Note: This was tested using an iMac (21.5 inch, Late 2013) with the latest firmware updates installed. There are several programs you can use, for creating a bootable USB flash drive, available for different platforms, but most of them are complex, and if not that, you will face a hard time dealing with. Creating a bootable USB flash drive, CD or DVD is the maiden step to give new life to your existing or brand new PC with a new operating system.

You could argue also, that creating a blog with the sole purpose of explaining how to create a bootable usb flash drive under mac os x is rather silly, too. When the Startup Manager icons appears, choose the external drive icon labeled EFI Boot.You probably noticed that this is a rather silly title for a posting. Restart the Mac and immediately hold down the option key.With the following command the data on the disk (your USB stick) will be deleted With this command the USB stick was re-partitioned to have 1 partition without formatting and 100 of the size of the stick.Use the steps given below to create a Windows 10 bootable USB on Mac using Terminal. But first someCreate Bootable Usb Drive Mac Os High Sierra. First partition is FAT and has syslinux in it 2.Anyway, so really how to create a bootable USB stick now, under Mac OS X ? I shall describe one way to do this, for the example of a NetBSD installation. What I have understood so far: MP1,1 can boot from MBR stick if: 1.Once you insert the flash drive for the first time, your Mac should automatically install the necessary driver software and a USB flash drive icon should pop up.What happens when you start a typical PC, is that the BIOS will â after having gone through some testing/self-check stuff we donât care about â try to start the OS. Run the command diskutil eraseDisk MS-DOS WINDOWS10 GPT ![]() For CDs the situation is different, but basically the same. Hence there is no MBR, and the BIOS will directly try to execute the VBR boot loader. The MBR boot code will then give control to the executable code in the VBR, which will then start the OS.If you are booting from a floppy, there are no partitions, just one volume. The bootable partitionâs analog of the MBR is the VBR = Volume Boot Record, whose format will depend on the filesystem type of that partition. This boot manager will usually try to boot from the partition, which is flagged as bootable. For sake of concreteness letâs assume it is bound to /dev/disk2. The easiest way to find out which device file it assigns to, is to typeIn command line, while the stick is mounted (i.e. Creating a NetBSD installation disc on a USB flash driveIf you insert a USB flash drive into your Mac, the OS will associate to it a device file /dev/disk, where n is some natural number. Before you start, make sure that you donât have any volumes of your stick mounted usingThis should unmount all the volumes on your flash drive. Instead I will to describe setting up your stick with âfdiskâ. Since this tool is rather user-friendly and self-explaining, I wonât describe it here. The first way is to use the Mac OS X Disk Utility. There are at least two ways to do this under Mac OS X. List of excel shortcuts for macNote that the numbers given in the above example donât matter actually. The option â-c 1024 -h 255 -s 63â specifies the âBIOS geometryâ fdisk should use. If you choose to do so, you will have to append the â-f /path-toâ¦.â to every fdisk command below. If you want to use your own MBR boot loader, you have to specify an MBR template for fdisk to use via â-f /path-to-a-mbr-template-fileâ). It will use some default boot strapping. ![]() You donât want to overwrite your MBR, but rather your boot volume and your VBR. Now doDd if=/whereever-you-have-download-it-to/boot-big.fs of=/dev/disk2s1Note that itâs really âdisk2s1â and not âdisk2â. If youâre planning to install NetBSD on a x86 machine for instance, this would be â/NetBSD-/i386/installation/floppy/boot-big.fsâ, on your favourite ftp-server. Download a suitable boot image. There doThe MBR part of the USB stick is now correctly set up, and we can copy the boot image onto partition 1. To install the NetBSD boot image, we need to have a partition of type âNetBSDâ = 0xa9 = 169. Otherwise, itâs pretty straight forward. Really the important thing to note here is the â-b 512â option.
