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).

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. 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.

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. So basically, the USB drive cannot have any high level formatting, the Windows system should detect the drive as 'not formatted' for this to work, which it will if prepped right with Diskpart. When I tried to inject the image, Transmac told me that the drive was 'write protected'. Note: I use 'Rufus' for all other USB writing and formatting for Windows systems, it's a great app, but I had previously tried to format the drive as GPT using that, as a Fat32 partition.

DISKPART> convert gptĭiskPart successfully converted the selected disk to GPT format. DISKPART> cleanĭiskPart succeeded in cleaning the disk.

(Find the disk number) DISKPART> select disk x (from result of List Disk)ĭisk x is now the selected disk. Here are the Diskpart commands used to prep the Flash Drive, just to have them here in case my Link does not work: diskpart 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. 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 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. 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 was never able to write a Mac installer image to my Flash Drive and have it bootable, unless I did it on a Mac. First, run diskutil list and find the identifier of the USB drive (this will be something like disk2 or disk3 make sure you find the right one, since you could erase the wrong drive and lose data if you don’t use the correct identifier).I know this question is old but it is still valid.

After some research and a lot of trial and error, I found that the USB drive must be formatted with a FAT32 partition and the MBR partitioning scheme, after which you can simply mount the Windows 10 ISO in macOS and copy the files to the drive.įormatting the USB drive can be done from the command-line fairly easily. My first instinct was to use dd to copy the ISO to the USB drive (as one typically does when installing a Linux distribution, for example), but it turns out that this does not satisfy the UEFI boot process.

Microsoft provides a tool for creating a bootable Windows 10 installation drive from an existing Windows system, but not for macOS, and there is some conflicting information online about how to go about doing that. This was my first time installing Windows 10, and it turned out to be a bit of a challenge, as I opted to purchase a downloadable copy through Microsoft’s website and transfer it to a USB drive on my Mac running macOS High Sierra. I recently put together a new gaming PC for the first time in several years.
