I need access to docker which I cannot get on windows because for some reason version 2004 is not yet available for me (I checked for updates in settings) so I am trying to dual boot from usb. I have created a live USB with ubuntu, I made it bootable then tried to boot from usb and it brought up gnu grub. I selected ubuntu and then my PC just keeps powering off while &quot;checking disk&quot;. I now formatted my usb as ext4 and it is no longer visible in my PC so I don't know how to move ubuntu to the USB. Is there a straight forward way to get this done?? It has been a nightmare so far I don't know what to do anymore.

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 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?

I have a problem I have had before. When I create a USB drive to install Ubuntu 12.04 using startup disk creator, it won't work. It doesn't give me any errors, but when I restart the PC to boot into the USB drive (settings are correct in BIOS), I get the option to: 1) Try Live CD 2) Install Ubuntu 12.04 3) Check the disk  I choose option 2 and after that, nothing happens, just black screen no matter how long I wait.  I tried creating the USB using unetbootin, on both Ubuntu 11.10 and Windows 7, but same issue.  I have had this problem installing Ubuntu 11.10 too, but it was solved by creating the USB drive in Linux Mint. But I don't have Mint installed now, so I hope someone knows what the problem could be. Thanks in advance!

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!

I have two systems installed previously Windows 7 and Ubuntu. I was trying to reinstall Ubuntu and format the Ubuntu OS partition using a tool in Windows 7.   When I have Ubuntu ready on a USB stick and restart my laptop, it prompts me with the GRUB rescue screen. If I boot from USB to install Ubuntu, it just hangs.   Anyway, I messed up everything. So my question is how can I boot Windows 7 now?

I want to install Ubuntu and learn Linux.  I've been using Raspbian a bit and really would like to get away from Windows as much as possible.  The only problem is some of the games I use requires Windows for now.  Also, I'm taking classes through Coursera and using online tutorials to learn Linux from and would like an operating system installed besides the Raspbian I have on my Pi.  I have a desktop computer with Windows 10 installed on a SSD (M.2 if it matters) and another HDD used to store files. I have a new 1 TB HDD I'd like to install Ubuntu on. My plan is to install it and place the GRUB bootloader on the new drive.  I can then point the UEFI to that drive as the primary boot drive and GRUB should allow me to choose Linux or Windows. My thought is if I do this, I can change the boot order in UEFI back to C:\ drive and have the machine boot directly to Windows as it does now. Then I have the option of having a dual boot system or a Windows only system. Is this viable?  Should I use the whole drive for Linux?    Also, I'm reading a couple different opinions on disabling Secure Boot and Fast Boot from the UEFI.  Any reason not to disable these in my plan above?  Any other advice is welcome. I appreciate the help!

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?

I'm having a rough time getting Ubuntu to run from a 250 GB USB hard drive.  I booted Ubuntu 9.10 from a CD and ran the regular "install" to the attached USB drive. I used the "advanced" option on the drive partition question to put the boot loader on /dev/sdb (the USB disk) but when I boot the machine it doesn't recognize there's a boot loader on the USB drive (it offers to boot from 2 other devices but not the USB disk).  I also tried booting from the Ubuntu CD and using usb-creator-gtk to set up the USB drive. Seems to me this is meant to work with flash drives. I got a bootable USB disk but it looked and worked like the CD, i.e. it gave me options of "live CD" operation, installing, memtest, etc. That's not the way I want to run the system.  Some help in installing Ubuntu, bootable into a "full" running system on my USB drive would be appreciated.

I want to install Ubuntu on my laptop that doesn't have a CD-ROM drive and I have no spare USB disk. I've tried Wubi, but that doesn't seem to work (since it prompts me to have the CD in the drive, which I don't have).  How can I install Ubuntu, easily and in a fast way?  P.s: I want to dual boot it with Windows 7 (which was preinstalled).  Edit:   When extracting the ISO to a folder and running Wubi it does install, but when I reboot the computer, it doesn't show GRUB, nor can I choose if I want to boot Ubuntu or Windows 7. After trying for the third time today, wubi gives me an error: Permission denied   I'm the administrator on the PC.

I created a live USB using Unetbootin (distribution: ubuntu 12.04 ) from the alternate installation ISO, but while booting "try ubuntu" option is not displayed in Unetbootin menu. Is there any way to try this ubuntu distribution without installing ?

I have a bootable CD image that I would like to transfer to a USB stick, so that I can boot from it. The Startup-Disk creator doesn't support it. How can I make a bootable USB disk from it? The ISO is quite old so that might be a problem.

Basically what I want to do is install a fresh copy of Ubuntu from Ubuntu. It is an older machine so usb boot doesn't work and I don't see why I need to waste a CD to do it. Currently running Ubuntu 11.10.  I have a 1TB drive and a second 500GB drive for backup. The 1TB drive is partitioned as:  20GB   sda1 Windows XP 20GB   sda3 Free for new OS  ~800GB sda4 Data (ext3) 60GB   sda7 /home (ext4) 20GB   sda6 / (ubuntu 11.10 ext4) 2GB    sda5 swap   After researching I decided that using unetbootin was the best option. I chose Hard Disk (frugal install) and the only option for which disk is "/". That worked and I quickly rebooted into Ubuntu 12.04 live.   Chose to install and picked custom options, set sda3 for / and sda7 for /home. The installer started but hit a wall at detecting other operating systems. It was trying to mount sda6 to find out about the existing os's on the machine, for the purpose of installing grub. And it couldn't umount sda6 because that was currently mounted as cd drive for live cd. I couldn't find an option to make the installer skip this step (I could later fix the grub in 11.10).  I have another drive with 4GB free partition and if I could get unetbootin to install to there it would all work.  So my question is - how do I get unetbootin to install to a different disk for hard-disk install? (I don't think USB Drive mode will work because it will install the grub to that disk -  but I might be wrong!)  or  How to fresh install Ubuntu from Ubuntu?

When I tried to boot my PC into Windows 10 I got a screen with a sad face saying unmountable_boot_volume.  After searching it said I needed a Windows 10 USB or CD which I do not have.  I still have access to Kali Linux on my PC by booting up with my SSD.  How can I make a bootable Windows USB with a ISO in Kali Linux OS?

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?

Possible Duplicate:             I know there are a lot of tools to create a bootable usb for ubuntu with windows.  But I'm sure, that there was a possibility in the ubuntu installation directory. I used it some time ago, but I can't find it anymore :(  I think it was a .exe, or a .bat, any case a cmd window has opened, some things were executing and the usb was bootable. And it was in the ubuntu directory!  Is there still the possibility to do that? Does that file exist? I unfortunately can't remember.
