Error creating bootcamp USB installation.

I'm trying to create a bootcamp installation of Win7x64on my 2011 MBA 13.

Using an ISO file and BootCamp assistant when it says copying windows files it suddenly stops at about 40% and nothing more seems to happen, I do spot some harddrive activity using activity controll put it seem painfully slow, any ideas?

I don't recall exactly how long it hangs at various spots but yeah it does look a little weird at times.

If I remember correctly my total time for doing the win 7 initial install was probably around 20 minute time frame ... ( maybe a little bit more ) ... before rebooting and putting in win 7 drivers etc.

Did you remember to format the bootcamp partition as NTFS ( advanced option ) before proceeding with the install?

Did your install eventually finish or did you abort out and if so how long were you waiting before ending?

Maybe your usb drive is too small?

I am experiencing the same thing right now. Bootcamp suddenly stops while copying windows archives and it ejects the usb and says that is is not ejected properly. I have tried with different USB's and different ISO's.. but it's all the same

as for me, helped preformattind USB via DiskUtility, manually creating FAT partition named WININSTALL. after this workaround all files copied w/o any problem.
