booting a fresh virtual machine on a Mac host with just the needed iso attached.
writing to customer support (answer: "iso looks good, should work, please try again").
using a different iso (not matching the target device) from the vendor site (works without any issues according to instructions, but can't update my device…).
gparted and fdisk mkfs.vfat on a Linux machine.
Windows on-board tools on a PC for re-formatting the sticks.
different versions of DiskUtility (Sierra and Mojave).
writing the iso file with dd directly to the stick (and in another round using Balena etcher and universal usb installer).
partitioning the sticks to either MBR or GPT.
erasing the sticks a few times with DiskUtility.
The external USB-drive never shows up in the boot menu. What then doesn't work is booting a MacBook Pro 2015 from that stick. The instructions ( PDF) for a firmware update utility say to use Unetbootin on MacOS to write an iso-file to a FAT32 formatted (erased) USB stick. ConclusionĪll in all, Universal USB Installer is one of the easiest ways to make your first steps into the world of Linux and it comes with an impressive list of supported Linux distributions.Goal is updating a NVMe SSD firmware on a Mac without optical drive via USB stick that should contain a minimal Linux, flasher and payload. It doesn't take more than five minutes and Universal USB Installer does an amazing job, proving to be very effective for most of the supported Linux distributions. Select the USB driveĪnd the last step, choose the USB drive you wish to use, decide whether a format is necessary and set a persistent file size for storing changes. Secondly, you need to provide the location to the ISO and it doesn't matter whether you downloaded it through Universal USB Installer or the file was already there on the hard disk. Grab Linux distributions from the Internet or specify the ISO fileĪnd not only that the application comes with support for both older and newer versions of the most popular Linux distributions, but it also provides direct download links to lend you a hand in case you don't have the ISO file on your local hard disk. It doesn't really matter whether you want Ubuntu, Kubuntu, Xubuntu or Linux Mint, Universal USB Installer supports them all. Pick the desired Linux distributionįirst of all, choose the Linux distribution you wish to use. The whole process of copying a Linux distribution on a removable USB device has been designed as a wizard, so you just need to follow a total of three steps to get the job done. Universal USB Installer is a very easy-to-use application that allows you to run a live Linux distribution from a portable USB flash drive.Īlthough Linux isn't quite addressed to beginners but you still want to try this version of operating system, don't worry because Universal USB Installer relies on a fairly user-friendly approach.
