Solution

Go to SDK Manager and check at the very bottom if you have installed "Intel X86 Emulator Accelerator (HAXM Installer)". Install it if you don't have it.

Take into account that you'll need to run the downloaded file since it's an installator. If you mouse over the row on SDK Manager you'll be able to see the intallation path.
