Hi guys, I have read this article and your resonses and mightbe able a few with their errors.
It is not important whether you run Lion, Mavericks or Sierra, it will work on all of these systems if you follow the rules (a few of which are not mentioned in the article above)
- Open Termin
- run “diskutil list” (for this example I will assume the disk is disk2 -so please change it to your disk if necessary)
- Open Disk Utility
- Unmount the disk you want to install the system too (important -if you forget this you will get an error and the bootcamp.vmdk is not created — you will get a File Not Found Error if you do not do this)
- go back to Terminal
- run “sudo VBoxManage internalcommands createrawvmdk -filename “bootcamp.vmdk” -rawdisk /dev/disk2" (if you are not usind sudo you might get an error)
- This terminal command will mount the disk again so you need to go back to Disk Utility and unmount it again (You will get an VERR_ACCESS_DENIED error if you do not do this)
- Go back to Terminal and run “sudo /Applications/VirtualBox.app/Contents/MacOS/VirtualBox”
- NOW AND THIS IS IMPORTANT (for all that could not see the disk when they try to boot) In Virtualbox you will have to check the settings according to your Mac. You might want to change to ICH9 but YOU HAVE TO CHECK “Enable EFI” — No EFI and you will not be able to see the disk !!!
- Lead the Windows Disk Image in Virtualbox Settings and run your Virtual Machine
- When it restarts stop your virtual machine and restart your Mac
- You should now see “EFI Boot” — choose it and you are good to go.
