But that's only the start of the story. After installing Windows, you need to install all needed drivers and utility programs from the manufacturers site in the right sequence. It's much easier to reinstall the factory image from the recovery partition on the hard disk (if there is such a partition, better check the user manual) or to order the recovery media from the manufacturer.
The device to boot from is defined in the BIOS setup. How to go into the BIOS setup is dependent on the BIOS (on my MSI motherboard it's F2); you might need to check the user manual for this also.
An alternative can be to to boot into the boot device selection menu by pressing the right key at the right moment (on my MSI motherboard it's F11).
