How to install Windows 10 on Mac
To install Windows, use Boot Camp Assistant. It's in the Utilities folder of your Applications folder.
1. Use Boot Camp Assistant to create a Windows partition
Open Boot Camp Assistant and follow the onscreen instructions:
- If you're asked to insert a USB drive, plug your USB flash drive into your Mac. Boot Camp Assistant will use it to create a bootable USB drive for Windows installation.
- When Boot Camp Assistant asks you to set the size of the Windows partition, remember the minimum storage-space requirements in the previous section. Set a partition size that meets your needs, because you can't change its size later.
2. Format the Windows (BOOTCAMP) partition
When Boot Camp Assistant finishes, your Mac restarts to the Windows installer. If the installer asks where to install Windows, select the BOOTCAMP partition and click Format. In most cases, the installer selects and formats the BOOTCAMP partition automatically.
3. Install Windows
Unplug any external devices, such as additional displays and drives, that aren't necessary during installation. Then click Next and follow the onscreen instructions to begin installing Windows.
4. Use the Boot Camp installer in Windows
After Windows installation completes, your Mac starts up in Windows and opens a ”Welcome to the Boot Camp installer” window. Follow the onscreen instructions to install Boot Camp, including Windows support software (drivers). You will be asked to restart when done.
If the Boot Camp installer doesn't open automatically, your final step should be to open the Boot Camp installer manually and use it to complete installation.

Mac Usb Format Tool For Windows 7
Recently photographers have switched from using CD/DVD’s to USB flash drives to deliver their digital pictures to their clients.
However, some photographers have run into issues where clients are not able to read the USB flash drive, prompting the photographer to switch back to using CD/DVD’s.
... but don't worry ... we've got the solution!
This article will teach you how to format the USB flash drive so both Mac’s and PC’s can read them.

If you accidentally choose the wrong disk you will not be able to recover the data without special software or even a data recovery specialist, which can be extremely expensive.
Step 6: Locate your USB flash drive. Mine displays as 2 GB SMI USB DISK Media, then underneath it you will see USB DISK. Click on USB Disk. .

Step 10: Your screen should look like the screen example below. .
.
Step 11: Now if everything looks right click on the Erase button. IMPORTANT: AGAIN, PLEASE CONFIRM YOU ARE ERASING THE CORRECT DISK. YOU WILL SEE THIS SELECTED ON THE LEFT SIDE.
A confirmation window will pop up. Click on the Erase Button. .
