The last step is to reset the VM via OVMF, after that it should boot using the just configured boot entry. Press enter again and commit your changes: Press enter, select the boot entry with the arrow keys and move it up and down with '+' and '-' respectively.

To make it the default boot entry, you now have to change the boot order: Navigate the folder structure to your bootloader (EFI/debian/shim圆4.efi in this example) To add an entry of an existing bootloader go into the OVMF Menu by pressing 'ESC' during boot.
#HOW TO USE VIRTUALBOX EFI PC#
For these reasons, Microsoft has made UEFI support mandatory for PC manufacturers since Windows 8. It also makes Secure Boot possible, lessening the risk of the firmware being corrupted or taken over by malware. EFI allows for much larger boot partition sizes than BIOS. Why was this done? Given that BIOS has been around so long, its limitations have long been apparent once PCs got more powerful. It's intended to replace the old BIOS system that has existed since the original IBM PC was created in 1981. But first, let's find out what EFI really is.ĮFI, also known as UEFI, stands for Extensible Firmware Interface. Here's how you can easily set up an EFI-based Linux virtual machine on VirtualBox. It's easy to use the new standard to set up Linux virtual machines, even if it is officially experimental. While BIOS-based machines are the standard for VirtualBox, in the real hardware world, almost all new PCs use EFI firmware. To use EFI for a given virtual machine, you can enable EFI in the machine’s Settings dialog (see chapter3.4.1,Moth-erboard tab, page48).
#HOW TO USE VIRTUALBOX EFI MAC#
If you have a recovery partition, to boot directly into the Recovery Mode turn on the Mac and immediately press and hold (⌘)-R The ambiguity of that last statement is I did that awhile before writing this comment and I don’t recall what I booted into first, only that it worked and was not hard to figure out what to do at that point. Installation will continue, or you will boot into the OS or get the Recovery Utilities menu (where macOS can be reinstalled from or Disk Utilities run).

If the recovery partition isn’t present and valid, these instructions won’t work. If the 2nd partition isn’t the recovery partition, look under the paths in the list to see if one of them is it. The second PCI path is probably to the recovery partition, the one you need to boot from. The first PCI path in the list is probably the boot partition that doesn’t contain bootable firmware. Select Boot Maintenance Manager and click.

You’ll be brought into an EFI text-mode GUI. I was able to fix the UEFI problems as follows (credit to techrechard website): The ambiguity of that last statement is I did that awhile before writing this comment and I don't recall what I booted into first, only that it worked and was not hard to figure out what to do at that point. If the recovery partition isn't present and valid, these instructions won't work.Ĭlick the 2nd entry, you should see (and then click): If the 2nd partition isn't the recovery partition, look under the paths in the list to see if one of them is it. The first PCI path in the list is probably the boot partition that doesn't contain bootable firmware. You should see two entries in a list (they are cryptic looking PCI bus paths). Seach for grub2-install and parameters -boot-directory and -efi-directory (in case you want UEFI booting). You'll be brought into an EFI text-mode GUI. Just use a small 8MiB (also a 2Mib can be enought) with Grub2 and put on grub.cfg a menu to load OS from USB drive, all drives (fixed, internal, external, usb are seen by Grub2 in the same way).
