How do you remove fedora os completely?

To completely remove Fedora OS from your system, you need to boot from a live USB or CD of another operating system, such as Windows or another Linux distribution. Once booted, use a disk partitioning tool (like GParted) to delete the Fedora partitions, which typically include the root (/) and swap partitions. After deleting the partitions, you may need to update the bootloader (like GRUB) to remove Fedora from the boot options. Finally, you can proceed to install your desired operating system in the freed space.
