grub-install

Later install Windows, which would overwrite boot manager. When you install Windows after Linux, Windows ignores Linux, doesn’t know how to resize its partitions, and overwrites the Linux boot loader with its own. The grub-install with the device name of the hard-disk re-installs the Linux boot manager. Put an entry of the Windows system. When the PC starts, the user can choose the operating system to boot.

Recommendation – Install Linux after Windows as the Linux installer knows how to deal with Windows, resize its partition, and set up a boot loader with an option allowing you to choose Windows at boot time.

For installations, mostly USB-drive recommended. The user downloads the Linux distribution and creates live media using the burn process. Reboot the PC with this media and start Linux. Create a separate drive or free space for Windows.
