az of parameter, the name of the block device on our flash drive, not its partition.īe careful not to misspell here, as it will be overwritten by another incorrectly specified container.Navigate to the directory of your ISO file you want to burn, then rootrun as: dd if=debian-9.5.0-amd64-netinst.iso of=/dev/sdc bs=4M sync I/O size (minimum/optimal): 512 bytes / 512 bytesĭevice Boot Start End Sectors Size Id Type Sector size (logical/physical): 512 bytes / 512 bytes The output should look for something like a flash drive:ĭisk /dev/sdc: 7,5 GiB, 8011120640 bytes, 15646720 sectors The command lists all the hard disks and USB devices in the machine and their logical units. Of course, from UNetbootin we can already know how to access the device on our flash drive, but here we need to determine it anyway. Discovering a pen driveįirst, insert a flash drive into the machine, and then run the fdisk command as root to find the device on the flash drive block: fdisk -l I will use the Debian 9.5 netinstall used in the UNetbootin example above to illustrate this. Non-isohybrid ISO files are isohybrid can be converted to start with the dd command. Examples include installation images downloaded from Debian sites, but other installers could have been created using this method. It should be noted here that only a isohybrid ISO files created in this way will be able to boot. In this example, dd Linux command we will use it for this purpose. If for some reason UNetbootin does not start up or is not working properly, we still have another quick option to make a bootable flash drive. Print the boot image using the dd command So if you leave other materials on the drive in a subdirectory, they will remain intact. One thing to note about this is that there is no formatting here, so the previous contents of the flash drive will be retained, except for conflicting files, directories. This will copy the ISO files and the boot loader:įinally, you will be notified of the completion of the operation and instructions on how to start the flash drive: Then, if there was something on the flash drive that might conflict with the content you are now uploading, it will throw another window: Select the drive from the drop-down list: It should be noted here that (probably) because of a malfunctioning of the program, accessing the image file is only possible in / Root works under a directory structure, so you can only browse files from this directory.Īccordingly, I copied a freshly downloaded Debian netinstall to / Root library, which is small, so perfect for this presentation.įrom here on, both options continue in the same way:
