Answer 1

Assuming you want to install it in dual boot, read this: https://askubuntu.com/questions/6317/how-can-i-install-windows-after-ive-installed-ubuntu

If you want to remove Ubuntu and replace it with Windows, insert a windows disk and install Windows or do this by making a flash drive into a bootable drive that has the windows ISO on it.

Answer 2

If you want to just run a program, that is only available on windows, on Ubuntu, you can try wine. You can also use a virtual machine like the oracle virtualbox, to install windows (or any other os) on your linux distro. It is also possible to install windows next to Ubuntu, witch is (I think) sadly only possible if you installed windows first and then Ubuntu.

Make bootable pendrive for Windows n install. If you want to use Linux, you can use either virtual machine or dual boot mode for this you need seprate partition in c drive. You will get steps on YouTube.
