Prerequisites
Before you start creating a bootable USB flash drive to install Windows (XP, Vista, 7, 8, 8.1, 10), you need to make sure that:
- The USB drive is empty and properly formatted
- The USB drive is bootable
- Your BIOS/UEFI is properly configured to boot from the USB flash drive first
- You have the ISO image of Windows XP, Vista, 7, 8 or 8.1. If you have the original Windows installation disc, you can use that instead of the ISO image.
- Software needed to write the ISO image to the USB drive or alternatives, such as Easy USB Creator 2.0 by NeoSmart or the Windows 7 USB/DVD Download Tool by Microsoft.
USB Drive
The USB drive you want to make bootable should have at least 4 GB in available size.
BIOS/UEFI configuration
To make sure that your BIOS/UEFI is configured to boot from a USB drive, follow our Boot from USB drive guide. You need to make sure that:
If a Boot Device menu doesn’t appear on your screen where the USB drive is plugged-in, check the BIOS/UEFI settings. A Boot Device menu can look like this, depending on your computer model and Windows version:
If you are using a new computer with UEFI/EFI, make sure that the Boot Legacy option is enabled:
If you’re using a computer with Fast Boot option, make sure that Fast Boot is disabled.
If your BIOS menu doesn’t list a USB item in the BIOS settings, it may mean that it can’t boot from a USB drive. You can try with the USB drive plugged-in and then boot into BIOS directly.
If the item doesn’t appear, you need to use the original Windows installation CD or DVD to install Windows or access the repair tools.
If you need to use the repair tools of an original Windows installation CD/DVD, you can also use Easy Recovery Essentials and run Automated Repair to automatically find and fix boot errors.
ISO image
If you don’t have the ISO image to create the bootable USB drive, you can download an official image from Microsoft’s website.
You need to have the product (or license) key.

Part 3 : Create A Windows 10 Bootable USB on Mac without Bootcamp
As we mentioned above, creating a bootable USB Windows 7/8/10 on mac OS isn’t as simple as you might think. You will need Terminal tool on Mac to perform some command. Before we start make sure you have an effective ISO file and have USB flash drive with not less than 4GB capacity. Here are the steps to be performed on a Mac to create a Windows 10 USB Bootable Installation Drive on mac.
Step 1. Connect your USB drive to your Mac.
Step 2. Open a Terminal (under Utilities)
Step 3. Now you need to Run diskutil list and confirm the device node assigned to your USB flash media disk2.
Step 4. Type the following command.
hdiutil convert -format UDRW -o ~/path/to/windows-10-iso.img ~/path/to/windows-10-iso.iso
Step 5. Replace /path/to/downloaded.iso with the path to where the image file is located; for example, ./windows10.iso). This command will convert the ISO file to IMG format.
Step 6. Type the following command to check the location of your USB drive:
diskutil list
Step 7. Next, you need to type the command to Unmount the USB drive, then replace /dev/diskX with the location of your USB drive.
diskutil unmountDisk /dev/diskX
Step 8. Finally, run the following command to create Windows 10/8/7 bootable USB on Mac.
sudo dd if=/path/to/windows-10-iso.img of=/dev/rdiskX bs=1m
Step 9 . Then try to replace /path/to/windows-10-iso with the real filepath of the ISO file and /dev/diskX with the location of the USB drive. This command will take some time, and once it’s complete, you can eject the USB drive by this command: diskutil eject /dev/diskX
Once the process is complete, you can see the data will be copied and your USB will be bootable.
