System info:
Steps to reproduce:Virtualbox Version 6.1.26 r145957 (Qt5.15.2)
Debian Bullseye
Installed from oracle repository
Intel i7 10th gen
- Install a guest linux vm, set EFI option on in settings.
- In linux vm set EFI boot option using efibootmgr -c. It creates a new option and makes it top.
- List using efibootmgr.
- Reboot
- When virtualbox screen is shown press F12 to select boot menu.
Obtained result: It boot straight into the OS.
I guess it is a bug in EFI implementation.
