![]() Instead of relaunching this Live Linux USB Creator to add more distributions, you can simply drag additional ISO, IMG, WIM, VHD(x), VDI.vtoy, and EFI files from any folder on your computer and drop them onto any folder under the UUI folder on your flash drive. Supports the ability to Drag and Drop ISO files to the USB drive Drag and Drop ISO Files onto USBĭrag and Drop ISO to USB functionality is supported so long as you don't need persistence, and do not need the tool to keep track of your installs for possible removal at a later point. Currently supporting up to 40GB persistence. Starting with version 2.0.1.6, the USB drive is formatted with an exFAT filesystem, so an option to use a larger than 4GB casper-rw or live-rw persistent block file, (also known as an overlay image) is now possible. Ubuntu based Casper persistence works with FAT32, NTFS, or exFAT formatted drives. This persistence feature allows you to save changes and then restore those changes on subsequent boots. Persistence feature for saving changesĪnother key feature of this bootable USB maker is the use of persistent storage, where available. This method allows your USB drive to appear to Windows as a regular exFAT formatted flash drive and enables you to continue using your removable device for traditional storage purposes. UUI offers a more practical method than DD through the use of an exFAT partition for storing bootable ISO files and block images, along with a separate hidden secondary FAT boot partition which is used to boot those files. However, if the filesystem used by the CD/DVD image supports expansion, it may be possible to recover lost USB drive space or storage capacity by extending the space and creating another partition to use for storage. This process causes the drive to appear limited to the size of the chosen ISO file which can prevent you from continuing to use the drive for storage purposes. The DD method of copying, also commonly referred to as "Data Destroyer" works by overwriting the entire file system on a flash drive with that of a CD or DVD image. Some boot from USB tools use simple DD (Disk/Data Duplicator) copy and convert commands to directly burn ISO to USB. Universal USB Installer easy as 123 - Showing ISO to USB File Copying Progress Once finished, you should have a ready to run Live USB containing the Live operating system, Windows installer, or system diagnostics utility, or advanced system cleaner tool you previously selected. Simply select your target flash drive, choose your distribution from the list, browse to the ISO file (or choose to download the ISO), and then click Create. Using this open source USB boot maker software is easy as 123. ![]() Universal USB Installer | Easily Make a Bootable USB UUI - Universal USB Installer software - create bootable USB from ISO You can even use UUI to fully install, boot, and run Windows entirely from USB. The most popular antivirus scanners, disk cloning software, penetration testing, and system diagnostic tools can be stored on and configured to boot from the same single multisystem bootable pendrive. Take all your favorite Live Linux distributions, Windows Installers, system recovery, backup, and diagnostic tools with you, capable of booting from one USB drive. This ISO to USB utility allows you to easily create a bootable USB from ISO files, enabling you to boot from USB into Windows, Linux, and system tools. But if you do not choose DD mode, you are undoing any signature verification that you previously performed and introducing a potential vector into downloading a malicious bootloader for the installer.The Universal USB Installer (Imager), also known as UUI, is bootable pendrive software. On the positive side, it allows you to put other files on the USB drive, whereas DD mode makes the USB drive read-only, as it uses the ISO9660 read-only file system.ĭon’t worry about downloading the files, because DD mode does not use them. As the Qubes installer is signed over the whole qubes.iso file, there would be no way to verify the files that are written to the USB drive match what was in qubes.iso. The files that it is asking to download are part of that process/bootloader. ![]() It installs its own bootloader, reformats and partitions the USB drive, then copies files within the qubes.iso file to the USB drive. You want this, because hopefully you’ve already verified the PGP signature of the qubes.iso file, and this will ensure what is written to the disk matches what has been verified. Every byte starting from byte 0 of the USB drive will match your qubes.iso file. When selecting DD mode, Rufus is doing a byte-for-byte copy of the qubes.iso file to the USB drive. You can say yes to download the files if it does not allow you to go further, but those files are not used if you select DD mode.
