You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful if you want to install macOS on multiple computers without downloading the installer each time, or you're unable to install a compatible macOS from the Finder or macOS Recovery.
For information about the createinstallmedia command and the arguments you can use with it, make sure that the macOS installer is in your Applications folder, then enter the appropriate path in Terminal:
I'm a computer novice and i wanna reinstall my windows 10 for my HP laptop since it was crashed, but i have a macbook pro, so I was wonder if it's possible to create a windows 10 bootable installer USB on macOS without terminal?
****EDIT**** The ExFAT formatted drive with Windows ISO did not work as a bootable drive. I had to create a Windows partition on my hard drive and boot into that to make a functioning boot drive.
This trick does not work at all! Only a small portion of computers recognize exFAT USB as bootable device. It failed on my Dell desktop. FAT32 is more recommended. In addition, a single copy-and-paste of Windows 10 ISO file is not going to make the drive bootable.
Otherwise, try UUByte ISO Editor app instead, it is more suitable for beginners. It only took me 7 minutes to make a bootable Windows 10 USB on my MacBook Air (Big Sur with M1 chip) . No commands and hassle free. You can refer to this step-by-step guide (Method 2):
If you are using a newer Windows 10 ISO (after version 201809), then UUByte ISO Editor is the best app for creating a bootable USB on Mac. It automatically splits the large ISO file into small parts so the Windows installation files can be sit on a FAT32 partition, which is the only working file system supported by Mac for Windows install. Also, this app works on latest Big Sur and M1 Mac as just tested it on a M1 MacBook Air with macOS Big Sur 11.5.
If you are using an old version of Windows 10 ISO, then Boot Camp Assistant can help you get this done easily. It is a built-in free app shipped with macOS by default. However, this feature is removed from Boot Camp app on macOS Big Sur. You can still use this app for creating bootable Windows USB on Catalina and Mojave as far as I know.
The problem is that on MacOS that format restricts individual files from being larger than 4gb, and the install.wim file in the Windows 10 iso must be more than 4 G. Etcher doens't seem to be able to process the ISO file larger than 4 GB.
Share the tools and methods I know: How about the boot camp Assistant? Although it does not work sometimes, as a multi-boot creation utility, it can create a Windows 10 bootable USB on your Mac. If you are good at CMD, it is possible to use CMD to create Windows 10 bootable USB on a Mac in a virtual machine. But if you are a computer novice or are not know much about CMD, please find another way. If you have installed Windows iSO files on your Mac, try UNetbottin, plug in the USB on Mac, and launch the Disk Utility option. Open the Windows .iso file in UNetbottin and burn it to the USB flash drive. Generally speaking, the task is OK completed in 15 minutes. Suppose you are not interested in the above software. I think UUbyte iSO Editor is enough. Just download and install this software on your Mac and run it. Next, you can burn iSO files to USB. The whole process won't take a long time. UUbyte iSO Editor is a good choice for computer novices. And can quickly complete tasks without any technical requirements.
It does the job well though it is not free. You could spend hours by trying the other alternatives. I learnt from my lesson. Wasted three hours with Terminal app and only 7 minutes with UUByte ISO Editor.
For the fewest issues or problems with a bootable windows 10 iso the best option is to find a windows computer or ask a friend, neighbor, relative, or local computer store to make the iso on a computer with Windows.
You can create a disk image that includes the data and free space on a physical disk or connected device, such as a USB device. For example, if a USB device or volume is 80 GB with 10 GB of data, the disk image will be 80 GB in size and include data and free space. You can then restore that disk image to another volume.
Copying ISO to USB on macOS is is not a simple matter because you may encounter a variety of strange issues in the production process, whichever way you do it, such as "couldn't validate source" when burning ISO with Disk Utility, Bootcamp doesn't work or USB won't boot. Many of the problems you face is because macOS X doesn't natively read the particular ISO image file, which is likely NTFS file. So, if you intend to burn a Windows 10 ISO image file into a bootable USB installer on a macOS without Bootcamp and less error-prone. you will need to find the most reliable and simplest way to burn ISO image to USB drive.
Now, If nothing else, you should get a bootable USB installer. You can re-insert your USB drive to computer and check if there are some files and folders contained in it, especially a setup.exe and an autorun.inf file. Be careful with dd comamnd, as if you get the device wrong or execute the wrong command, you could overwrite your OSX drive.
The second I highly recommend is WonderISO tool, which is a top alternative solution for having your ISO bootable without involving complex command line. It should be used by either invoices or experts since it comes with a intuitive interface, there are 5 functions especially designed to handle ISO image file that can meet different customer needs. They are "Burn ISO", "Extract ISO", "Create ISO", "Edit ISO", "Copy ISO from Disc". To burn ISO to USB on macOS with bootable info (UEFI or MBR), just click "Burn ISO" option, import your Windows ISO and select boot type, that's all! I've tested it twice and it was be able to boot up my Win 10 ISO on another computer and there is no shortage of necessary drivers.
Step 3. Make sure all settings are complete correctly, just click BURN button to start copying ISO file to USB on maOS byte-by-byte. This may take you anything from 5 minutes to 20 minutes, depending on the writing speed of your USB drive.
Once it's completed you can exit WodnerISO tool and remove the USB key from your OS X machine,now, your USB drive should be bootable with Windows ISO. You can boot up your ISO on on another Windows computer.
As you see, copying ISO to USB on mac can be done within 3 steps without using complex settings or command. After test, I was obliged to admit the fact that WonderISO is consistently reliable in creating bootable USB drive. I suggest you to give it a try.
Step 3. Please note that the Mac with USB 3.0 ports are not currently supported under VirtualBox , so you may find your Windows won't read the USB 2.0 port, that's because your system lacks of VirtualBox Extension Pack, download and install it on your Windows (VirtualBox ) , then click Ports from the settings in the virtual machine, just enable the USB 2.0 EHCI.
Step 4. When you attach your USB drive to you mac, it will be identified by mac OS X but VirtualBox, that's because only one OS can be able to control a USB port at a time. To fix this, what you need to do is just eject it from your mac OS, then VirtualBox will automatically recognize your USB drive, namely you can see your USB in the Windows OS.
This is one of the main reasons you should consider making a macOS bootable USB when your device works properly. However, if none of your devices (MacBook, MacBook Air, MacBook Pro, iMac, Mac Pro, or Mac Mini) are not working when you need them the most, you can use a Windows computer to rescue your Apple device. You can use a Windows 11, 10, 8.1, or 7 computer to quickly create a USB bootable installation media to reinstall macOS Ventura, Monterey, Big Sur, or Catalina on your Mac.
If the USB flash drive is not working with TransMac, it could still be a partition problem. In this case, you may need to redo the entire process again. However, this time, you should use the following steps to use the Diskpart command-line utility on Windows 10 to create the appropriate GPT partition, and then follow the above instructions.
Once you have formatted the USB flash drive with a GPT partition, you can use the instructions mentioned above to use TransMac to create a bootable media, but this time skip steps 5 through 10 and continue on step 11.
Windows 10 is a very specific bootable media, so the process is a bit involved. For generic Linux installation ISOs this procedure would be simpler. So the first two steps are the same, then Windows and Linux have separate procedure.
Use this option and download Media Creation Tool if you want to create bootable USB media to perform a clean install on new or existing hardware. To get started you first need a license to install Windows 11 or have a Windows 10 device that qualifies for an upgrade to Windows 11.
OF COURSE you need to create this script in a users directory commonly located /Users/USERNAME/bin/clone2USBwhich can be created using the following terminal commands mkdir -p /Users/USERNAME/bin vi /Users/USERNAME/bin/clone2USB or use TextEdit to create it and save it to that directory
I tried doing a bootable usb on Mac with the terminal commands and after it copied and ejected, the usb disappeared completely. It does not appear as bootable device, it does not appear in the disk utility app. Also I am beginner at working with terminal, but from what I can see, the stick as I know it (16gb) does not appear either.[IMG] [/IMG]Any clues?
There is progress with dd. You should use signal USR1 and kill the procecss with it. Then it will should you stats in terminal where dd runs. Ex: kill -USR1 1234512345 is process id from Ex: ps aux | grep dd
Yes, I found that using the disk name + partition in the dd command (eg, disk2s2) is not creating a bootable drive that will work on the intended PC-The dd does complete ok though. Tonight I am going to try just referencing the primary disk identifier (eg disk2) to see what happens. 2b1af7f3a8
