I had problems with os-prober not finding fedora installations and have a script that "may" be useful. Very little checking has been included - ie "is it being run as root" Hopefully the comments explain what it does! It can be used on any partition that has a fedora "root" installation, including the currently booted / device. AFAIK it can do no damage as it only copies files and creates directories and files that did not exist before. It helped me learn about BLS
