Follow these steps to successfully reinstall Windows 11 when a USB-based installation fails:

1. Confirm the correct recovery/installation method
   • If the PC still boots into Windows 11: prefer an in-place reinstall that keeps files and apps:
     1. Open Settings > System > Recovery.
     2. Under Fix problems using Windows Update, select Reinstall now.
     3. Follow the prompts and keep the PC plugged in and online. This reinstalls the current version of Windows while preserving apps, documents, and settings.
   • If the PC does not boot or Windows is badly corrupted: use proper installation media and perform a repair install or clean install.
2. Recreate the installation media correctly If the USB install fails, the media may be corrupted or incorrectly created. On a working Windows PC:
   1. Go to the official Windows 11 download page and use the Media Creation Tool to create installation media.
   2. In the tool, choose Create installation media for another PC.
   3. Let it detect the correct edition and architecture, then select USB flash drive.
   4. Let the tool download and write Windows 11 directly to the USB. This avoids manual ISO copy errors.
   If using an ISO instead:
   • Download the Windows 11 ISO in the same language and edition as the installed Windows.
   • Use the ISO on a working PC to run Setup.exe (for an in-place repair) or to create a bootable USB using the Media Creation Tool.
3. Try an in-place repair install (if Windows still starts)
   1. On the affected PC, copy the Windows 11 ISO locally.
   2. Disconnect from the internet and unplug all nonessential external devices.
   3. Temporarily disable any third-party antivirus.
   4. In File Explorer, double-click the ISO, then run Setup.exe.
   5. Choose the option to keep files and apps. This is “like an update” and often fixes update/installation errors without wiping data.
4. Perform a clean install only if necessary If the system will not boot or repair options fail, a clean install may be required:
   1. Boot the non-working PC from the USB installation media (check the PC manufacturer’s instructions to change boot order if needed).
   2. When Windows 11 Setup appears, choose language and keyboard settings and select Next.
   3. Select Install Windows 11.
   4. If prompted for a product key, select I don’t have a product key, then select the same edition that was previously licensed.
   5. Proceed with installation. Be aware a clean install removes personal files, apps, manufacturer customizations, and settings, so back up data first if possible.
5. If installation still fails
   • Ensure there is enough free disk space and that the disk/SSD is healthy.
   • Remove unnecessary external hardware during installation.
   • If using VPN or location-hiding tools to download media, disable them, clear the browser cache, and download again.
   • If repeated failures occur even with freshly created media, contact Microsoft Support for deeper troubleshooting.
