You’re looking for the missing repair content after RestoreHealth fails with 0x800f0915. DISM could not locate files matching the installed Windows image. The key detail is Windows 11 25H2 build 26200.8894. Microsoft notes that a repair source older than the target’s cumulative-update level can fail. First run Windows Update, install everything offered, restart, and retry DISM /Online /Cleanup-Image /RestoreHealth in an elevated Terminal. If it fails, open Settings > System > Recovery and, under Fix problems using Windows Update, choose Reinstall now. That downloads a repair version of the same Windows release and preserves apps, files, and settings. Keep the laptop powered and online; back up data first. If that option is absent, use Microsoft Windows 11 25H2 installation media matching Home Single Language, language, and architecture; launch setup.exe from inside Windows and proceed only if Keep personal files and apps is offered. Do not point DISM at older media.
