Fix Error Your bootable USB drive could not be created

This video and article will show you how to Fix Error Your bootable USB drive could not be created.

Hi All
When installing Windows on a Mac I came across this error when I was trying to create a USB drive. The problem is the DVD is already mounted in Disk utility and when this is the case the Boot Camp Assistant cannot mount the DVD at the same time so you get this Error Your bootable USB drive could not be created.

Your bootable USB drive could not be created

The fix for this is pretty straight forward. You need to unmount the USB drive in order to get this to work. But also you will need to make a copy of that DVD so that you will be able to continue along with the setup.
If you want to know how to create a ISO or DMG file from a DVD then you can follow the 123myIT.com video here.
How to create an ISO file on a Mac

Once you have created your DMG or ISO file, you can then start the process again with the Boot Camp Assistant. However this time instead of selecting the DVD drive, go into your Documents folder and select the newly created DMG or ISO file. This should then allow you to continue on with the installation as normal and Fix Error Your bootable USB drive could not be created one and for all.

Users that have upgraded to Yosemite may also get this same error. If this is the case just follow the steps outlined above and you should hopefully resolve the same error.

If you have a Mac and have set a password when you leave your Mac alone for a short time it will go into sleep mode or start the screen saver. Sleep mode is designed to save battery life and will start after a very short time. When you wake your Mac you will be prompted for your password.
Well you can tell your Mac how long you want this time out to be before you get prompted for your password. Some people might find it annoying to have to type their password in every few mins of non activity or they just might not need this security feature at all.

Fix GPT Error: Windows cannot be installed to this disk

This video & article will show you how to Fix Error: Windows cannot be installed to this disk. The selected disk is of the GPT partition style.

The old GPT partition style error! Must be close to the most frustrating and annoying errors I have encountered in my time working with Mac.
In this video on how to Fix GPT Error: Windows cannot be installed to this disk error message, I explain a few different ways to try and fix this error. However lets talk about the possible root cause of the error.

Most people myself included get this error when trying to install Windows on a Mac and seems to be caused by the hard drive not being configured for UEFI mode. If your Mac or PC is UEFI-based then to install Windows your hard drive must be set up as UEFI mode or legacy BIOS-compatibility mode.

GPT Error Message

If you want to know more information on this issue then you can the Microsoft reference on this link.
Windows Setup: Installing using the MBR or GPT partition style

For example, if you receive the error message: “Windows cannot be installed to this disk. The selected disk is not of the GPT partition style”, it’s because your PC is booted in UEFI mode, but your hard drive is not configured for UEFI mode. You’ve got a few options:

1. Reboot the PC in legacy BIOS-compatibility mode. This option lets you keep the existing partition style. For more info, see Boot to UEFI Mode or Legacy BIOS mode.

2. Reformat the drive for UEFI by using the GPT partition style. This option lets you use the PC’s UEFI firmware features.

You can do this yourself by reformatting the drive using the instructions below, or if you need to preserve the data, use a third-party utility to convert the drive to GPT format.

Ok so how do you fix it? Well you can try the options mentioned in the video, however I have found the best way to fix the issue was to backup my data in OS X.

Then do a Clean install of OS X.

And then try the boot camp process again from scratch. This process should sort out your hard drive partition type and resolve the issues with Windows not installing correctly on the disk.
