Hi, I'm looking for information about UEFI in windows 10 . I installed rEFInd for ubuntu boot too, but I didn't have to configure it right because I had to format GPT disk to create EFI partition ,System reserved partition ; to be able to boot windows again. Now in the BIOS boot menu both windows entry and ubuntu appear.

I'm seeing a series of statements, but I'm not understanding what the question is?

The VirtualBox VM settings includes an EFI option. This is known to work with Windows guests and GPT partitions. I've used it myself with a Debian VM as well.

I can't see much point in installing a multi-boot manager in a VM. It seems simpler just to have several VMs. Unless the goal is to test the boot manager?
