You have downloaded the Windows installation ISO and created a Windows installation USB disk or simply want to use Live CD. So you want to boot your computer from your USB device or CD/DVD now?
This tutorial tells you how to start your computer on USB disk in order to start the installation of Windows or your Live CD. There is a jargon called “booting” on a USB device.
Every computer comes with BIOS, which performs hardware checks when turning on the computer. The BIOS tries to boot an operating system on your different devices (USB device, DVD-ROM, hard drive, etc.).
In general, Windows starts from hard drive. Since BIOS follows a pre-defined order, ie a startup sequence where it will test the devices in order: DVD-ROM, Hard Disk, Network, USB device. This is called “Boot Priority”.
If the hard drive is positioned first and Windows is present, the computer will always boot from the hard drive. In case you want to start on a USB device, you will need to change this order or prompt to boot on the USB device.
The boot menu is a menu that allows you to boot the computer from your choice. Access to the boot menu is available via a key to type on the first boot screen of the computer. This key is different from one constructor to another.
In the table below, the keys by manufacturer are summarized:
|ACER||Del, F2||Esc, F12, F9|
