Fixed! Repair Windows 11 From USB [2024 Guide]

Creating a Bootable Windows 11 USB Drive

Repairing Windows 11 from a USB drive involves booting from the USB, accessing the Windows Recovery Environment (WinRE), and utilizing tools like Startup Repair, System Restore, Command Prompt (for SFC or DISM), or even performing a clean install. Ensure the USB drive is bootable and contains the Windows 11 installation files for a successful repair.

Before you can repair Windows 11, you need a bootable USB drive containing the Windows 11 installation files. I found the Microsoft Media Creation Tool to be the most reliable method.

1. Download the Media Creation Tool: Visit the official Microsoft website and download the Windows 11 Media Creation Tool. I always recommend downloading it directly from Microsoft to avoid potentially harmful files.
2. Run the Tool: Execute the downloaded file and accept the license agreement.
3. Select “Create installation media for another PC”: Choose this option to create a USB drive you can use on the problematic computer.
4. Choose your Language, Edition, and Architecture: The tool will often pre-select these settings based on your current system, but double-check them to ensure they match the version of Windows 11 you need to repair. This is particularly important if you’re repairing a different PC. For instance, I had to manually select “Windows 11” and “64-bit” when repairing a client’s machine that originally came with Windows 10.
5. Select “USB flash drive”: Choose this option to create the bootable USB drive.
6. Select your USB drive: Ensure the correct USB drive is selected, as the process will erase all data on the drive. I usually double-check the drive letter in File Explorer to prevent accidental data loss.
7. Wait for the process to complete: The Media Creation Tool will download the Windows 11 installation files and create the bootable USB drive. This might take some time, depending on your internet speed.

Alternative Method: Rufus

While the Media Creation Tool is straightforward, Rufus is a powerful alternative that offers more control.

1. Download Rufus: Get the latest version from the official Rufus website. I find it useful when needing to create bootable drives from custom ISOs.
2. Select your USB drive: Choose the correct USB drive in the “Device” dropdown.
3. Select your ISO file: Click the “SELECT” button and choose the Windows 11 ISO file you want to use. You can download the ISO from Microsoft’s website.
4. Configure the settings: Rufus will automatically configure the settings based on the ISO file. I typically leave the partition scheme as “GPT” for modern UEFI systems.
5. Start the process: Click “START” to create the bootable USB drive. Be aware that this will erase all data on the drive.

Booting From the USB Drive

With your bootable USB drive created, you need to boot your computer from it. This typically involves accessing the BIOS or UEFI settings.

1. Access BIOS/UEFI Settings: Restart your computer and press the appropriate key to enter the BIOS/UEFI settings. This key varies depending on your motherboard manufacturer (e.g., Delete, F2, F12, Esc). Refer to your motherboard manual or look for a prompt during startup. On my ASUS motherboard, it’s usually the ‘Delete’ key, while on my old Dell, it was F2.
2. Change the Boot Order: Locate the boot order settings in the BIOS/UEFI. This is often found under the “Boot” tab.
3. Set the USB drive as the first boot device: Prioritize the USB drive in the boot order. Save the changes and exit the BIOS/UEFI settings. Your computer should now boot from the USB drive. Make sure “USB Storage Device” or similar is selected.
4. If the system bypasses the USB: Some systems require you to specifically select the USB drive from a boot menu (often accessed with F11 or F12 during startup). Consult your motherboard’s documentation.

Repairing Windows 11 Using WinRE

After booting from the USB drive, you’ll be presented with the Windows Setup screen. However, you don’t want to install Windows. Instead, you want to access the Windows Recovery Environment (WinRE).

1. Select your language and keyboard layout: Choose the appropriate settings and click “Next.”

2. Click “Repair your computer”: On the bottom left of the setup screen, click “Repair your computer.” This will boot you into WinRE. I have occasionally seen issues with language pack mismatches causing WinRE to fail. If this happens, try booting with a USB created with a different language selection.

3. Choose an option: In WinRE, you’ll see several options:

   • Startup Repair: Automatically diagnoses and fixes common startup problems. This is often the first option I try.
   • System Restore: Reverts your computer to a previous point in time. This requires that System Restore was enabled before the issue occurred.
   • Uninstall Updates: Removes recently installed quality or feature updates that might be causing problems. I have had success with this option after problematic Windows Updates.
   • Command Prompt: Provides access to the command line, where you can run advanced troubleshooting commands like sfc /scannow or DISM /Online /Cleanup-Image /RestoreHealth.
   • System Image Recovery: Restores your computer from a previously created system image. This is only useful if you have a system image backup.
   • Go back to the previous operating system: This will revert to the previous version of Windows (if upgrading).

Using Startup Repair

Startup Repair is designed to automatically fix common boot problems.

1. Select “Startup Repair”: In the “Choose an option” screen, select “Startup Repair.”
2. Select your operating system: If prompted, select the Windows 11 installation you want to repair.
3. Wait for the process to complete: Startup Repair will scan your system for issues and attempt to fix them. This may take some time. I’ve seen it take anywhere from 5 minutes to over an hour, depending on the severity of the problem.
4. Restart your computer: After the process is complete, restart your computer and see if the issue is resolved.

Using System Restore

System Restore reverts your computer to a previous working state.

1. Select “System Restore”: In the “Choose an option” screen, select “System Restore.”
2. Choose a restore point: Select a restore point from the list. Choose a restore point that was created before the issue occurred. I usually sort by date to find the most recent one that’s likely to be good.
3. Confirm your restore point: Confirm the restore point and click “Next.”
4. Start the process: Click “Finish” to start the System Restore process. This will restart your computer.
5. Wait for the process to complete: System Restore will revert your system to the selected restore point. This may take some time.
6. Restart your computer: After the process is complete, restart your computer and see if the issue is resolved.

Using Command Prompt

The Command Prompt provides access to powerful command-line tools that can help you repair Windows 11.

1. Select “Command Prompt”: In the “Choose an option” screen, select “Command Prompt.”
2. Run the SFC command: Type sfc /scannow and press Enter. This will scan your system files for corruption and attempt to repair them.
3. Run the DISM command: If SFC doesn’t fix the issue, try running the DISM command. Type DISM /Online /Cleanup-Image /RestoreHealth and press Enter. This will download and replace corrupted system files from Windows Update. Note: you must be connected to the Internet for this to work correctly.
4. Restart your computer: After the process is complete, restart your computer and see if the issue is resolved.

Performing a Clean Install

If all other repair options fail, you may need to perform a clean install of Windows 11. This will erase all data on your hard drive, so make sure you have backed up any important files.

1. Boot from the USB drive: Boot from the USB drive as described earlier.
2. Select your language and keyboard layout: Choose the appropriate settings and click “Next.”
3. Click “Install now”: On the setup screen, click “Install now.”
4. Enter your product key: Enter your Windows 11 product key. If you don’t have a product key, you can skip this step if Windows was previously activated on the machine.
5. Select your operating system: Select the version of Windows 11 you want to install.
6. Accept the license terms: Accept the license terms and click “Next.”
7. Choose “Custom: Install Windows only (advanced)”: Select this option to perform a clean install.
8. Delete the existing partitions: Select each partition on your hard drive and click “Delete.” This will erase all data on the drive.
9. Select the unallocated space: Select the unallocated space and click “Next.” Windows will now install on this space.
10. Wait for the process to complete: Windows will install on the unallocated space. This will take some time.
11. Follow the on-screen instructions: After the installation is complete, follow the on-screen instructions to set up Windows 11.

My Experience & Quick Fix

I was recently working on a client’s PC that was stuck in a boot loop after a failed Windows Update. I tried Startup Repair, but it couldn’t fix the issue. System Restore also failed because restore points were disabled. I then tried running sfc /scannow from the Command Prompt, but it reported that it couldn’t repair some files.

My ‘aha!’ moment came when I realized I could use the DISM command to download fresh system files from Windows Update. After running DISM /Online /Cleanup-Image /RestoreHealth, I re-ran sfc /scannow, and this time it successfully repaired the corrupted files. The client’s PC booted up normally after that. The key takeaway here is: Ensure your machine has an internet connection when running DISM, or it won’t be able to download replacement files.

Troubleshooting Common Issues

• USB drive not booting: Make sure the USB drive is properly created and the boot order is correctly configured in the BIOS/UEFI settings. Also, try a different USB port; some ports might not be bootable.
• Startup Repair failing: If Startup Repair fails, try running chkdsk /f /r from the Command Prompt to check for disk errors.
• System Restore failing: If System Restore fails, it could indicate a deeper system issue or corruption of the System Volume Information folder. Try running sfc /scannow before attempting System Restore again.
• DISM failing: Ensure you have an active internet connection when running the DISM command.
• Clean install failing: Ensure your hard drive is properly detected in the BIOS/UEFI settings. If not, check the SATA cables and connections.

Estimated Costs

Repairing Windows 11 from a USB drive can seem daunting, but following these steps, and drawing from my experience, you can often resolve even stubborn boot issues. If all else fails, don’t hesitate to seek professional help.
