DISM Restorehealth source files can't be found

Hi there! It seems like you're experiencing some issues with the DISM /restorehealth command on Windows 10. Let me try to help you out.
Firstly, it's great that you're trying to repair the Windows 10 installation using DISM. However, the command you used seems to have a small issue with the source path. Instead of using "install.esd" at the end, try using "install.wim" as the source file. The corrected command should look like this:
dism /online /cleanup-image /restorehealth /source:f:\sources\install.wim
Make sure the virtual drive letter (in this case, "F:") matches the actual drive letter where the ISO file is mounted.
If you're still encountering the same error after trying the corrected command, there are a few troubleshooting steps you can follow:
1. Double-check the path: Ensure that the ISO file is indeed mounted correctly and accessible from the specified drive letter. You can try navigating to the virtual drive in File Explorer to confirm.
2. Verify the integrity of the ISO file: The ISO file you downloaded may have been corrupted during the download process. Try re-downloading it from Microsoft's website and see if that resolves the issue.
3. Use an alternative source: If the ISO file is still causing issues, you can try using a different source, such as a Windows installation DVD or USB drive. This source should have the necessary files for DISM to complete the operation.
4. Try an offline repair: If all else fails, you can perform an offline repair by creating a Windows 10 USB installation media (using the media creation tool) and booting from it. From there, you can choose the "Repair your computer" option and attempt to repair the corrupted system files.
I hope these suggestions help you resolve the issue and repair your Windows 10 installation successfully. Let me know if you have any other questions!
