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.

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.
According to the first answer here, -a-bootable-usb-drive-from-a-dmg-file-on-windows, there's a tool with a free trial called TransMac that can do it. Just make sure the USB drive is formatted with GPT and not MBR.
I know this question is old but it is still valid. I was never able to write a Mac installer image to my Flash Drive and have it bootable, unless I did it on a Mac. Using Michael D. M. Dryden's Link, I was able to use the Diskpart command to clean and prep a GPT partition on a flash drive for an OSX Mavericks install image.
I used TransMac on Windows 7 to restore the image file I had to the Flash Drive, it created a bootable Mac image on my flash drive. Someone had reported that the method for using DISKPART did not work, but I have done this twice and it works remarkably well, and it's the only method I could find to create a Mac-Bootable Flash. I've been trying to post this to confirm that it works for some time, I just hope it helps someone else, because it is a very easy solution.
In fact, there are very few ways that can be used to write DMG image file to a USB drive and have it to be bootable on a Windows computer. As far as i konw, some third party tools like Transmac, poweriso, etcher or sysgeeker's WonderISO.but none of them are free, I suggest you download the trail version and use it for 3 times without paying.
I had this problem with a friend computer, it was an old iMac and I'll tell you it is not going to be easy.The first thing you have to do is make sure what model you have (the year when your computer has been released) then check on the official apple website to see what is the latest macOS or Mac OS X version available for you computer.In most of the new mac computer, you can just press cmd+r while booting and the mac will automatically download everything you need to install the system, but the oldest does not have this tool.In this case, you have to download the dmg file, that can be found on the web, for example, one websites that provides some macOS and Mac OS X is this (for El Capitan, if you need another version, I'm sorry but you have to search for it).Here things start to get a little tricky.First of all you have to flash the image on a USB drive, I recommend etcher, that works on everything (Mac, Linux and Windows too) it's extremely easy to use and you just need to select the drive and the image and etcher will do everything by itself, plus it's free here.When the USB drive is ready you can plug it in you mac and press alt (option) while booting, you have inserted a firmware password, it will ask you to unlock the firmware by inserting that password, else it will take you to all the bootable drives, including your USB device.If you see the mac logo with a stop icon over it, it means that you downloaded a too new version that is not supported from your mac, else it will start.When it start, it won't install, saying that the system can't verify the downloaded image, that's why you have to navigate on the "utilities" menu on the top bar and open the terminal.Now you have to choices, change the date & time, which can work, but may not.That's basically because every image of mac has a certificate that can expire, so, if the certificate is expired you won't be able to make it work, unless you change the date (the date is different from mac version to mac version, so based on that you have to change it, usually just search for when was that version released and se the current date to that date or even one or two days later to make it work). Then try to install the system, if this does not work again, you can start the installation without verifying the image, but you should really trust the image you're using from being corrupted or modified (just to make sure the download went right, use the SHA-1 code to make the file has been downloaded right).So, to proceed without verifying the image, from terminal, type in this command: sudo defaults write com.apple.frameworks.diskimages skip-verify truethen, start the installation. (Is possible that you won't need the sudo at the begin, in that case just remove it from the command and start from "defaults")Now you should be able to install macOS from a USB drive...Just a little thing, make sure to have formatted the disk before proceeding, I would recommend to make a partition that takes the whole disk in mac Journaled format, then if you want you will be able to encrypt the disk (the installer will ask you to do that later), instead, if the disk was encrypted before, you will have to insert the encryption key of the disk to continue the installation process.Really hope this help, I spent a lot of hours to do this on a really old iMac from 2008... and now it works!Good luck!
I've tried many tutorials on how to create a mac bootable USB drive from Windows but none of them worked. So, I've come up with my own solution that worked fine with any DMG I've tested. Please find the details on my github page.
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.
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.
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.
