Your Bootable Usb Could Not Be Created Bootcamp

[Onfroi Baird]

Ihave a Mac Mini with OS X version 10.8 and Boot Camp version 5. I am trying to create a bootable USB drive using Boot Camp. I am using a Windows 7 Pro iso file and a 4 GB flash drive to create it. I select 'Create a Windows 7 install disk' along with the other two selections. Everytime I try it, I get the same error message of: Your bootable USB drive could not be created. An error occurred while formatting the disk.

If the install.wim or boot.wim file on the ISO is larger than 4GB, then BCA does not copy the file to the USB since FAT32 file size limit is 4GB. This is usually the case when you have mixed 32-bit/64-bit ISO or multiple Windows variants in a single WIM file.

Thanks. I was putting the fact that I couldn't get Boot Camp Assistant to put Windows 7 onto an 8Gb flash drive down to Disk Utility on Sierra. After numerous failed attempts, I tried your solution. Things seem to be chugging along just fine now.

I have the ISO stored on a hard drive, when I used the ISO (Windows 7 x64) I get the same error as above but my disks in disk utility are unmounted, would it be the hard drive which is messing up? Any help would be greatly appreciated.

I'm running into a frustrating issue where I need to create a Windows 10 bootable USB for my Macbook Pro 2023, but every attempt to use Boot Camp Assistant has ended in errors. This has left me in a bit of a bind, as I'm keen to find an alternative method that bypasses Boot Camp altogether. The goal is to successfully prepare a USB drive with Windows 10 installation files, which I plan to use on a PC. If anyone knows how to do this directly on macOS, avoiding Boot Camp issues, I'd really appreciate a simplified guide or tool suggestions to get this done.

There are many ways and tools can be used to make Windows 10 bootable USB installer on Mac, like rufus, WonderISO or Unetbootin. But for me, I used to installed windows 10 in a VM (vmware i think is what I used) on Mac and then created the USB drive from there. I wish that you had known about this method.

Bootcamp assistant app is removed from Apple Silicon on Mac so you can't create Windows 10 bootable USB on Mac with Bootcamp app. I am using WonderISO on my Apple Silicon Mac running the latest macOS Sonoma and it only takes 3 clicks to create a Windows 10 bootable USB on my Mac.

Parallels Desktop, a popular virtualization software for Mac, allows you to run Windows and other operating systems within macOS without needing to reboot. So you can create Windows 10 bootable USB on Mac in a Windows virtual machine.

Firstly, you need to have a copy of the Windows 10 ISO file. Microsoft provides this file for free on their website, intended for users who need to install or reinstall Windows. Download this file to your Mac before proceeding to the next steps.

With the Windows 10 ISO file downloaded, the next crucial step is to obtain a USB drive with sufficient storage space. Typically, a drive with at least 8GB of space is recommended. This ensures that there is enough room for the Windows installation files and any additional updates or drivers you might need to include in the bootable media.

Once Parallels Desktop is installed, you can use it to create a new virtual machine using the Windows 10 ISO file. During the setup process, Parallels will ask where you want to install Windows. At this stage, instead of installing it on a virtual disk, you'll choose your USB drive as the installation destination. This process effectively turns your USB drive into bootable Windows 10 installation media.

However, it's important to note that directly creating Windows 10 bootable USB on Mac through Parallels Desktop might not be as straightforward as using dedicated software for making bootable drives. It takes more time and storage space on your Mac.

If you want to create windows 10 bootable USB on Mac without bootcamp, you can try using a different tool called Etcher. Etcher is a free and open-source tool that allows you to create bootable USB drives from ISO files. Here are the steps to create a Windows 10 bootable USB on Mac using Etcher:

It becomes much challenging to create Windows 10 bootable USB on Mac as Bootcamp is not available on Apple Silicon Mac. Instead, you can borrow another Intel Mac and use Bootcamp to make a bootable Windows 10 USB on Mac.

Step 1: Open the Boot Camp Assistant in the Utilities folder within your Applications folder. Alternatively, use Spotlight search (Cmd + Space) and type "Boot Camp Assistant" to find and open it.

I found a way to install Windows on system without Mac OS system. You will need a USB with a Mac OS system on it. Reason why you will need to format the HD of the mac. With the system off. Turn on the mac. Access the boot up Options menu. Select the USB with the mac os. You will not be loading the Mac Os system. Don't worry. It will load to install the Mac OS system. You click the desktop and select Disk Utility. Choose the hard drive. Select Partition. Select one Partition. Under the Partition window Select Master Boot Record. This will allow you to format the hard drive that is not GUID partition that is for Mac. Once that is done. You are golden. Make sure you have a bootable USB with Windows on it. I used a bootable CD with Windows 7. When selecting the bootable media, it will load windows. You may receive error that unable to use the hard drive. No worries. Select the hard drive, delete and format. and Try again. This should allow you use the hard drive and install windows. No boot camp and no Mac OS on the system. If you need to get drivers. Try using IOBIT Driver Booster. It is free. Or you can view the devices in Device manager to locate the kind of devices that maybe needed to be updated.

@Delaney_Justin Tried this today. My commands seemed to have worked. Files were created on my USB Flash Drive, but still doesn't seem to be recognized by my new PC. Do you have ideas on how to verify that the correct files were created? Maybe I messed up the path part?

I got me a hand me down iMac 27" late 2015 from work and just used Ventoy to boot into HirenBootcd. From this Windows recovery environment I started an installation for W11 with the bypass method for the requirement check. I had to manually look up all the drivers and the only one that gave me trouble was the audio which I managed to fix after tons of possible options on the sound driver end.

So now I don't use bootcamp and can install all the regular Windows drivers for the hardware. It runs like a charm and I'm surprised as to how capable of a machine it is this way. It runs some emulators and games pretty good as well.

o, for the M1 chip, Boot Camp should work just fine without any additional software like Parallels. However, if you have an older model with an Intel processor (M2/M3), then using Parallels is necessary in order to run Windows alongside macOS seamlessly on your machine.

I started my work on Bootcamp handling by creating a bootcamp WIN 10 Partition with the Mac Bootcamp assistant in Mojave. Then I created an image from that with Winclone 8, I removed the Bootcamp partition with disk utility, created a new exfat partition and restored the image on that. Quite easy like in these videos. But then, when I tried to boot, I got only an error message:

Thank you for your prompt answer. For me it was a test how reliable a backup with winclone is and so I took the easyest case. It was my Macbook 2017 on which I created the bootcamp partition and where I made the restoring of the winclone backup. And this failed, not a good sign for the software when even the easyest case does not work.

Thank you for your help with this link, but in the meantime I found a workaround to be successful with my test. I made the restoring without update of the BCD. That let Winclone freeze short before completion so that I have to kill the program, but the restored Bootcamp partition could be booted. Again not a good sign for this software.

I use command line version to install Windows a lot of times

sudo /Applications/Winclone.app/Contents/Resources/winclone

and it works perfectly from Windows 7 x64 to Windows 11

I never had any problems

I have a new iMac running El Capitan, and I used Boot Camp Assistant to create a partition and install Windows 10. I booted to it, installed the boot camp drivers, installed one piece of software, uninstalled a bunch of the stupid crap that Windows 10 insists on installing, ran sysprep, then rebooted into the Mac side. I ran Winclone 5.5 Pro, selected the Boot Camp partition, saved an image, made it self-extracting, and copied it into Casper. During the imaging process, it looks like it's doing something, but the boot camp partition formats as FAT instead of NTFS (despite NTFS being selected in the configuration), and no data exists on it. I'm testing this process on an older iMac, from late-2013 (I think). It did not have El Capitan on it, but it does now, and I disabled SIP just to be sure.

Have you tried disabling SIP? We tried to install from a Winclone PKG and if the OS was 10.11 it wouldn't ever install properly until SIP was disabled. This is also an interesting read about SIP from TwoCanoes -capitan that shows how Apple does the Boot Camp Assistant by creating a temporary partition.

A couple of things.

As already mentioned you need SIP disabled.

You can make the WinClone into a completely self configuring package (I think) so it will even cut of a piece of the partition.

if you do successfully get it down, you may still need to run Winclone under OS X and use the "Make EFI bootable" option.

We have disabled SIP on the "target" machines. We found that uploading the Winclone package through Casper Admin was zipping the file. We had to unzip it, then re-open Casper Admin and create new BOMs. Once that was done, we could add it to the configuration, and it would partition correctly and copy the files. However, even then, it wouldn't boot.
