how to make a window bootable disk from normal disk?

[Fli]

Use some bootable medium (CD, DVD, USB stick) equiped with operating system installation.

Example Windows installation CD, USB stick made to allow Linux installation.

I like the USB stick way as you can reuse the stick when needed. Here is how to do it: https://unetbootin.github.io/
