"Your bootable usb drive could not be created" - Boot Camp Error

Got the same problem.

I have the one iso on a USB stick and I just get the error.

Apple is just as frustrating as Windows can be - at least for Windows there are more solutions online than for the relative small OS market.

I was having this same issue, but my ISO was definitely not mounted. It turned out to be an issue with the ISO file, even though it was ripped straight from the DVD. I just downloaded a new file (google "windows 7 iso") and it worked straight away.

w7forums has the iso I used. It seemed like a more legit way than downloading from a torrent, as they are trial ISOs that you just need to register with your valid key upon installation.

I was having the same issue: Error message when trying to use an .iso i knew was perfectly fine.

Unmounted as previously mentioned and still had the error.

Logged out and back in after unmounting. Restarted bootcamp assistant and it worked this time. Just an FYI for the folks out there still struggling. 🙂

in little bits in different ways apple is becoming no longer the comany I once believed in so much.

For it to be SO hard to firstly get bootcamp to work as it should when you dont have an internal optical drive is ridiculous seeing half the computers they sell dont have them anymore.-------------------------

But not being able to create a bootable image because the one your using as the source is mounted AND no suitable error to give you a clue is simply missing the point of why people are mac users.

lucky for them there still isnt a better alternative

This is a long standing thread but because there was a post as recently as one month ago I will post my results. I had this same issue, I resolved my problem by formatting the drive myself first. Not sure why it would have failed but it ran fine after manually formatting. Hope this helps someone.

The unmounting works for me!

I had the same problem, all i did was plugged it into a Windows PC and i recieved the Scanfix message, it fixed my flash and i formatted it, it worked very well...maybe apple does need to work on its error messages after all! I hope you guys find this helpful

Thank you so much! Much appreciated.

I know it's three years later but Stephen I love you
