If you are facing Flyby11 not working, Tiny11 Builder can be an alternative way to create a lightweight installation image by removing unnecessary components and reducing system requirements for older computers.
How to use:
- Download Tiny11 Builder and prepare the official ISO file.
- Run the script with administrator privileges.
- Select the ISO source and wait for the customized image to be created.
- Use the new image to perform a clean installation.
If you find Flyby11 not working during the upgrade process, creating a customized installation image can be another option to try when dealing with compatibility limitations.
Disadvantages:
- Requires some technical knowledge to use correctly.
- The process may take some time depending on your computer.
- Removing system components may affect some built-in features.
Note:
- Always keep a backup of important files before installation.
- Use the original ISO source to avoid unknown modifications.
- Test the customized system carefully after installation.
