What happened?

Hello!

Creating a snapshot of an EFI guest OS deletes the UEFI boot manager entries. After that the OS needs to be manually booted from the EFI file and the UEFI boot manager entry needs to be added by the guest OS again (e.g. using grub-install or efibootmgr).

I am using VBox 7.2.16-dfsg-1

How can we reproduce this?

Create an EFI guest OS, install it. The boot manager entries are there.
Now create a snapshot of the OS and try to boot it - it will fail as the UEFI boot manager entry is missing.
