   Hello!   
      
   I want to install Slackware 15 64 in VBox in EFI mode.   
   Installation was possible, but the VBox EFI won't boot the installed   
   grub, but the grub from the install image. From that I can use "Detect   
   installed OS" to start the installed GRUB and then boot the installed   
   OS.   
      
   After installation, I chrooted to /mnt and ran   
      
   grub-install   
   grub-mkconfig -o /boot/grub/grub.cfg

   The grub executable exists, although VirtualBox complains it can't find it.   
   If I want to select "boot from file", it shows an empty page, so I assume it   
   doesn't even detect the EFI partition. It is usable when the ISO is inserted   
   and shows the content of its EFI folder.   
      
   Does anybody have an idea what is going wrong and if that is an issue in   
   VirtualBox or in Slackware/GRUB?   
      
   --    
   kind regards
