So you've downloaded the ISO, you've burned it onto some media, and you're ready to boot Parrot on your computer.
In order to do so, simply insert your boot media in the computer and reboot it. Now ensure your BIOS/UEFI is set to boot your removable media first or you'll pass Parrot and go straight to your harddrive.
If everything goes well you will be greeted by the Parrot boot screen and soon on to endless fun.
By USB Drive
If you're using a very old computer you might not be able to boot your system from a USB drive: in this case you will have to use a DVD or another device your computer will recognize as a boot device.
Most laptops allow you to access BIOS/Ueffi screen and/or booting menu pressing F2 or F12; for most desktop computers press F8; for other kind of devices try pressing esc, F12, f11 or F10. Google your manufacturer to find out what makes your system barf up its BIOS.
Boot Menu disabled
For some computers, the booting menu may be disabled by default: you will have to access the BIOS settings and enable it, then reboot the computer and press the right key to access the booting menu.
Boot Menu not available
Some computers allow you to boot the system from USB drives but don't display a menu to select the booting device. If this is your case, you need to access the BIOS settings, go to the booting panel and change the order of booting devices, placing the USB drive on top of the list. Then simply reboot the computer and the BIOS will boot from USB drive.
In case you have a computer with Secure Boot enabled, you will have to access the BIOS settings, disable secure boot and set it to legacy boot. If your computer doesn't provide a booting menu, follow the instructions displayed on this page in the section above (“Boot Menu not available”). If all else fails, google your make and model. Someone who attempted to install Linux might have a solution.
Booting a system from a DVD is much easier and compatible with most machines.
You can boot a DVD by using the standard procedure for the USB drive as described above.
Booting DVD on old MACs
Turn on your computer, insert the DVD straightaway and press the C key as soon as you hear the beep signaling the computer has been turned on. Release the button after a few seconds, as soon as you hear the DVD has started working.
Insert the Parrot boot device during the booting step and press the ALT key: keep it pressed until the booting device menu has been displayed.
What is live mode?
The live mode is a special boot mode offered by many Linux distributions, including Parrot OS, which allows the users to load a fully working Linux environment without installing it.
This is possible because the system is not loaded onto the PC's hard drive, instead it is loaded in RAM (Random Access Memory).
Parrot OS allows you to install the OS while in a live environment, use all the tools and even create a persistent live environment.
To create a live boot device please read this page.
Default username and password
In Parrot OS live environment, the default username is "user" and the default password is "live". (if live does not work, try toor)
