How to Install Windows 10 on Mac Without Bootcamp

There are many options when it comes to installing and running Windows 10 on a Mac computer. One of the most popular options is to use Mac OS built-in Boot Camp Assistant software.

But unlike the other apps that come with Mac OS, Boot Camp has a couple of drawbacks regarding its performance and functionality. Such as,

  • It currently supports only a single partition drive.
  • Often gives unknown error messages with minimal information.
  • Every time it launches, it will automatically download 1.6 GB windows drivers. And it is placed under “/Library/Application Support/BootCamp/WindowsSupport.dmg”.

So in this article, we will teach you how to install windows 10 on Mac OS without using a Boot Camp.

(* Before Step 10 it is crucial to disconnect all the external drives which are connected to the machine. Unplug everything except your keyboard. Also if you have multiple drives connected, disconnect them all except the one which you want to install the Windows 10)

  1. 2020 version of Windows 10 ISO downloaded from microsoft:
    Step 11 was never presented. I was able to complete step 10.
    When I install Windows 10 I get the following error:
    windows cannot open the required file c:\sources\install.wim. Make sure all files required for installation are available, and restart the installation. error code: 0x8007000d

    I did a little research on the error. I found that the install.wim may be larger than 4GB. If the file is larger than 4GB it will exceed the FAT32 format capablities. Any help is apperciated.

    • I formatted the USB-stick as ExFat, as it can handle larger files than the FAT16-format.
      I’m having trouble right now that the windows 10 installation won’t see my hard drives. Working on it 😉
