### Installing the Predator-OS Linux on a real computer
#### Boot from USB flash drive
Insert the USB flash drive into the laptop or PC you want to use to install Debian stable and boot or restart the device**.** It should recognise the installation media automatically**.** If not try holding F12 during startup and selecting the USB device from the system**-**specific boot menu**.**
F12 is the most common key for bringing up your system**’**s boot menu**,** but Escape**,** F2 and F10 are common alternatives**.** If you**’**re unsure**,** look for a brief message when your system starts – this will often inform you of which key to press to bring up the boot menu**.** You should now see the welcome screen inviting you to either try or install Debian stable**.**

Click Restart Now**.**
When you restart**,** you will be prompted to remove your USB flash drive from the device**.** Once you**’**ve done this press ENTER**.**
Enter your password on the login screen **(**assuming you selected that option when creating your login details**).**
The user that has already been created can then log in and begin working immediately**.**
