How To Install Windows 8.1 On Mac Without Boot Camp

Mac users have a couple of options when it comes to installing and running Windows on Mac. One can install Windows 8.1 on Mac with the help of Boot Camp software, use virtualization software like VirtualBox to install Windows 8.1 inside Mac, or manually create a new partition and then install Windows 8.1 without the help of Boot Camp.

In one of our previous articles, we discussed about installing Windows 8.1 on Mac with the help of Apple’s Boot Camp software. In this guide, we’re going to show you how to install Windows 8.1 on Mac without Boot Camp software. This method involves creating a new partition for Windows, preparing a bootable Windows 8.1 USB, and of course, installing Windows 8.1 on your Mac.

Complete the given below instructions to successfully install Windows 8.1 on your Mac without Boot Camp software.

Step 1: Turn on your Mac machine and boot into Mac OS X. Open Launchpad, click Other, and then click Disk Utility to open the same.

Step 3: Next, click on the small “+” sign to create a new partition.

Step 4: Select the newly created partition, enter a name for your new partition (remember the name as you can easily select the newly created partition later while installing Windows), select the size (at least 20 GB), and then select the format as DOS (FAT) or ExFAT. You can select either DOS or ExFat here, as you can format the partition with NTFS while installing Windows.

Step 5: Next, you need to prepare bootable Windows 8.1 installation media. We advise you follow our how to create bootable Windows 8.1 USB on Mac guide to quickly create the bootable installation media and also download important support software from Apple. And if you already have the bootable media, you can proceed to the next step.

Step 6: Once you have the bootable media, restart your Mac, hold down the Alt (Option) key while restarting the Mac, choose the option titled Windows (don’t select EFI unless you are very sure) to begin installing Windows on your Mac.

Step 7: Follow the simple on-screen instructions, and when you see the partition selection screen, select the newly created partition (be sure to select the right partition), click Format to format the partition with NTFS, select the formatted partition, and then click Install button to continue installing Windows on your Mac.

Note that during the installation, your system will be rebooted a couple of times. Every time your system reboots, hold down the Alt (Option) key, and then select Windows to continue the installation.

Step 8: From here on, you need to follow the normal Windows 8.1 installation procedure.

Step 9: Once Windows is installed on your Mac, Boot Camp setup will automatically launch. Click Next button, accept license agreement, and then click Next button again to begin installing support drivers. Once done, you’ll be asked to reboot your system to complete the installation. That’s it! Enjoy Windows 8.1 on your Mac.

If you plan to use Windows as your default operating system, we suggest you set Windows as default OS in boot selection screen to avoid pressing the Alt key every time you turn on your Mac. How to quickly reboot into Mac from Windows guide might also interest you.

    @ Vern
    Did you follow the Step 9 in our guide? Have you installed all necessary Boot camp drivers after installing Windows on Mac?

    Can you install Windows 8.1, whilst completely wiping out the OS X partition?

    If I ever need to install Mac, simply run Internet recovery. But space on the SSD drive is precious. I plan on run Mac on the Windows side as a VM. Completely backwards I know, but is what I was thinking.

    This was amazing. I can’t tell you how much of an absolute disaster this process has been. How many times I’ve accidentally wiped my hard drive trying to follow directions from different websites for installs via the command line. How many DVDs I went through. How many hours searching online.

    I started trying to get this to work back in September, gave up and moved on to updating to Yosemite and setting up OS X Server. Now that all that’s done and good to go for all my devices, I thought I’d return to this …

    Your instructions worked perfectly. I don’t understand what was different this time as opposed to before, but I was able to format the drive within the Windows install process just fine. Before, it wouldn’t even let me do that (which is how I ended up braving a few different sets of instructions for command line installs).

    At any rate, thank you, thank you, thank you!

    Hi,

    If you install manually will this enable Virtualisation on the CPU without having to cold boot into Mac OSX then restart into Windows?

    Thanks

    You can change from gpt to Mbr, by clicking on options before, in Disk utility (for the selected partition )

    It keeps repeating that it couldn’t create a partition after i formated it. So it can’t install on this disk. I can’t use bootcamp because my Mac is too old. What can i do ?
