live-usb interview questions
Top live-usb frequently asked interview questions
I often have a number of Live CDs sitting around (actually USBs) and I'm not always sure which version is which. Is there some quick way to find out the Ubuntu version I'm looking at? Perhaps a file I can look at on the CD, or some executable I can run or something?

I downloaded Ubuntu 14.04 (64 bit) lts. I made a bootable usb stick. But I keep receiving this error message upon booting:
SYSLINUX 4.04 EDD 20110518 Copyright (C) 1994-2011 H. Peter Anvin et al
Unknown keyword in configuration file: gfxboot.c32: not a COM32R image

Is there any way to create a bootable Ubuntu USB flash drive from the terminal without using any third-party applications like YUMI,Unetbootin, 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 create files on the USB disk, but when I try to boot the USB disk it shows a Operating System Not Found error.

Having live media that can boot both ways can be a problem when installing Ubuntu onto currently available Windows 8 computers.
In other words the key advantage to creating UEFI-only bootable USB live media is: You know that it definitely booted and installed via UEFI.
Since Valve has already been doing UEFI-only booting USB installers with their Debian-based Steam OS and UNetbootin — the top voted alternative to Ubuntu's Startup Disk Creator — isn't UEFI compatible and therefore misleading, I think we should have a separate topic for creating UEFI-only bootable USB live media.

What I want is to create a bootable pen drive that shows GRUB menu and I can select any of the several bootable systems from there to install/run. I have several ISO images that I want to install in the USB like Ubuntu, Fedora, System Rescue CD, Windows XP and Windows 7 (The windows versions are optional, mostly am looking for a multi installer for Linux distros, specially Ubuntu version)
The default Startup Disk Creator only works with Linux Images and only 1 at a time (At least for the mean time. If it allows more systems and multiple ISOs it would be awesome)
What method exists that I can use step by step to create a bootable USB Drive with multiple images than can be booted from the USB and selected from GRUB. It must support Windows Images and Linux Images.
Alternative, is there also a way to have multiple versions of the Ubuntu installation ISO on an USB Drive, such as, when booting from it, I get to choose what Ubuntu version and architecture to install, for example:
BOOT MENU
Ubuntu 12.04 32 Bit
Ubuntu 12.04 64 Bit
Ubuntu 12.10 32 Bit
Ubuntu 12.10 64 Bit

I'm trying to install Ubuntu 15.10 32bits on a Samsung NP-N150-JP05FR, with a live usb created with usb-creator-gtk (from ubuntu 15.10, as superuser) on a FAT32 usb flash drive and get this error :
SYSLINUX 6.03 EDD 20150813 Copyright (C) 1994-2012 H. Peter Anvin et al
Boot Error
Any key pressed make that message repeat.
I often install ubuntu with live usb, using either usb-creator-gtk or UNetbootin. I actually already installed ubuntu (14.04) on that computer a few months ago. I can't figure out the issue.
Already tried :
- different USB flash drives
- checking .iso integrity
- renaming
isolinux files to syslinux
- checking for
USB Mass Storage Emulation type option in Bios (no such)
UNetbootin instead of usb-creator-gtk- removing "
ui" from syslinux.cfg

I have Fedora installed on my desktop and I want to make a live USB stick with Ubuntu to install it on a laptop. What's the easiest way to do it?

I'm trying to install Ubuntu 12.04 Server (32bit) on a machine here using a USB stick. I used the Universal-USB-Installer-1.8.9.4 which has support for 12.04 server to get the ISO onto the USB drive.
- The computer boots up the installation process ok.
- It gets through the Ubuntu language, locale and keyboard selection.
- Then starts loading additional components. At this point it gets about a quarter of the way through then throws big error message saying:
[!!] Load installer components from CD
There was a problem reading data from the CD-ROM. Please make sure it
is in the drive. If retrying does not work., you should check the
integrity of your CD-ROM.
Failed to copy file from CD-ROM. Retry?
Retrying obviously fails as well. Have tried re-running again and installing again onto the USB but no change. Have tried checking for CD-ROM integrity errors and it breaks on this error:
[!] Check the CD-ROM(s) integrity
Integrity test failed
The
./pool/main/l/linux/fs-secondary-modules-3.2.0-23-generic-pae-di_3.2.0-23.36_i386.
file failed the MD5 checksum verification. Your CD-ROM or this file
may have been corrupted.
Have also tried the Ubuntu-Server 12.04 LTS (Precise Pangolin) daily build. No go there. Even checked the iso SHA1 hashes and they match.
Have tried LinuxLive USB Creator 2.8.11 and unetbootin-windows-575 to see if it was an image with the USB drive software but still no go.
Any ideas?

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

I want to make a persistent live Ubuntu/ Mint usb drive with more than 4gb of storage. I know there is an option of installing linux directly on the drive but I dont want to do this as it will restrict the drive from working on different computers. One options is to make an additional partition with extra space but if i do this how do I make newly installed software be stored on this partition?
Thanks!

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 (reference).
So I would like to know if there is any other possiblity to boot from an USB drive?

This has been asked several times already (I found it here, here and here), but basically everyone simply recommend to perform a full install to the USB stick. But I do need it to stay as a LIVE session, not a "full install on USB", for a number of reasons (the most important one being that using Live session I can easily install Ubuntu using the desktop icon)
So, my constraints for skipping the Welcome Screen (and automatically choose "Try Ubuntu" option) are:
It must actually be the Ubuntu Live session (or as close to the default as possible). Same software selection (gparted is present in live sessions, gimp is not, for example), user (name and ID), behavior (no login screen, no password for sudo, to name a few), no GRUB, etc. That rules out an Ubuntu full install on USB.
It must be able to install Ubuntu in the computer (while full install requires the ISO file, an additional USB stick, and the hassle of Startup Disk Creator)
If possible, to be as fast as the "text-based launcher" (the one you have when you press a key right after the kernel loads)
It must be completely automatic, unattended from boot to desktop.
Select a different language than default. It can be a hard-corded selection (actually, it must, since boot itself shall be fully unattended). But preferably be easily changed ("easily" as in editing a config file then rebooting)
Is it possible?
The proposed (great) solutions that I've ruled out so far are:
Installing Ubuntu in the USB stick (for all of the above mentioned reasons)
Remove Ubiquity package (it removes the ability to install the system from that USB as well)
Ubuntu Customization Kit (ubk): several limitations and caveats, and its not even in the repos
Remastersys / LiLi: its the same as full direct USB install, only customized.
An ideal solution would be something like "create USB sick using Startup Disk Creator, then open it and remove / edit / add file(s) xxx, yyy, zzz"

I created an Ubuntu 10.10 live usb with persistence feature. And it works well on my PCs. But one thing annoys me is that each time I boot from live usb, I have to choose between "Try Ubuntu" and "Install Ubuntu". Is there any way to dismiss that dialog and boot directly to the live Ubuntu system?
