Universal USB Installer – Boot from USB

Universal USB Installer aka UUI is a Live Linux Bootable USB Software. This tool allows users to easily Boot from USB. Make a USB Boot from a Live Linux distribution, Windows Installer, Windows To Go, Antivirus Scanner, Disk Cloning Software or any other System Tool that can be put on a flash drive. The software is easy 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 Bootable Flash Drive containing the operating system or tool you selected.

Unlike tools which simply use the DD (Copy and Convert) command to directly Burn ISO to USB, the Universal USB Installer includes several other methods that natively allow you to continue using your flash drive 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 USB device appear as a CD/DVD which is limited to the size of the ISO file. However, it may be possible to Recover Lost USB flash drive space and then create an exFAT partition for continued storage purposes. Another key feature of UUI is Persistence storage, where available. This Persistent 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. A larger than 4GB casper-rw or persistent option is also possible when the USB drive is formatted with an NTFS filesystem.

NOTE: If you are wanting to add multiple Live Linux Distributions, System Diagnostic Tools, Antivirus Utilities, and Windows Installers, you should use the YUMI Multiboot USB Software, instead. It can help you Boot Multiple ISO files from one flash drive.

25 Nov 2021 Universal-USB-Installer- Fixed to allow spaces in Windows user profile.


Requirements to Create a Live Bootable USB Flash Drive

IMPORTANT: UUI only shows USB drives detected by Windows as removable media. See the best recommended Fast Flash Drives.

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 USB.
  • Windows 11, 10, 8, 7 Operating System to run UUI.
  • Greater than 2GB *Fat32 or NTFS Formatted Flash Drive. MBR partition table.
  • Computer with a BIOS that can boot from USB.
  • Your Favorite Linux ISO File.

Feel free to inform me of unlisted Live Linux distributions or version revisions, and I will do my best to update the UUI tool to support them.

Universal USB Installer Troubleshooting, Issues, Bugs

The Windows to Go option does require the USB 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 USB 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 USB drive 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 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 USB drive may be improperly formatted, contains more than one partition or MBR, or your BIOS is not properly detecting the USB drive. In which case your firmware probably needs to be updated. You can also try to Format and Restore a USB 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 your USB drive 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 flash drive, reformat it. Then try again to see if your BIOS can detect and boot from it.


  • If you’re running a Windows Vista or 7 Installer from your USB, after the first reboot, remove the flash 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 Universal USB Installer from the same directory containing an installable ISO, the UUI 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 formatted USB, Ubuntu based “persistence” features will only work with a Fat16 or Fat32 formatted drive. Additionally some Linux Distributions will not boot from an NTFS formatted USB.

Again, Universal USB Installer does not support booting from multiple Linux distributions. Only one distribution can be installed per USB drive. However the YUMI Multiboot USB Creator 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. I plan to revisit this issue when I find the time.
