In Dual Boot System which understands the Multiple OS and Multiple File System?

A dual boot system allows a single computer to run multiple operating systems (OS) by partitioning the hard drive, enabling users to choose which OS to load at startup. Each OS can manage its own file system (such as NTFS for Windows or ext4 for Linux), allowing for compatibility with different types of files. Bootloaders, like GRUB or Windows Boot Manager, facilitate the selection of the desired OS during boot-up. This setup provides flexibility for users who need to work with different software environments or test applications across various platforms.
