Ive been having problems doing a Ubuntu install () and think it may be the USB stick was not written properly.  How can I write and verify the image (was using windows to do this but do have another Linux box I can use to make the USB). I know there is a verify in the installation menu but would rather do it manualy (i.e. with CLI).

Is there a way to perform an integrity check on a ready-to-use USB boot disk?  I just made a Lubuntu 14.04.01 boot USB, and have not been able to figure out how to run an integrity check on it.  I can't find any .iso file to run an MD5sum hash against.

I work at an embedded software company. This morning I found a USB stick in the parking lot in front of the building. With all the stories of "dropped USB stick attacks" in mind, I'm obviously not going to just plug it into my laptop. OTOH, I'm curious to know whether this was actually an attempt to compromise our systems, or it's really just an innocent case of somebody accidentally losing a USB stick. How do I safely inspect the USB stick without risking exposure?  I'm worried not just about malware and crafted file system images; there's also stuff like power surge attacks:.  EDIT: Many of the answers seem to assume I want to keep the drive and use it afterwards. I have no interest in that at all, I know USB sticks are cheap, and that it wouldn't be mine to keep anyway. I only want to know whether this was indeed a semi-targeted attack, partly out of curiosity whether this actually happens in real life and not just in security papers, but also so that I could warn my coworkers.  I want to know how I would figure out whether the stick contains malware. And that's not just a matter of looking at the drive contents and seeing a suspicious autorun.inf or a carefully crafted corrupt file system - I very much also want a way to inspect the firmware. I sort-of expected that there were tools for extracting that and comparing to known-good or known-bad binaries.

I have a USB-stick (used as an installation medium). Now I need to install a driver from a restricted folder on that device). But how do I get the device path to my USB-stick (e.g. /dev/sda3 so I can mount it using the mount command?  I have read the answer to  but fdisk -l shows nothing to me.

I'm trying to create a Windows 7 installation USB (for use on a PC) from OS X.  I've tried following these instructions from a :   Insert the USB flash drive and run the command diskutil list to find out the disk name, we'll use /dev/disk1 as an example Now unmount the disk using diskutil unmountDisk /dev/disk1 dd if=/path/to/Win7.iso of=/dev/disk1 bs=8192   But the instructions don't work. When I insert the created USB drive into my PC and try to boot from it, I get this message:     Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key   What am I missing?

I am looking to create a USB flash drive that I can put multiple  ISO images on and select which boots from startup. The ideal candidate supports Linux and Windows-based ISO images, and is relatively simple. It also must have some reasonable process for adding and removing an ISO image from the drive/list.    Things that I'm not looking for in this specific question:    or other swiss-army knife live CDs. The point is to boot any one of multiple CDs, not to boot a (certainly useful) utility CD. Installing a single live CD to a USB drive. I'd like to have multiple ISO images, selectable at startup.   I don't have a specific purpose in mind, possibilties include a single drive with a  variant, Ubuntu desktop, UBCD4Win for DOS, the Offline NT Password Cracker, etc.  Flexible and easy to use are the name of the game!

After considerable review of the options, I tried and failed to create a usable live Ubuntu USB with persistent storage using what seemed like "best practice" instructions at  I suspect I'm one step away from a full solution, but I need help.  I reviewed answers on AskUbuntu and other places before starting, including many responses by @C.S.Cameron and @sudodus. Answers for OS versions earlier than 18.04 are now of uncertain value for running 18.04 or later due to various issues. Hence I opted to follow the comprehensive and recent instructions at the URL above.   After following the instructions, I seem to have a USB drive formatted by mkusb as predicted. When I attempt to boot, the BIOS/UEFI process identifies the USB stick as a possible boot location, but when I select it for booting and proceed, I am returned to the same screen for choosing a boot location. For some reason, the USB stick is rejected as a viable boot option. I have tried the process 3-4 times using 2 iso images (18.04LTS and 19.10) and 2 USB sticks (Sandisk Extreme 64GB and Sandisk Cruzer Facet 16GB). Below are links to two screenshots of GParted analysis of the resulting USB sticks.

I'd like to create an Ubuntu live USB stick on a Mac to use to install Ubuntu on another machine. How do I accomplish this?

I am a newbie to all of this stuff.  Initially I had a OS CD of Ubuntu 10.4 version. I never tried to install it. Now I have lost my CD somewhere. Earlier I copied the content to my laptop. When I tried to install by copying to another CD/pendrive it didn't install.  Now i am using Windows. But I would like to install Ubuntu, because everyone said that Linux/Ubuntu is an amazing OS.  So I searched in google for a solution. With Unetbootin, pendrive linux, I can make a bootable pendrive to install. But Unetbootin asks for an ISO-image. I did many experiment and wastes more than 9 CD's. I have no experience with that. Where can I get the ISO-image? Actually, what is an ISO-image?

I'm looking to download and install the latest version of Ubuntu to replace the current version of Windows I had pre-installed on my machine when bought it.   I have some really neat features on the machine that I really am hoping will still work when I move over to Ubuntu.  Can someone please confirm if the below will still work and, if not, how I can get them to work:   The USB ports on my machine The ethernet or Network work port on the machine The HDMI output on the machine and finally, the built in webcam   Thanks Sam

I have created a USB flash drive with the latest Ubuntu version, but it is not persistent. How can I make it persistent without repeating the whole process?

I'm trying to make a Ubuntu live USB, but I have run into some problems:   Used LiveUSB install on my Lubuntu laptop. Breaks USB drive until reformatted, does not boot. Used Startup Disk Creator on Lubuntu. Makes bootable drive, but not persistant storage Used UNetBootin on Lubuntu, puts Ubuntu on USB stick but does not make it bootable Tried to use Universal USB Installer with WINE, but it didn't work. The first time it could only see the floppy disk drive not the USB, the next time it threw an NSIS error. Tried to use Universal USB Installer on Windows, but it needed admin permissions   I have a laptop with Lubuntu installed* (that I have the sudo password for), a Windows 8 desktop without administrator permissions and a 32GB sandisk USB stick. Is there anything else I can do to get it to work?  *IBM T-42 Thinkpad with 1GB ram and an intel Centrio mobile processor that I had to force PAE to get Lubuntu to install if it is relevant.

Downloaded the Ubuntu 16.04.2 .iso install disk and flashed it onto a USB stick.  Booting on the USB stick, there is no memtest86+ option (along with "Try Ubuntu").  Is there a way to add it to the install options?  (it's for a UEFI boot PC running normally Windows, its owner does not want to install Ubuntu. "memtest86+" is completely free (unlike "memtest86"), but is quite old, and does not offer a UEFI boot - this is why having it within the Ubuntu options makes things easier)

I am aware that similar questions have been answered before for different versions/releases of Ubuntu, but I cannot find an application to reformat a USB stick in Kubuntu 12.04.01. Right-clicking the drive in Dolphin doesn't give the format option. Is it possible on software that comes with the package, without resorting to the Terminal or GParted?

Is there any way to create a bootable Ubuntu USB flash drive from the terminal without using any third-party applications like , , ,  etc.  I tried to create a bootable Ubuntu flash drive with dd method,  sudo umount /dev/sdb sudo dd if=/path/to/ubuntu.iso of=/dev/sdb bs=1M   It creates files on the USB disk, but when I try to boot the USB disk it shows an Operating System Not Found error.

I tried to use the usb-creator.exe from Ubuntu 10.10 desktop i386 ISO image and it does create an USB stick that doesn't boot. When I try to boot from it I get:     Operating System not found.   I try to do this from Windows 7 x64. I'm not looking to create a live Ubuntu media, only an installation USB disk.  I repeated the process several times and I even tried to reformat the USB drive (FAT32), no success yet.  The USB stick is a 8GB one.

I'm trying to install a portable app onto my USB drive such that it is compatible with both Ubuntu and Windows (specifically, a program called eToys). Support is already built into the app for both operating systems - there's etoys.sh for Ubuntu and etoys.exe for Windows. I decided to install onto a FAT drive since that can be read from both systems. This works fine for Windows, but for some reason I cannot execute etoys.sh on Ubuntu.  The problem is not with the file - when the whole folder is copied to the local hard drive, the app works great in Ubuntu. But when I try to execute it from the USB, it opens the file in a text editor.  I then tried to run it from a terminal, but I got the message Permission denied.  I've had the same problem with other executables as well.  Is there an easy way to execute things from a USB stick?

I've created an Xubuntu 18.04 persistent live USB stick and installed several softwares for web development, such as XAMPP, Sublime Text 3, Google Chrome, etc.. I did some configurations as well in the ~/.bashrc file.  I am wondering if these installation and configuration in my persistent live USB stick be carried over in a full installation in to a new machine using it.
