    Hi, if you don't have an internet connection, you can use the DISM command with an offline Windows image to restore your system on a Windows 7 OS. Here's how you can do it:

    Prepare the Windows installation media: You'll need a Windows 7 installation DVD or a bootable USB drive with the Windows 7 installation files.

    Boot from the installation media: Insert the installation media into your computer and boot from it. You may need to change the boot order in your BIOS/UEFI settings to boot from the DVD or USB drive.

    Access the Command Prompt: Once you boot from the installation media, select your language preferences and click "Next." Then, click on "Repair your computer" and select "Command Prompt" from the System Recovery Options.

    Use the DISM command: In the Command Prompt, you can use the following DISM command to restore the system:

    dism /image:C:\ /cleanup-image /restorehealth /source:D:\sources\install.wim
    Replace C:\ with the drive letter of your Windows installation.

    Replace D:\sources\install.wim with the path to the install.wim file on your installation media.

    This command will use the install.wim file from your installation media to repair the Windows image on your system.

    To use DISM on an Acer laptop without internet access on Windows 7, you need mount the image from it to perform offline repairs using the DISM command in an elevated command prompt; essentially, you're telling DISM to use the local image on your installation media to scan and repair system files. Steps:

    • Create a Windows 7 Installation Media:
      • Download a Windows 7 ISO file from a trusted source.
      • Use a tool like Rufus or the Windows Media Creation Tool to create a bootable USB drive or DVD with the Windows 7 ISO image.
    • Access the Command Prompt with Administrator Privileges:
      • Boot your computer from the created installation media (usually by changing the boot order in BIOS).
      • Select "Repair your computer" option during the setup process.
      • Choose "Command Prompt" with administrator privileges. 
    • Mount the Windows Image:
      • Identify the image: Use the command dism /Get-ImageInfo /ImageFile:C:\sources\install.wim to find the index number of the Windows image you want to use. 
      • Mount the image: Execute the command dism /Mount-Image /ImageFile:C:\sources\install.wim /Index:1 /MountDir:C:\MountPoint
      • Replace the placeholders:
        • C:\sources\install.wim: Path to the Windows image on your installation media. 
        • Index:1: The index number of the image you want to use. 
        • C:\MountPoint: A temporary directory where the image will be mounted. 
    • Run DISM to Repair:
      • Execute the command dism /Image:C:\MountPoint /Cleanup-Image /RestoreHealth to scan and repair corrupted system files within the mounted image. 

    I hope this helps! If this was useful, please hit 'Yes' or 'Like'! Thanks! 😊

    So it is NOT possible to run DISM with Acer supplied factory disks or using the factory Acer Recovery Partitions.

    Thanks anyway, Tracey
