### Getting to the boot screen
Just after you power on your machine, make the Qubes OS medium available to the
computer by inserting your DVD or USB drive. Shortly after the Power-on
self-test (POST) is completed, you should be greeted with the Qubes OS boot
screen.
Booting is the process of starting your computer. In this case instead of
booting the computer normally, we'll want to tell it to boot from the USB
drive to which you just burned the Qubes installer. So just plug the USB
drive into a USB port and follow the next steps.
Then you'll need to power on the computer and immediately press a specific key to
enter a special menu of your computer called the "BIOS" or "UEFI"
(depending on your computer model).
The key to press varies from brand to brand. `Esc`, `Del` and `F10` are
common ones. If you're not sure about the key to press you'll have to view in the
machine's user guide or serch the web for `accessing BIOS/UEFI <COMPUTER_MODEL>`
(replacing with your specific computer model).
The menu will look something like this:
| BIOS (older systems) | UEFI (modern systems) |
|----------------------|-----------------------|
| ![picture of BIOS image of Thinkpad T430](/attachment/doc/Thinkpad-t430-bios-main.jpg) | ![UEFI menu picure](/attachment/doc/uefi.jpeg)|
Within this you'll have to navigate to the boot menu. It can be of two types:
* (a) **a list of devices to boot (starting) from** - in this case you select your USB drive (if you have multiple USB-looking devices, try them all until one works)
* (b) **a list of devices in order** - here you order the boot devices in such a way that the USB drive is the first one.
Then save the configurations and restart your computer. If you're successful in this step after a few seconds you'll be presented with the installer screen:

After the POST, you may have a chance to choose a boot device. You may wish to
select the USB drive or DVD drive as a temporary boot option so that the next
time you boot, your internal storage device will be selected first.
