Hi, @Cihan Akgol
Thank you for posting in Microsoft Q&A forum.
When we import MDT boot images into Windows Deployment Services, after update the Deployment Share, go to Windows Deployment Services, Boot Images, then go to Add Boot Image (LiteTouchPE_x64.wim) if Lite Touch Windows PE x64 is not already present in WDS:
If Lite Touch Windows PE (x64) is already in WDS Boot Images, right click on the image and choose Replace Image (and then select the location of LiteTouchPE_x64.wim).
