I have flashed twice the kali installer iso, because it did not work by itself. What can I do to install that O.S. ?

Hello, if you flashed the .iso to a USB flash drive or a DVD, you will want to boot the computer using that media. You may need to adjust your computer’s BIOS or boot settings (often by hitting F2 or DEL at startup) to allow booting from the USB/DVD. Note that installing the OS will overwrite anything currently on the computer’s hard drive! Let us know if you need any further assistance installing your OS.
