Hi,
Have you followed the following steps?
Install the image on the disk and boot into Windows.
At the command prompt, run bcdboot.exe. This copies the boot files from the Windows directory and sets up the boot environment.
Before installing any additional updates, install the September 23, 2019 re-release of KB4474419 and KB4490628 for Windows 7 SP1 and Windows Server 2008 R2 SP1.
Restart the operating system. This restart is required
Install any remaining updates.
You must restart your device after installing all the required updates, before installing any Monthly Rollup, Security-only update, Preview of Monthly Rollup, or standalone update.
Also, I strongly recommends that you move to Windows 10 to avoid a situation where you need service or support that is no longer available.
Hope above information can help you.
