 ===== FAQ =====
-** Why are we doing it? ** \\
+==== 1. Why are we doing it? ====
 The computers of the students with their operating systems (OS) are usually very heterogeneous. Some students use Windows with different versions, licenses and language options, others use Mac and a few Linux. Throughout the last semesters we spent a considerable amount of time fixing annoying problems related to different software installations. As a consequence for this semester (SS2020) we will try for the first time to use virtual machines running on your operating systems.

-** What is a Virtual Machine? ** \\
+==== 2. What is a Virtual Machine? ====
 To put it very simply: A Virtual machine (VM) is a virtual 'computer' running in a window of the host computer. Example: Ubuntu Linux VM running on a Windows 10 host operating system or Debian Linux VM running on Mac OS, etc.
-** Which VM are we using? ** \\
+==== 3. Which VM are we using? ====
 We will set up a Linux VM with Ubuntu 18.04 LTS. It is a wide spread open source OS, very stable, clearly manageable, well supported and extremely transparent.
 :!: We prepared our own Linux VM image with the most important **software components for AMC and SciProg pre-installed**! Everything needed is in already in the VM!
-** What is needed? ** \\
+==== 4. What is needed? ====
 On your computers you have to install VirtualBox from Oracle for your particular operating system. VirtualBox is available for Windows, Mac OS, and Linux. Yes, you can run a virtual Linux machine even on a Linux machine. You should do it to acquire the same state of software installation in the VM!

+Problem: \\
+When you start VirtualBox on a Windows host sometimes the following error message comes up:
