There are actually a few ways you can successfully install Windows on an external drive. It allows you to install Windows on an external drive without first having Windows installed on a PC or in a virtual environment. This is an advanced process with quite a few pitfalls that can trip you up.
Be sure to read through the process before undertaking it. Also, make sure you have a current backup before beginning. Warning : The erase, format, and partitioning process will delete all data currently contained on the external drive.
Do not select the volume located just underneath the device name. Warning : The process of preparing the USB flash drive will delete any data contained on the flash drive. The device will likely have the name of the USB flash drive manufacturer listed. After making your selection, click Continue. Provide your administrator password, and click Continue. You can download the app from the VirtualBox website. You can find the external drive by looking for the name, type, or if this is your only external, by the location [external, physical].
We can do this because in the previous step, we mapped the external drive to a VirtualBox virtualized disk. In order for VirtualBox to be able to access the external drive, we need to launch VirtualBox with elevated permissions. Once again, we turn to Terminal. You may notice the menu is empty or does not contain the virtual disk file we created earlier. Click the folder icon just to the right of the dropdown menu.

This will allow you to browse to the bootcamp. Select the bootcamp. This is usually located in the Storage section of the virtual machine. Because the external hard drive has been assigned to the VirtualBox machine, it is the only drive that will be listed. At this point, the Windows installer has copied all the files to the external drive, and has set up a boot environment that you can start your Mac from.
Next time you boot from the external drive, Windows will complete the installation process.
Use the arrow keys on your keyboard to select the Windows drive. The bootup process can take a while, so be patient. At some point during the installation, Windows will restart your Mac. When it does, your Mac will restart with the normal Mac OS. You need to be present to hold down the Option key and select Windows to start from. Once the installation completes, all your Apple hardware, including wireless keyboards and mice, should be working.
Drive is properly formatted, been trying for 5 hours and im starting to become desperate. Did someone get it to work on a MacBook Air? It installs correctly and USB mouse works but not all the hardware.https://europeschool.com.ua/profiles/ticoticas/xocyh-no-cobro-ni.php
4 Ways To Get Windows On Your Mac
Installation succes but after i shutdown and on the macbook and hold the option button theres no other drive. Only macintosh hd. Please help me to fix. Thank you. Mac log will show and and box telling me that i need to reinstall the mac OS. I wonder if this would work with a partition in the internal drive. I have a SSD drive which is not the original Apple one it was too small but the new one does not support Bootcamp.
I wonder if this procedure may help me install Windows 10 in a different partition of internal disk without using bootcamp. Can someone tell me the purpose of installing and running Windows from an external drive instead of internal drive?
How to install Windows 10 to portable USB drive to use on a Mac
If I use an external drive for Windows instead, will Windows run quicker when connected to the Macbook? You might not have a ton of space on your internal drive, or for me I have 2 computers and I only use Windows for specific software, so it makes sense to be able to carry it with me. If you have an external SSD, and your internal drive is a hard disk, I think it should be faster.
I tried with the thumb drive still connected, and got a busy error. Solution was to use disk utility and eject just the partition disk2s1 , leaving the drive disk2 alone. Even after reconnecting to my network it just boots into OS X. This worked finally. I have to try multiple times with different hits and tries.
