# VZBootLoader

The base class that defines the management of the initial process of the guest system.

## Declaration

```swift
class VZBootLoader
```

## Overview

Overview The VZBootLoader abstract class defines the common behaviors for booting a guest operating system into a VM. Don’t create instances of this class directly. Instead, instantiate the subclass that corresponds to the type of operating system you plan to load. For example, to create a boot loader object for a Linux kernel, create a VZLinuxBootLoader object; to create a boot loader object for installation using an ISO image create a VZEFIBootLoader. For a macOS system create VZMacOSBootLoader.
