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. In the Installation Assistant window that appears, select the central option labelled Install Windows or another OS from a DVD or image file and click Continue. 3: Install the Guest Additions You should consider installing. 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). Your host machine should have at least 1 GB of RAM and plenty of CPUs remaining so the host OS and VirtualBox can function smoothly. 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 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. You should see two entries in a list (they are cryptic looking PCI bus paths). If you can no longer connect, check whether you need to update the Guest IP. This is especially true if the Mac isn’t the only virtual machine you run. Note: It’s possible the Guest IP will change from time to time. Next you’ll be asked to name the VM and select which type it is from the drop-down menus. To create a new Virtual Machine you’ll first need to click on the New icon in the top left corner of the window. Select Boot Maintenance Manager and click. For Guest IP, go to your Mac, use Windows-Space to search for Network Utility, and type in the IP that appears there. Launch Virtualbox and you’ll be presented with a mostly empty menu welcoming you to the software. You’ll be brought into an EFI text-mode GUI. I was able to fix the UEFI problems as follows ( credit to techrechard website):
