I'm trying to make a bootable usb stick. It says "open the dash and search for startup disk creator". What is the "dash"? and where is it?

This may be a stupid or trivial question, but I am new to Ubuntu, and have two unsolved problems (flashplayer doesn't play, and scanner doesn't work - in virgin install 13.04), so I started to search in documentation. In the 13.04 specific web site I was browsing the hardware section, and came across something like this: "Open Dash, and select Disk Utilities".  So what is Dash, and where is Disk Utilities?  The application finder could not find any of those. In terminal the "dash" command seems to invoke some sort of a shell.

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 have a chromebook series 5. I want to install Ubuntu onto a USB stick. When I downloaded Ubuntu onto my USB stick, it won't start up.  Do I first have to download Ubuntu onto my chromebook hard drive, open Ubuntu and then make USB stick bootable? And then return back to chrome?  Or is there a way to download directly onto USB and make the stick bootable?  I appreciate any help.

I want a complete guide to make a generic multiboot USB. Requests:  Multiple iso boots; Multiple persistent boots (unlimited size); One partition to data storage;  What I've tried:  only lets 1 persistent ISO.  limits your persistent storage to 4GB, no partition for data (still good) mkusb More than 4GB persistent storage, data partition, but single boot. Correct me if I'm wrong. What can be done so far is accepted.

How would I go about creating a CentOS 7 bootable USB drive with Windows? I've read  and it says that Unetbootin and Universal USB installer won't work for CentOS 7. In addition, I've already tried dd for Windows, and that didn't work properly either - booting from the USB drive resulted in a "Machine Check Error".

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 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.

Not a COM32R image boot   is a message that the console infinitely keeps spitting out when I try to install Ubuntu 10.04 from a USB. I created the USB using the StartupDiskCreator in 11.04.  What is the reason for this behavior? What do I do to set it right?   I have followed the steps perfectly, as enlisted in the .

I made a bootable USB drive of the downloadable Ubuntu 16.10, ran, and installed from it.  Fine.  Now after making some stock additions (like Samba, Wine, and such) I'd like to make a USB bootable copy of my particular Ubuntu.  It's still plenty small enough to fit on a stick.  Can it be done?

Does anyone have a Terminal command-line recipe for making a new bootable USB flash drive for one of the new MacBook Air's?  Is there a way to dd copy the USB boot device that comes in the box and make the new copy bootable?  I'd like to make a new backup copy of the USB rescue device for my MBA, preferably on a much larger flash drive with room for a backup of some of my working directories.  Added:  And is it possible to make, not just a rescue drive, but a bootable USB drive that will boot a fully updated version of the OS (say 10.6.8 or later)?  If so how on a MacBook Air 11, and how big a USB stick will this require?

I have a Asus Transformer Book T101HA and I am trying to  boot a bootable USB stick to dual boot a 2nd operating system (it is currently running Windows 10 as it was out of the box).  When I press ESC on start up to load the boot menu, I only get the following regardless of whether a bootable USB is plugged in or not.    I have also looked in the BIOS to look at the boot order but the options look very limited compared to others ive seen in the past. There is only on boot option and it can only be set to 'Windows Boot Manager' or 'Disabled' (there is no option for USB). There doesn't appear to be any ability to add new boot options.    Can anybody help me out with a way forward to booting from a USB?

When you want to create a bootable usb memory stick, then you must identify as a sudoer. Why is that? I have no difficulty understanding why unprivileged users shouldn't be allowed to fiddle with the installed system, but why shouldn't you be allowed to copy grub onto the memory stick if you have write access to it?

We downloaded Ubuntu here  just as prompted. The 64 bit.    We followed howtoubuntu perfectly, using Rufus to put Ubuntu on a new usb stick.   We installed Ubuntu. Everything looked perfect, step by step.   The computer prompted us to restart, so we did.   With the usb stick in, we are prompted to install Ubuntu. Or one time, it started and looked like we were good to go but nothing would open. But when we try to reinstall, we are told the computer already has ubuntu, would we like to install alongside?   Without the usb stick, we are told to install an operating system. "Boot device not found"  You can probably tell by my vernacular that I am not familiar with this process. How can I fix this? Just want to run Ubuntu on the laptop.   Thanks, Tabitha   Edit: this is an hp pavilion laptop, which I could probably tell you more about if I hadn't just deleted everything on it in a failed attempt to use Ubuntu.

I have an ISO image of my backup solution's recovery cd. When I burn the image to a CD-ROM, I can boot from it in UEFI or normal mode without problems.   Unfortunately, this is no solution for my laptop, as it does not have an optical drive. Thus,  I tried to create a bootable USB stick that can also boot in UEFI mode, but so far I have not been successful (note that the laptop has UEFI and boots Windows 7 in UEFI mode).  So my question is, if anyone knows how I can get said ISO on my USB stick so that it boots as if I would use a CD-ROM?

I had Ubuntu 12.04 Beta installed on my computer. When 12.04 was finally released, I made a bootable USB Flash Drive using Startup Disk Creator.  Then I decided to check if this drive works properly and to reinstall the system on my desktop. I must add, my desktop behaves a bit strange when it comes to bootable USB's, it recognizes them as HDD.  In BIOS I changed priority of boot so USB Flash Drive (recognized as HDD) was first. Successfully booted, I installed Ubuntu. Everything worked fine, but...  Now I cannot boot from my real HDD. Every time I want to boot, I put the USB Flash Drive into my computer, boot, safely remove it and everything works.  What do I need to do to repair boot?

The question is simple and straight forward:  How to boot from an USB drive in VirtualBox?  EDIT:  I have attached usb to VirtualBox as shown in the screenshot.    But it is not possible to boot from an USB drive even when attached  .  So I would like to know if there is any other possiblity to boot from an USB drive?
