Unfortunately, that tool re-formats the USB flash drive as NTFS. Note: The Microsoft website has a Windows USB/DVD Download Tool which can do what WinToFlash does. Go ahead and uninstall this unnecessary browser plugin using the Control Panel’s “Uninstall a program” function.

Unfortunately, the first time you run the latest version of WinToFlash, it will install a browser plugin called “WinToFlash Suggestor” which adds advertisements to search suggestions. So make sure to use an 8GB USB flash drive or larger. I tried a 1GB USB flash drive and WinToFlash completed successfully. Note: Strangely, WinToFlash won’t throw an error even if you use a USB flash drive that is too small. WinToFlash will re-format the USB flash drive using FAT32 format before copying the content over.

I used the free Novicorp WinToFlash Lite utility to copy the contents of my Windows 8.1 with Update ISO file (alternatively, you can use a Windows 8.1 DVD) to the USB flash drive. Update: Instead of using the WinToFlash utility below and dealing with its browser plugin spam, use Window’s built-in DiskPart command-line utility to create a bootable USB flash drive containing the Windows Setup. (2015 Macbooks only support 64-bit Windows 8 or later.) Because Windows 8.1 setup requires 4.5GB of space, you must use an 8GB or larger USB flash drive I ended up using a spare 16GB flash drive that I had. I used my Windows 7 desktop to create a USB flash drive containing the 64-bit version of Windows 8.1 with Update. I’ve documented the steps I took below.Ĭreate a Windows 8.1 Install USB Flash Drive

It turned out that for newer Macbooks, I must download the Boot Camp Support Software using the Boot Camp Assistant.Īfter I overcame the above and other issues, I was able to get a Windows 8.1 Boot Camp working. I inserted a second USB flash drive containing the latest Boot Camp Support Software I had manually downloaded from the Apple website, but Boot Camp Assistant still complained that it couldn’t be found. After that, the Boot Camp Assistant asked me for the Boot Camp Support Software (Windows drivers).

I managed to create and insert a USB flash drive containing the latest Windows 8.1 with Update. I attempted to install Windows 7 using the Boot Camp Assistant, which immediately asked for a Windows 8 or later installation media to be inserted. I recently upgraded to a 2015 Macbook Pro Retina 13 inch laptop.
