rEFInd - Boot Manager alternatives
rEFInd - Boot Manager is a free and open-source utility that displays a menu of boot options during computer startup. It allows users to select from multiple operating systems installed on a system utilizing the Extensible Firmware Interface (EFI) or Unified EFI (UEFI) standards. Originally derived from a previous boot manager project, it offers enhanced control and the ability to list a greater number of available operating systems than its predecessor.
