a regular dvd based install to make sure you don't have bad parts?

What OS did the computer come with ?  Does HP support Windows 7 on that machine?
TCNinjaAuthor Commented:
@John Hurst...  Yes,  It's downgrade-able.  The only thing that I leaning towards is that HP did not post the correct driver on their website.

@scott_silva...  Will try that tomorrow.

I would call HP Support. If it is truly downgradeable, drivers should be readily available.

Could be that the pre-imaged drive on the Elite Desk from HP contains a recovery partition in a format the Windows Installer doesn't recognize.  If you're reinstalling from an image anyway flatten the drive and remove any hidden partitions first.

i have had that problem too, and i found it was caused often by using an USB 3 stick
when i used an USB2 stick - i never had that problem
to me it seems the system recognises the usb3 drive, but has no driver for it

Did it come configured with 8?
You've got the BIOS set for a regular boot and not secure boot right?

Apparently the issue was driver related.  We used a different USB3.0 driver rather than what was posted on HP's site.  Go figure.  Here's my engineer's procedures in the event anyone else has this issue.

Here are the steps that were taken to image the HP 800 G2 PC mini:


1.       Create a USB flash drive Windows 7 installer      https://www.microsoft.com/en-us/download/windows-usb-dvd-download-tool

2.       The Windows 7 USB 3.0 Creator Utility helps to update a Windows 7 installation image to include USB 3.0 drivers

Download and run the Utility       https://downloadcenter.intel.com/download/25476/Windows-7-USB-3-0-Creator-Utility

•         Download and unzip the Windows 7 USB 3.0 Creator utility to a temporary folder on the Admin system.
•         Connect the USB device containing the Windows 7 image to the Admin system.
•         Right-click the file Installer_Creator.exe and select Run as administrator.
•         Browse to the root of the USB drive.
•         Click Create Image to begin the creation process.
•         Wait for the process to finish. It can take up to 15 minutes.

3.       Begin the Windows 7 install process accepting the Microsoft Software License Terms until you reach the following Windows Install screen with the setup error. (see attached image file)

•         Remove the USB thumb drive and insert it back in any of the ports (it can be the same port).
•         Choose Refresh.
•         Click Next to complete the rest of the install process.

***Note: Remove the USB upon reboot or it may start the install process again. Changing the boot order in the BIOS will also correct this.

3.      Begin the Windows 7 install process accepting the Microsoft Software License Terms until you reach the Install Windows partitions setup screen with the following error:

"Setup was unable to create a new system partition or locate an existing system partition. See the Setup log files for more information."

Remove the USB stick and insert it back in to any of the USB ports (it can be the same port).
Choose Refresh.
Click Next to complete the rest of the install process.

=============================================================================================

I will try the image on a USB 2.0 stick instead of a 3.0 stick to see if that eliminates the issue on the partitions setup screen.
