Boot Camp 'Your bootable USB drive could not be created' error

The 8G USB drive has a model number SDCZ60-008G-A46. It says on the front of the package that it is USB 3.0 compatible but the back of the package and the manufacturer website identify it as a 2.0 drive.

The USB ports on the Mac Mini I'm not quite clear about. The user manual says it has four 3.0 ports. Under system report it lists three USB Hi-Speed busses (one of these is related to the Thunderbolt port), one USB 3.0 Hi-Speed Bus and one USB 3.0 SuperSpeed Bus.

I reset the SMC and NVRAM. It is booting up to OSX now.

The 100G BootCamp partition shows up under the Finder

I was able to use that USB installation drive you helped me to create to get it to install as a virtual machine under Parallels 10. I think that will be good enough for my purpose. I'm just going to remerge the Windows partition into the Mac partition using Disk Utility.

I greatly appreciate all the help you gave me.

I had this problem and looked through all the suggestions in this post.

The issue I had was that I had downloaded the Windows 10 Single Language edition (which then threw the error in Bootcamp). However, once I had chosen the standard Windows 10 (and then chosen the English language product language) I had an ISO named Win10_1511_English_x64.iso which is now copying files onto a flash drive via Bootcamp.

This is where I downloaded the ISO.

Hope this helps some people. 🙂

If this post is read by anyone I hope it saves you time. If you get this error. Uncheck the the top option in bootcamp. You will then get the meaningful error message is that you need to reformat your usb/drive. Do that, re-check the first option in bootcamp and then continue. This removed the problem for me. THE USB DRIVE needs to be a FAT file! Got it? I wish this could have been displayed by Apple and saved me a few faff hours.

I've tried unmounting the ISO in disk utility but every time i try to re-create the the bootable usb it gives me the same error. "Bootable usb could not be created".

I've made sure the ISO file isn't already on the USB so its currently in my documents folder. Not sure where to go from here, most of the simple troubleshoot problems said before haven't removed this error.

The USB you have purchased contains mixed 32-bit/64-bit Windows installers. A single 'bit-ness' installer is about 4GB. Please download the correct single ISO image from https://www.microsoft.com/en-us/software-download/home and try again.

I formatted my 128 gig USB and made it FAT32 and cleared everything off of it. I followed all of the instructions ITT and still have problems. I made a video detailing the trouble:

please help!!

Eh, this is indeed very frustrating. ^_^

I have the same problem. I have a iMac Retina 5K 27 -inch Late 2015 with OS X El Captain 10.11.4

I have bought a Windows 10 x64 home edition

Tried pretty much all of the above:

1) Formatted Usb drivers in MS-DOS FAT

2) tried 4 different USB drivers

3) Unmounted the iso. It keeps mounting himself back any time I try to use bootcamp. I tried to unmount it on the flight... still does not work

4) Obviously my iso file is on my computer ( I cannot understand how anyone can even think to leave it on Usb, while trying to install it 😀)

5) My file is Win10_1511_1_English_x64.iso cosistent with other users

I am at a loss. Obviously, this is not a cheap computer that I bought it under the impression that I could install Windows. No Windows=no work which pretty much means I have a useless machine ^_^.

Any help would be appreciated.

Thanks

Hi Loner T,

thanks for the reply:

1. MD5 (Win10_1511_1_English_x64.iso) = a4fde74732557d75ffc5354d0271832e

Hope this is what you need

2. IMac 27 inches does need a usb. I installed Windows on my Macbook pro 2015 without a Usb driver. The iMac bootcamp is different. If you read the post you can see that iMac is not supported.

Still seems like I cannot find a solution 😟

put the file on ur USB drive. than put a duplicate of the windows file on your desktop.

when it comes to choosing the disk in bootcamp. go and choose the file on your desktop DO NOT CHOOSE THE FILE ON YOUR USB DRIVE. YOU SHOULD BE GOOD. GOOD LUCK

how do I unmount a file?

Just don't put iso in your flash drive. When open bootcamp, choose the directory of iso which is on the hard drive of your Mac. Hope things will work for you.

Solution:

1. Open "Disk Utility"
2. On the left side of programm, choose file with file extension ".iso"
3. Pull out all files with extension ".iso" (remove)
4. Close utility

That's it 🙂

we very often oversee the little obvious things, glad it solved it for you.🙂
