How to Fix Using DISM Windows to Go Using the Windows 11 USB Installer?

Question

Hello Microsoft friends. When I boot to the Windows 11 USB Installer and use the Command Prompt to fix the Windows to Go on an external drive, when I type on the Command Prompt: dism /Image:G:/Cleanup-Image /RestoreHealth it displays the error 2 which I think means 'Access Denied'. Drive G: is the mount point of the Windows to Go external drive. What could be the commands I should use to make DISM fix my Windows to Go installation (the hardisk is plugged it onto an external USB hub)? Thank you in advance. God bless you. Revelation 21:4

Answer 1

Hello The error code 2 you’re encountering typically indicates that the system is unable to access the image. Here are some steps you can try to resolve this issue:   Check File/Folder Permissions: Make sure you have Read permissions on the Windows directory/folder. Optimize and Defragment Drive: Run Disk Defragmenter to rearrange fragmented data, which could potentially trigger the DISM error 2. Temporarily Disable or Uninstall Antivirus: Third-party security software could interfere with some processes on your computer. Make Sure Windows is Up to Date: It is important to make sure Windows is updated, so that you know you’re running the latest version of the DISM tool.   If the issue persists, you can try the following commands in the Command Prompt (run as administrator):   To check the health of the image: DISM /Online /Cleanup-Image /CheckHealth   To scan the health of the image: DISM /Online /Cleanup-Image /ScanHealth   To restore the health of the image: DISM /Online /Cleanup-Image /RestoreHealth   Please replace /Online with /Image:G: if you want to target the Windows to Go installation.   If the RestoreHealth command fails, you can specify a source to repair the image. Replace <source> with the path to your known-good files (this could be a mounted Windows image or a side-by-side store):     DISM /Online /Cleanup-Image /RestoreHealth /Source:<source>     Again, replace /Online with /Image:G: if you want to target the Windows to Go installation.   Remember to replace the drive letter G: with your actual drive letter if it’s different.
