The next time you boot the machine, you can choose between Windows and Linux.
There are alternatives to using a boot manager. You could have two internal disks, use each of them exclusively for one OS, and then select the boot device in the BIOS or UEFI settings or via a hotkey that brings up the computer's built-in boot menu. Using GRUB is more user-friendly than those alternatives, which is why it is the more popular choice.
