The tutorial is based on one way (among others) to install and service Grub4EFI (G4E).

This way of installing worked for me, even on VirtualBox - the default way may differ from this.

Try this process on a testing-computer first - if errors occure your system may fail to start.


Install Grub4EFI


Download and extract G4E-Installer.
Mount extracted ISO to drive letter.
Here Y:
Start G4E_Menu.exe as administrator.

If provided, at least 2 files should be listed as existing.
