So I have spent the past couple of days attempting to install Windows 8.1 onto a MBP with High Sierra. Apparently, this model is unable to create and boot from a USB dive. So the normal Boot Camp method is out of the question.
I've been following a guide posted on this site that uses VirtualBox to install Windows without the need for a USB drive or even a DVD.
Here's the guide for reference: Is it possible to Bootcamp Windows 8.1 using USB on Late 2011 MBP?
So here's what I've done so far...
- Installed the latest version of VirtualBox
- Created a new VM with Windows 8.1 as the version. I did not add a virtual drive.
- Using the Terminal, I found that the internal disk,
disk0, had 4 partitions. I had created a WINDOWS partition, identified as
I entered the following series of commands:
sudo chown $USER /dev/disk0s4 sudo chown $USER /dev/disk0s1 sudo chown $USER /dev/disk0 diskutil unmount /dev/disk0s4 VBoxManage internalcommands createrawvmdk -filename ~/RawWinDisk.vmdk -rawdisk /dev/disk0 -partitions 1,4 diskutil unmount /dev/disk0s4
in a Terminal application window.
- So far so good. No issues here besides having to disable the SIP in order to create the VMDK file.
- Back to the VM I created early, I when to the settings and clicked on the "+" sign by the SATA controller. I added the VMDK file that I just made so it appeared below the SATA controller.
- This is where I had to improvise. The guide asks to click on "Empty" below the IDE controller... except there was not IDE controller listed. Instead, there was another "Empty" shown under the SATA controller. So, I added a virtual disk (The Windows 8.1 ISO file) and checked in the "Live CD/DVD" option.
- And here is where everything goes kaputs. I go to start the VM. The Windows 8 installer boots up fine. I enter in the product key and continue. I am given the option to upgrade or do a clean install. I choose clean. The installation halts with the following error:
Compatibility report: The computer started using the windows installation media. Remove the installation media and restart your computer so that windows starts normally. Then, insert the installation media and restart the upgrade. (Do not select Icustom [advanced] to perform an upgrade Icustom [advanced] installs a new copy of windows and deletes your programs and settings.)
So now what? I know the ISO file is fine because I have used it before to reinstall Windows. Is there a setting I missed?
