Disabling System Integrity Protection from guest El Capitan under VirtualBox 5
One well known issue of running a guest MacOS X under VirtualBox is that it'snot possible to enter Recovery OS by pressing the Command+R key combination onVM startup. In fact after reading some bug reports on VirtualBox bugtracker itseems that it's not possible to enter Recovery OS at all.

You can do soft restarts, but if you'll shutdown the VM and boot it up again, you will need to disable SIP again.

You will be greeted with an old school text mode BIOS interface, in which youshould choose the Boot Manager option.

After getting the command prompt, switch to the FS2: drive:
