Universal USB Installer - Boot from USB

Universal USB Installer (Imager) aka UUI is a Live Linux Bootable USB Creator Software. This ISO to USB imaging tool allows users to easily Boot from USB. Make a flash drive boot from a Live Linux distribution, Windows Installer, or fully install Windows onto USB using Windows to Go methods. Popular antivirus scanners, disk cloning software, penetration testing, or other system tools can also easily be made to boot and run from the removable media.

The software is as easy as 1,2,3 to use. Simply choose your distribution from the list, browse to the ISO file, select your target flash drive, and then click Create. Once finished, you should have a ready to run Live USB containing the Live Operating System, Windows Installer, or System Diagnostics utility you previously selected.

Unlike tools which simply use DD (Copy and Convert) commands to directly burn ISO to USB, UUI includes several other methods that natively allow you to continue using your removable device for storage purposes, whilst including a "Try via DD" option. The DD method of copying, also known as Data Destroyer works by overwriting the entire file system, making the device appear as a CD/DVD which is limited to the size of the ISO file. However, it may be possible to recover lost drive space and then create an exFAT partition for continued storage purposes.

Another key feature of UUI is the use of persistent storage, where available. This persistence feature allows you to save some changes and then restore them on subsequent boots. Ubuntu based Casper persistence works with FAT32 or NTFS formatted drives. An option to use a larger than 4GB casper-rw or live-rw persistent block file, (also known as an overlay image) is possible when the drive is formatted with an NTFS filesystem.

NOTE: If you are looking to add multiple Live Linux distributions, System Diagnostic Tools, Antivirus Utilities, and Windows Installers, you should use YUMI Multiboot Software to boot from USB, instead. As a multisystem tool can help you Boot Multiple ISO files from one flash drive.

30 Apr 2023 Universal-USB-Installer- Fix broken persistence option for Ubuntu and Linux Mint based distributions. Show format option for selectable drives that appear as USB drives or local disks.
Note: The persistence feature currently only works on fat32 formatted drives.


Requirements to Create a Live Bootable USB flash drive

IMPORTANT: UUI will show drives detected by Windows as either removable media (USB Drive) or a fixed (Local Disk). See my personal list of the best recommended fast SSD flash drives to use with this UUI tool.

Your flash drive must be Fat32/NTFS formatted, otherwise Syslinux will fail to install an MBR (Master Boot Record), and as a result the device will NOT Boot.
Additionally, the Windows to Go option requires an NTFS formatted device with 20GB free disk space to hold the virtual disk. See FAQ for more info.

  • Universal-USB-Installer- to make the bootable drive.
  • Windows 11, 10, 8, 7 Operating System or WINE.
  • Greater than 2GB *Fat32 or NTFS formatted flash drive. MBR partition table.
  • Computer with a system BIOS that can boot from USB.
  • Your Favorite Windows or Linux ISO File.

Feel free to let me know about any unlisted Live Linux distributions that should be included or version revisions, and I will do my best to update the UUI tool to support them.

Troubleshooting, Issues, Bugs

The Windows to Go option does require the drive be NTFS formatted and have 20GB+ free space to hold the virtual disk. Most of the flash drives found at local department stores won't be fast enough. You will need a very fast solid state flash drive. When Windows boots from the pendrive for the first time, it will go through the setup process and then reboot. You will need to boot using your Windows to Go flash drive a second time to finalize the setup process. And then finally boot into your full Portable Windows.

The tool expects the Volume Label of your device to be UUI in order for OpenSUSE, CentOS and a few other distributions to boot. It does attempt to automatically create this Label, but may fail. So make sure it remains UUI in order to allow those distributions to boot.

Persistence feature is currently broken with Newer Debian based distributions. This is due to upstream changes. In that Debian now requires a rename of the persistent block file and label from live-rw to persistence . In addition, it must house a persistence.conf file containing the text / Union. I plan to make all of the necessary changes and then provide a fix as time allows.

If you're using UUI Universal-USB-Installer- and you still receive Insane primary (MBR) partition notices,

Insane primary (MBR) partition. Can’t find myself on the drive I booted from

Your flash drive may be improperly formatted, contains more than one partition or MBR, or your BIOS is not properly detecting the device. In which case your firmware probably needs to be updated. You can also try to Restore and recover a flash drive.

An Error (1) occurred while executing syslinux

If you encounter a message stating;

An error (1) occurred while executing syslinux. Your USB drive won't be bootable.

An error (1) occurred executing syslinux

The most likely cause is that the device is formatted as exFAT or some other unsupported format. You'll need to reformat as fat32 (currently preferred) or NTFS.

My PC wont Boot from my flash drive, but supports USB boot!

Older flash drives shipped USB-FDD formatted and some systems will not boot USB-FDD. However, I have found that most systems can boot USB-ZIP, and or USB-HDD. If you are having a hard time getting your BIOS to detect your drive, reformat it. Then try again to see if your BIOS can detect and boot from it.

Other Important Notes:

  • If you are running a Windows Vista or 7 Installer from your thumb drive, after the first reboot, remove the thumb drive and let the pc complete from the hard disk.
  • When browsing for an ISO, UUI will only display ISO Files that match what the tool is asking for. For example, if you chose to install ubuntu-20.10- Desktop-i386, the tool might not display your ubuntu-20.10-Server-i386.iso because you have not selected the server variant. However, you can force all ISO files to be shown by clicking the Show All ISOs box.

Auto Detection: If you also run UUI from the same directory containing an installable ISO, the script will auto detect the ISO and bypass step 2.

Universal USB Installer auto detection of ISO in same folder

* Although you can use an NTFS format, Ubuntu based "persistence" features will only work with a Fat16 or Fat32 formatted drives. In addition, some Linux distributions will not boot if the drive is NTFS formatted.

Again, UUI does not support booting from multiple Live Linux distros. Only one distribution can be installed per drive. However the YUMI Multiboot Creator Tool can be used to create a Multi System USB boot device.

To try an ISO that isn't listed, simply choose one of the the last three options in Step 1. I recommend "Try Unlisted Linux ISO (GRUB)" because it seems to be the most successful. Feel free to inform me of unlisted "Linux ISOs" you get to work via these options, so I can add them to the supported list.

OpenSUSE DVD and other ISOs with a single file that exceed 4GB will not work due to the Fat32 file size limitation.

The Universal USB Installer will NOT currently work from within Linux using WINE due to drive detection and privilege issues. The tool mentions this when running UUI from Linux and WINE is detected. I plan to revisit this issue and will hopefully implement a better solution when I can find some spare time.
