This page explains how to create a bootable USB stick in a Linux System. There are dedicated articles about how to Create a Live USB stick using Windows™ and Create a Live USB stick using macOS

Version: 12.2+This applies to openSUSE 12.2 and later.

Warning: The instructions on this page will destroy all data currently on the USB stick being used. Please be certain it does not contain important information.
Warning: Do not try to apply procedures found on the internet for other distributions to convert the images into bootable sticks (unetbootin). Doing that will break the images. The openSUSE images are already prepared for being used directly on usb sticks, and can persist filesystem changes without further steps.

Download the latest openSUSE ISO file

See http://download.opensuse.org/distribution/leap/ as of Nov 2019, this repo keep all the Leap versions (since 42.2 to 15.2), following the links lead to a repo 'live' with live isos.

Official URL: http://software.opensuse.org/

Backup your USB drive

You could, if you prefer, make a backup image of the stick prior to using it for installation, with dd, and recover it after the installation. [Detailed instructions needed]

Using SUSE Studio Image Writer

These a general instructions to write an hybrid iso dvd to an usb device.

Install ImageWriter for openSUSE

Install SUSE Imagewriter with 1-Click Install

For openSUSE 15.1:

For openSUSE 15.0:

For openSUSE Leap 42.3:

For openSUSE Tumbleweed:

Or you can use this command as a root to install Imagewriter.

Write ISO to USB

  • Start SUSE Studio Imagewriter from the start menu.
  • The image writer needs root permissions. So enter the password for root when prompted.


  • Open a file manager application.
  • Navigate in the file manager to the downloaded ISO file.


  • Drag&Drop it to the Imagewriter.


  • Plug your USB memory device in your computer.
  • Select it from the dropdown menu at the bottom corner of Imagewriter.


Confirm overwriting your data on the USB device by clicking OK.


Writing the data takes a few minutes. After that your openSUSE bootable USB device is ready!

Boot Macos From Usb Drive Mac

Using live-fat-stick, live-grub-stick, live-usb-gui (Command line or GUI way)

If you'd rather not reformat the USB device and keep the ability of putting files on it and accessible by other operating systems, you have the option of using the live-fat-stick or live-fat-stick scripts from command line or live-usb-gui point and click graphical interface. You can put ISO on vfat partitioned USB stick or hard disk.

On openSUSE you can install the packages simply via yast (Leap 15.1) or via 1-click from here live-fat-stick, live-grub-stick and live-usb-gui, if you are running any other distribution, get the scripts from here and make it executable(as root, with chmod +x /usr/bin/live-fat-stick) after copying it to /usr/bin/, make sure you have syslinux and gpart installed before running it.

Run the following as root (with su -, not using sudo) in terminal to get the USB device path:

Run the following to make USB stick with vfat(fat32) partition bootable with iso copied on it:

# live-fat-stick --suse /path/to/openSUSE-filename.iso /dev/sdXY

To make USB device bootable with EFI(Secure boot capabilities) wiping all data from it, run:

# live-fat-stick --isohybrid /path/to/openSUSE-filename.iso /dev/sdX

For more help, run:

Use live-grub-stick command in place of live-fat-stick as shown in above examples if you wish to create bootable usb sticks formatted in any file systems supported by grub2, for example you can use ext3/ntfs formatted stick to create bootable USB from standard openSUSE installation iso, this allows the use of remaining space for putting other iso images or data.

Multiple iso images from multiple distributions can be added to the USB device with vfat partition when not using 'isohybrid' option, boot menu will offer a choice of distribution to boot from. Scripts does not format or remove data from the device.

Using commandline tools

Download LiveCD ISO

Download the installation image of your choice from http://software.opensuse.org/.

Verify the integrity of a downloaded image:

$ gpg --recv-keys 9C800ACA
$ wget http://download.opensuse.org/distribution/13.2/iso/openSUSE-13.2-GNOME-Live-x86_64.iso.asc
$ gpg -a openSUSE-13.2-GNOME-Live-x86_64.iso.asc

Find Block Device

After inserting your USB stick, you can find out what device it is:

# grep -Ff <(hwinfo --disk --short) <(hwinfo --usb --short)

Write ISO to USB

Finally, once you've found your block device, write the image to it. Point 'dd' to the full path such as '/home/user/Downloads/openSUSE-13.2-GNOME-Live-x86_64.iso' or change directory (example: cd ./Downloads) to where the image is contained.

If you get the message

your dd version does not support the status=progress option and therefore you have to remove it (and you will miss the writing progress indicator).

Optional steps

How to recover the USB stick for 'normal' use again

After system installation, you may want to reuse the stick as you would normally to write things on it. In that case you have to reformat it. Often people complain that Windows fails to do it.

Typically, you would simply start fdisk:

Boot Imac From Usb Flash Drive

and select:

and then:

(primary, number 1, default size to use the entire device)

Use type 6, FAT16

Finally:

This last step is necessary, particularly the -n SOME_NAME, or the USB stick will mount with the iso name.

And done. Or, you could use gparted for partitioning and formatting.

If that doesn't work try the following steps with extreme care:

If you look at the 12.3 DVD image on a USB stick with fdisk, you would see something like this (notice the GPT warning):

So, before reformatting, you have to repartition it again. And sometimes, if this fails, you may need an extra step - because software thinks the stick is a CD and thus not writable:

Boot Imac From Thumb Drive

Notice: all these instructions assume the stick device is /dev/sdX. You have to find which is yours (see “Find Block Device” section above). An error here will destroy some other disk in your system.

That destroys the boot sector, partition table, and initial structures. Any operating system should be happy to reformat it again.

If your Mac suddenly refuses to boot up properly, you might need a bootable macOS USB installer to make repairs. But how do you create such a disk if all you're left with is a Windows 10 computer? Fortunately, there's a great tool that you can use for free to create bootable macOS media on a USB drive in a Windows 10 environment. This article shows you how to download a macOS DMG file, format a USB drive using a GUID Partition Table, burn the DMG to the drive and boot your Mac from the USB. All the steps except the last one are done on a Windows 10 machine.

Part 1: Download macOS or Mac OS X DMG File

The first step is to get the DMG disk image file for the version of macOS that you want. You can get a copy of the latest macOS version from Apple download portal or App Store here. There are also several other direct download sites that offer various versions of Mac OS X in DMG format rather than the standard APP format that runs on Mac. Since you're working in a Windows environment, you need the DMG rather than the APP file.

Part 2: Easily Create a Bootable macOS USB from Windows 10/8/7 PC

You have now formatted the partition of USB drive. It's time to download UUByte DMG Editor for Windows. Although this is a premium software, you can use the initial free trial period to create a bootable macOS USB on Windows 10. After installing the application, follow the sequence of steps shown below:

Updates (Dec 8, 2020): The latest version of UUByte DMG Editor is able to format the USB automatically.

Step 1: Right-click the software icon on desktop and select 'Run as Administrator' from the contextual menu. Choose 'Run' when prompted.

Step 2: Insert your formatted USB drive, and click 'Burn' tab on the main screen.

Step 3: Click 'Browse' button to import macOS dmg file into the program. And select the USB drive name from the second row. You can also set a volume labe for that USB drive.

Step 4: Click 'Burn' button at the bottom to start the process. You will see a progress bar and wait around 10 minutes to get it done.

Step 5: Once the progress bar is at 100%, a bootable macOS USB is ready. After that, you can use that USB drive for installing macOS.

This is one of the easiest way to create a bootable macOS USB on a Windows PC. The steps are simple and instructions are pretty clear.

Part 3: Format USB Drive to GPT If Failed

If the USB drive created in above step was not seen as a bootable device on your Mac, then you need to take an addtional step before burning. That's formatting the USB to GPT.

Mostly, the USB drive was formmated to FAT32 in default when being shipped out from the factory. However, FAT32 can be only used for installing OS with legacy BISO, which doesn't work for macOS. So the next step is to format your USB drive in the GPT partition style in order to burn installation files to the desired USB drive. You can do this in Command Prompt as admin. In elevated Command Prompt (Ctrl+Shift+Enter), input the following series of commands followed by Enter after each line:
Diskpart
List disk
Select Disk X (X stands for the USB drive name that appears after the previous command)
Clean
Convert GPT
Create partition primary

Part 4: Boot Mac from macOS USB Drive for Installation

Now remove the USB drive and insert it into the Mac computer. To boot from the disk, you need to hold down the option key when you hear the boot chime. This will take you to the Startup Disk Manager, where you should be able to see the USB drive. It might have a different name, but as long as it is bootable, you'll be able to see it there. Once you select it, the computer will boot from the disk and the macOS installation will begin.

Troubleshooting

Flashing Error: You might receive a flashing error message at the end of burning process. Please don'y worry and ignore this error. The USB becomes a bootable disk and you can use it to install macOS even this error pops up.

About Official EI Capitan DMG: There has a serious bug in the official release of OS X El Capitan, which contains .pkg installer only. The burning process will fail for sure. Please use this modified EI Capitan DMG file instead, which was approved a good option.

Registration Failed: Please make sure the computer is connected to Internet and no proxy or VPB is running during registration. If the problem still exists, please send an email to support team asking for a new code.

Conclusion

The whole process might look a bit complicated if this is your first time, but just follow the instructions in this article and you should be fine. That being said, you need to be careful when downloading the DMG file and formatting your USB drive. If you don't do these two steps correctly, the output drive from the UUByte DMG Editor software won't be bootable, which means you can't install macOS from that USB drive, and you may need to do the whole thing over again.
