I found this amazing guide for it (), but it was for Windows so I had to adapt it. Here is how I did it for anyone else who has this problem. So, I needed to use FAT32 for my BIOS to accept it, but both the April 2018 and October 2018 updates had an install.wim file that was over 4 GB (I downloaded the English international version for both, maybe other versions are different?). The WIM is read-only (file permissions, header flag, or split WIM).Ĭp install.wim /Volumes/MYUSB/sources/install.wim You may need sudo, because you could encounter an error like this: Can't modify "/home/roger/win/sources/install.wim": Permission denied "install.wim" optimized size: 3311533 KiB Wimlib-imagex optimize install.wim -solid "install.wim" original size: 4463411 KiBĪrchiving file data: 9 GiB of 9 GiB (100%) done
I managed to reduce the size bellow 4Go, my FAT32 usb thumb accepted it, and booted with successĬopie the bigfile from the iso volume to your HD Disk (Download example by example)Ĭp /Volumes/CCC./sources/install.wim install.wim This can now be used as a bootable drive.The open-source package called wimlib, can also "optimize" a wim file. Once the command has finished and your files have been moved over to the USB drive, you will need to run the command " hdiutil unmount /Volumes/MOUNTED-ISO", again replacing the word MOUNTED with the correct name.Ĭlose the terminal and eject your USB drive. Next, run the command " cp -rp /Volumes/MOUNTED-ISO/* /Volumes/WINDOWS10/" where you can replace MOUNTED with the name of your mounted ISO.
It will be similar to /Volumes/MOUNTED-NAME. Note the name of the mounted iso, which can be found by looking at the terminal. iso image by using the command " hdiutil mount ~/Downloads/WINDOWS10IMAGE.iso" where you can replace the "WINDOWS10IMAGE with the name of your downloaded file.
Run the command " diskutil eraseDisk MS-DOS "WINDOWS10" GPT disk3" without the quotation marks and you can replace the "3" at the end with the correct number.ĭownload the iso file for Windows 10 and save it in the Downloads folder if it hasn’t been saved there already. Identify your USB drive and note down the name, such as disk3. Type "diskutil list" and hit the enter/return key to see a list of all connected drives.
Again, you will need a USB drive.Ĭonnect your USB drive to the Mac and then launch Terminal. The Terminal app is more complicated to use than other methods however it does not require you to use a third-party application in order to create a Windows 10 bootable USB drive. This will have created a Windows 10 bootable USB using a Mac that can now be used on your PC. You can now quit Bootcamp and then Eject the USB to safely remove it. Once the process has been completed by the Bootcamp Assistant, the USB will have been renamed. Keep this in a location that is easily found (such as the Downloads folder).īootcamp will locate the downloaded iso file automatically however if it is not found, you can use the "choose" button to locate it manually.Ĭlick on Continue and wait until the USB is formatted and set up to become a bootable drive. iso file from the Microsoft website or another reliable site. Then click on continue.ĭownload a Windows 10.
Tick the box for "create a Windows 7 or later version install disk" and uncheck the "Install Windows 7 or later version" option. Please note that Boot Camp is not supported in macOS Mojave and later. In order to create a bootable USB using Boot Camp, you will require a USB that has 16GB of storage, or more.
