Problem with VirtualBox 5.x running on GNU/Linux Debian 9.x host:
EFI-enabled guest suddenly boots only into UEFI Interactive Shell.
It waits for 5 seconds and then it drops to Shell>.
I don't remember any modifications, which I would have done, neither to the host, nor guest, or VirtualBox itself.

Plausible fix:
In UEFI Interactive Shell, enter the file system:
fs0:
Following up with creating this file:
edit startup.nsh
Enter this or similar line to it:
EFIdebiangrubx64.efi
Press CTRL+S to save the file.
Press ENTER to confirm the file name.
Press CTRL+Q to exit the editor.
Restart the Guest:
reset
Important notes:
For some reason you have only a few seconds to edit and save the file. If it takes you longer, then the guest may react with a significant delay. Or it may even freeze.
Replace
debianwith your system's id, e.g.ubuntu. You may verify this by simply going into theEFIdirectory and runningls.
Another way:
If you don't succeed, and supposing your guest is Linux type, I myself had to do it:
Boot from live USB with any Linux.
Mount the root file system.
Create this file on the mounted file system, adjust the path to wherever you have mounted it:
/boot/efi/startup.nsh
Enter the above explained line to it.

Workaround:
In the VirtualBox settings for your VM, go to System settings and in the Motherboard section un-check the
Enable EFI (Special OSes only).
Save the settings and restart your VM.
Important notes:
This will make the guest system run on BIOS / MBR legacy boot.
Only use, if the solution above does not work for you.

Yes, thank you! It was necessary to Enable EFI in order to make the GParted Live CD work. However, after resizing the disk partitions in GParted, I encountered this error, and also an error "fs0 is not a correct mapping" if I tried to enter the file system. Disabling this flag solved issue.

I had this come-up today. In my case, I had selected "Enable EFI" on the Settings: System panel, on the Motherboard tab. That was conscious because the drive I wanted to boot from wasn't (booting).
This can be removed by unchecking the check-box.
While it looks useful, it is very frustrating so I advise people to open a web page with the help outpur on show. All the commands scroll off the screen before you have a chance to read them. And there is no less or more command.
