Install Windows 10 on macOS Big Sur- Either it was MacBook or MacBook Pro, most of the Apple systems were based on Intel. With the release of macOS Big Sur, Apple also announced their own silicon-based processor and the discontinuity of Intel processor in near future. While on other hand, there are users who want to install Windows 10 on their Intel-based Mac. So, here will install Windows 10 on macOS Big Sur using Boot Camp.

We are using Boot Camp, as with Boot Camp thing gets easier.

Requirements to install Windows 10 on mac

Before you start the installation, make sure you have the thing given below.

You will need to have access to all basic computer hardware that includes keyboard, mouse…

For RAM, 8 is needed a minimum else 16 GB is way better. As for storage, only Windows OS will take about 64 GB of space, you will need at least 128 GB of storage for Windows OS. If you are dual booting both macOS and Windows OS, then you will need at least 250 GB of free storage.

Using 32-bit Windows OS on Mac is an option due to poor compatibility. You will need to download Windows 10 64-bit in ISO Image. I would recommend you to use Windows 10 Home or Windows Pro for this purpose.

In short, Windows 10 is supported on the Mac systems below:

  • MacBook introduced in 2015 or later
  • MacBook Air and Pro introduced in 2012 or later
  • Mac mini introduced in 2012 or later
  • iMac introduced in 2012 or later1
  • iMac Pro (all models)
  • Mac Pro introduced in 2013 or later

Before we start

Before we start the operation make sure to back up all your files. As there is a slight chance that you might lose your data. For backing up your files, you can use the Time Machine feature on your macOS.

Note: Since we are running Boot Camp for the purpose, of earlier systems it will be easy. However, on new Mac, which has an M1 chipset and these chipsets are based on ARM are not quite compatible with Windows 10. So just in case, if you got problems with the OS, then it is probably the new M1 chipset.

Note: Loading will take place. this process will check storage, old-Time Machine snapshots, cached iCloud and will remove them to make space for your OS. if you want to skip the process then you can click on Skip.

Method for 1 internal disk

If you have 1 internal disk then you will need to choose Windows ISO Image, specify partition size and click on Install. Normally 42 GB of Boot Camp is used, 64 GB is a minimum whereas, 128 GB is recommended.

I would recommend you to use the name as Windows OS or Windows 10 partition, whereas for storage at least use 120 GB or more for windows partition.

Note: you can’t resize the disk size later, make sure you have done the partition according to your usage.

Method for multiple internal disk

If you have multiple internal disks, then;

If you select your startup disk: You can create an additional partition for Windows. Specify the partition size by dragging the divider between the macOS and Windows partitions.

If you select an APFS-formatted disk: You can either create an additional partition on the disk for Windows or erase the entire disk and create a partition for Windows. However, if you choose to create an additional partition, specify the partition size by dragging the divider between the macOS and Windows partitions.

If you select a non-APFS-formatted disk: You can erase the entire disk and create a partition for Windows.

Check secure boot settings

The secure boot by default is Full Security. You will need to make sure, it is not in Full Security before you install Windows 10 on your Mac. You will need to change the Full Security to No Security since we are going to install Windows on it and Full Security won’t let us perform the installation.

One more thing that you will need to change will be the External Boot option. Change it Allow booting from external media.

Now that you have created the partition and loading is completed, the system will restart. On restarting, your Mac will load Windows 10 setup file. From now on, you will need to install Windows 10.

Common Issues Experienced on Windows 10 on Mac

Here are some of the most common issues that a user could experience after installing Windows 10 on macOS.

The startup disk does not have enough space:

This error is when you don’t have enough space. The Windows alone takes almost 41 GB of storage, if you got this error then you will need to add a new SSD.

Your disk could not be partitioned:

your disk cant be partitioned

For this error, you will need to format your disk to MS-DOS (FAT). Since in macOS all the disks are formatted as HFS+ or APFS. Go change the format of windows disk to FAT.

An error occurred while copying Windows 10 installation files:

Normally you will experience this error when your ISO Image of Windows 10 is corrupted or is missing important files. The same error can occur when the ISO is larger than 5GB whereas, the FAT can hold only 4GB. Here you will need to download the older version of Windows 10 and upgrade it later.
