Follow the onscreen instructions to install Boot Camp and Windows support software drivers. You will be asked to restart when done. For example, if your Mac has GB of memory, its startup disk must have at least GB of storage space available for Windows.
To see how much storage space is available, click the Storage tab in the same window. These Mac models were offered with GB hard drives as an option. Ken Thompson has an automobile which he helped design. Unlike most automobiles, it has neither speedometer, nor gas gauge, nor any of the numerous idiot lights which plague the modern driver. I recently managed to install a current Windows 10 distribution onto an older iMac that I had in storage.
I wanted to set up this machine to run some specific Windows software for which it was well suited, and that let me make good use of an otherwise idle machine. The iMac has a then-fastest-around 2.
Each of these issues represents some hours of repeated head-banging attempts to get past it that I hope to save you, dear reader, from repeating. I am assuming in the below that you know how to do a Windows installation using Bootcamp or are prepared to work that out elsewhere. Each item below starts with a headline that frames the fix — so if you mostly just want to get it done — just dance across those headlines for a fast path to a working result.
Ok, annoying but straightforward. Cue the download and install process, and come back in several hours…. Beats me! Yay — that suggests the bug has been sorted out — after all, it mentions Windows 10! Next step is, thus, a Mac OS update pass to move up to the very latest Mojave build, including a version of Bootcamp with the issue resolved in it. This is in fact documented on the Apple support site if you own hindsight. After Bootcamp managed to set up my USB stick properly, and managed to download and copy on the Bootcamp windows drivers in as well, it then failed to partition the drive successfully the last step before it triggers the Windows installation to commence.
Your disk could not be partitioned ; An error occurred while partitioning the disk. Please run Disk Utility to check and fix the error. The problem here is that I did run Disk Utility to check and fix the error, and no error was fixed! Time to dive deeper — open up the display of detailed information the little triangle that can be used to pop a window of debug text during the underlying fsck….
Disk Utility can even partition the drive just fine — but the Partition function in Bootcamp itself … fails. The fix turns out to be annoyingly radical: Do a full system backup, and then do a full system restore. Use Time Machine to back up the whole machine to that local storage, then boot in recovery mode and restore the system from that drive again.
However — it helped! When I tried yet once more, after this radical step… now the Bootcamp partition step works — hazzah! Once windows starts to install process, it reaches a point where it displays all drive partitions and asks you to just pick the one to install Windows onto. It fails, saying the partition is in the wrong format. It seems that some inexplicable reason Bootcamp has left the intended Windows partition in the wrong state as far as the Windows installer is concerned.
Then you can re-select it — and the installation now starts to work — yay! Meantime I just switched to a wired keyboard — ironically the one I found in my storage room was a genuine Microsoft branded one with lots of useful extra function keys on it. This is important for all sorts of reasons including WiFi not working until you do.
After everything else and one and a half days of this stuff — this was really frustrating. It appears to the the case that the wrong version of a crucial driver file keyboard support related, by the looks of it is loaded in by Bootcamp, but when installing onto this particular generation of iMacs. The fix — after I found it — involves booting Windows in diagnostic mode and disabling that driver file. You then wind up with the opportunity, during the reboot, to access diagnostic functions.
SYS as per this screen shot:. The recent switch to the Windows OS on the Mac could disrupt the performance of the driver, and you would have to download and install the latest Realtek Driver on your Mac.
It once was a big selling feature for converting users who came from Windows. One of the errors is the 'Boot Camp installation failed' error. Apple suggests that you move to macOS Mojave and try installing Windows 10 again, but the issue doesn't always go away.
Another common error is when trying to copy the Windows installation files. In still other cases, you'll notice that several Mac features don't work when running Windows, such as Apple Software Update stopping, no audio from built-in speakers, mic or webcam not recognized by Windows and so on. To avoid such errors and issues, which can often take quite a lot of your time to figure out and fix, you can use alternative solutions to install Windows on a Mac from USB. Though you will still need to use Boot Camp Assistant for part of the process, but you're not likely to come across major installation errors when doing this.
You can also use Terminal in Mac to help you install Windows. The next two sections describe these methods in detail. In case it does not work, we will suggest two alternative software in this section. You can easily fetch all the required drivers using Bootcamp, but the installation process for putting Windows on your Mac is different from how Bootcamp does it. It can do a lot more than just create bootable media, such as creating ISO files, editing them, copying from disc to ISO and so on.
For this process, you will need to use the Burn module, which is explained below:. When the dialog appears, click Save and specify a location for the files. Step 3 : Open the UUbytes program and click on the module that says Burn.
Select the ISO image and click on Burn. This will create a bootable USB drive for the Windows installation. It is simple to use and has less errors. This method uses Terminal application to create the bootable media for Windows You will still need Boot Camp Assistant for the support software, but if you're comfortable with command line work, you try this approach. You will first need to download the Windows 10 ISO file.
You will also need to use Boot Camp Assistant to get the support files, for which you can follow Step 3 from Method 1. Step 1 : Launch an instance of Terminal. Type the following command and then Enter to list out your drives:. You will be using this in the next command. For now, let's call it disk2. The next step is to format your USB drive for Windows Use the following command, then hit Enter:.
Step 3 : You will be able to see a mounted disk called Windows You can also run the following command:. Step 4 : Unfortunately, there's no progress bar to indicate that the bootable media is being created.
However, after a sufficient amount of time has passed, the USB drive will contain bootable media for a Windows 10 installation. This can be done with the help of built-in Disk Utility app. However, this is a highly risky task. Please backup your important data to iCloud or external drive with Time Machine. Click the internal disk name on the left sidebar.
Now, click the Partition tab on top menu. At the end, set a size for the new partition. Finally, click Apply button to take this into effect. Mac will boot from internal hard drive or SSD in default.
