The one I struggled with in vain (4,56 Gygabites), and the other one that worked (3,95 Gygabytes).ĭon't ask me why those ISOs have a differents size for the same exploitation system, I won't be able to answer you.
Personnally, I downloaded two ISOs in my "journey" to install Windows. More precisely, it will not be created if your " install.wim" file located in " source>install.wim" (In your Window ISO file) is over 4 Gygabytes, or if any other files in your ISO is over 4 Gygabites. If you read my previous post (you should read it if you want to understand that one), I was talking about a file-size limit involved with the FAT32 format used to create your Bootable USB Drive.ĭepending on the ISO you dowloaded : the Bootable USB Drive will not be created if your ISO size is over 4 Gygabytes. So what do you think people ? Did I found something "pretty obvious when you see it" or completely useless ? Still, I have no idea why it works for some and not for others. He is copying the ISO files into your USB Drive, and as it is formated in FAT32, if you happend to have a file superior than 4Gb, you'll get an error. Your BootCamp Assistant works just fine, it's just the format he use that ruin the hole process. So I said to myself : "Hey, maybe that's why I'm getting this error message, because the format does simply not take this " install.wim" file, ( witch is the heavier file in any ISO) - (4,56 Gygabytes in my case)"."The bar gets stuck halfay because it's a long file to copy, and then my software figure that he won't be able to copy it because of this size limit, so BAM, error message "An error occurred while copying Windows files". And sadly, FAT32 is the only Bootable format for MAC. I searched, there is no way around this limit. You'll be prompted "Not enough space in the disk" or something. Even if your drive is perfectly empty and is 1TO big, you won't be able to do it. Meaning it can't copy or receive any file over this limit.Īs an example : After formating your (X) Gygabyte drive into a FAT32, try to paste any file superior than 4 gb in it.
Ok.ģ) Then, I just learned that this very format, FAT32, have a file-size limit of 4 Gigabytes. If it's not, don't bother reading the rest.Ģ) But : When creating a Bootable USB Drive with BootCamp Assistant, the software will automatically format your drive in a FAT32 format. If you're installing any version of Windows (7/8) with an ISO file :ġ) You'll note that the " install.wim" file located in " source>install.wim" (in your Window ISO file) is probably over 4 gigabytes. I din't found any solution yet, but I may have founded the real problem : Then I started to think and I made some researches. My bar stayed stucked like everybody here, and I ended up with an error messages. I had the same issue about my Bootable USB drive that couldn't be created by BootCamp. (I'm sorry if I type any mistake, English is not my native language - French is)
