Installing something anew, or repairing operating systems like Linux, Ubuntu or Windows can be done in various ways. The choices you’ll be familiar with are the cloud reinstallation of Windows 10, CDs with ISO files, or a USB with the corresponding system files or rescue tools. However, if you want everything on one, creating a multiboot USB is the way to go.
A multiboot USB is the universal tool for anyone who wants to reboot or repair their system or boot a live system from a USB. The advantage of a multi bootable USB is that it accommodates a lot, from various Windows and Linux distributions, to repair and rescue tools such as antivirus services or complete live systems or backups. This is made possible by free software tools which, unlike tools such as Rufus, do not create one bootable USB per system, but rather a multiboot USB for various files.
The best-known tools include Yumi, WinSetupFromUSB, and Ventoy. They make a USB multi bootable in a few steps, so that you simply copy desired system files to the stick.
Whether for backups or an emergency solution - every computer user would ideally create data backups in the cloud and on external hard drives and, if possible, have rescue tools, live systems, system backups, and ISO files. These are used when systems need to be reset, or viruses removed. However, this usually requires a collection of live CDs and USBs, which can contain various distributions, additional programs and even BIOS updates. With a multiboot USB, you save yourself a great deal of trouble, because all necessary files end up on a single bootable stick. This gives you the choice between several live distributions and fixes system problems effortlessly.
Creating a multiboot USB is simpler than you’d think. Free tools are available for download online. The prerequisite for a multiboot USB is sufficient storage space - at least 8 GB are recommended here. To make a USB bootable, you must format it first. So make sure that there is no important data on the USB stick. Another advantage: With enough memory, you can continue to store files and documents on your USB stick in addition to the multiboot area.
Multiboot system backups are only one of many backup solutions. Additionally use MyDefender from IONOS and rely on automated backups in ISO certified, secure data centers.
If you want to create a multiboot USB, you’re in luck. Software that creates a multi bootable USB is plentiful and each offers its own advantages. Especially for inexperienced users, setting up multiboot USBs manually is complicated. Since the method behind each of the tools is similar, the example of the tool YUMI (‘Your Universal Multiboot Installer’) will be used here to explain how to set up multiple live systems, installations, or repair/diagnostic tools on a USB.
Yumi formats the USB and provides a comprehensive selection of distributions, including Linux variations such as Ubuntu, Debian Live, Linux Mint, and Fedora for download. In addition, YUMI writes maintenance and diagnostic tools from antivirus manufacturers as well as ISO files from Windows to the stick as required. Prerequisites for YUMI are Windows systems from VISTA and higher or Wine under Mac and Linux. The BIOS should additionally allow booting from USB media. When formatting the USB, note that FAT32 offers optimal compatibility, while NTFS is suitable for systems with more than 4 GB.
Back up important system data and documents to the HiDrive cloud storage from IONOS and conveniently access your files from any device.
Step 1: Download YUMI for free from a trusted platform or the associated website pendrivelinux.com. The tool is ready for use immediately after the download and doesn’t require installation.
Step 2: Insert the USB you’re going to use and start YUMI.
Step 3: Now select the USB drive under ‘Step 1: Select the Drive Letter of your USB Device’. Make sure it is the correct USB drive, as formatting will erase all existing data.
Step 4: Under ‘Step 2: Select a Distribution to put on (drive)’, select the operating system you want to store on the USB stick. YUMI already offers the most important Linux variants like Ubuntu, Linux Mint, Debian Live, openSUSE, Fedora and many more. The software also offers many other system and maintenance tools that you can save on the stick.
Step 5: If you have selected a distribution (Ubuntu in this example), there are now two possibilities: If the Ubuntu ISO file is already on the computer, go to ‘Browse’ and select the file.
Step 6: If the file is not yet on the computer, check ‘Download Link’ to go to the download page of Ubuntu or the selected distribution. After the download, select the downloaded file under ‘Step 3’ with ‘Browse’. If YUMI does not offer an automatic download, download the files manually from the manufacturer.
Step 7: In ‘Step 4’ you can optionally specify how much free USB space you want to reserve for the selected system to save changes and settings.
Step 8: Before you write the selected system or system tool to the stick, you must format the USB stick. To do this, select the appropriate file system - NTFS or Fat32 - and make sure that there are no important files on the stick. Then click on ‘Create’ to create the multiboot USB stick.
Step 9: YUMI will finally list the upcoming changes for you. Click ‘Yes’. The process may now take a few seconds or a few minutes, depending on the stick.
Step 10: Your USB stick is only multibootable if you store further system files or tools on the stick. YUMI therefore gives you the option to write further ISO files or tools directly to the stick.
Step 11: Now select the installer for Windows 10, for example, by selecting ‘Single Windows Vista/7/8/10 Installer’ and, if the ISO is already on the computer, click ‘Browse’. Since Windows ISO files can now only be downloaded via the Windows Media Creation Tool, YUMI for Windows does not offer automatic redirection. Therefore, you must first install the MediaCreationTool and download desired Windows ISO files. After that, select the file in YUMI via ‘Browse’. Be careful not to format the stick after setup, otherwise you will delete existing data.
If you now want to boot your system, you must already connect the USB stick before the computer starts. While the computer then starts, you will see (usually very briefly) an information which key you have to press to enter the boot menu. In most cases this is one of the 12 function keys or the escape key. In the menu you can then select the USB drive and start the boot process. Since you are working with a multiboot USB stick, you then still select the desired operating system and can load the system.
Optical installation media are yesterday’s news. A bootable USB drive is not only faster and more practical than a CD-ROM, it can also do a lot more: For example, create a portable operating system with which you can use Windows as well as Linux computers. The most important function, though, is the ability to boot and repair a PC following a serious system problem. To make such a bootable USB...
For USB sticks to work as storage media, they need to have their own file system. Without this, it can be added manually by formatting the flash drive. Mac users have a tool available for this with the “Disk Utility” program. Read this tutorial article to find out what the individual steps are and which file systems are available to use.
When you want to create backups of important files or copy data to another device, external storage devices like USB sticks continue to be the best solution. But what if some files are only stored on the data medium and the USB drive is not recognised? We point out the most common causes for a “USB device not recognised” message and present the best solutions for Windows and Mac.
File systems like NTFS or FAT don’t just play a key role in computers. Portable storage media like USB sticks also depend on these technologies for organising data, in order to store and process files. If a system is missing or damaged, it can be added or repaired at any time by formatting the USB drive. But how exactly does this work?
