## page was renamed from Installation/FromUSBStick/tmp ||<>|| = Outline = The general procedure to install Ubuntu (or Ubuntu flavour, Kubuntu, Lubuntu, Xubuntu, ...) from a USB flash drive is: * Get the correct Ubuntu installation file, 'the iso file', [[https://ubuntu.com/download|via this link]] or Ubuntu flavour [[http://releases.ubuntu.com/|via this link]]. Download the iso file into your running computer (for example into the directory '''Downloads''' in the internal drive, '''not''' into the USB flash drive that you want to make into a USB boot drive). * [[https://help.ubuntu.com/community/UbuntuHashes|Check with sha256sum (or another checksum tool) that the download was good]]. * Put Ubuntu onto your USB flash drive alias 'stick' alias 'pendrive' alias 'thumb'. Tools for this purpose are described in this help page. * Configure your computer to boot from USB flash drive and boot from it. * [[http://ubuntuforums.org/showthread.php?t=2230389|Try Ubuntu (Kubuntu, Lubuntu, Xubuntu, ...) before installing it.]] * Install Ubuntu to your internal drive (hard disk drive or solid state drive or external drive). See also: '''[[https://help.ubuntu.com/community/Installation/FromUSBStickQuick|Installation/FromUSBStickQuick]] for beginners starting from Windows.''' = Introduction = Ubuntu can be installed from a USB flash drive. This may be necessary for most new portable computers without DVD drives and is handy for others because a USB flash drive is so convenient. Also, you can configure Ubuntu on the USB flash drive to save changes you make, unlike a read-only CD/DVD disk. Booting from a USB flash drive created with '''usb-creator''' alias '''Startup Disk Creator''' and '''mkusb''' will behave just as if you had booted from the install CD. It will show the language selection and then the install menu, from which you can install Ubuntu onto the computer's hard drive or launch the LiveCD environment. Other utilities, e.g. '''UNetbootin''', may create slightly different boot drives or if on UEFI might not work at all with Debian iso files [[https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=775689|due to a bug]] Note: This article uses the term "USB flash drive" alongside USB stick, USB drive, USB device, USB pendrive and thumb drive. = Prerequisites = To create a USB installation device, you will need: * an '''8 GB USB flash device/drive/stick'''. If the iso file is smaller than 4 GB, it is possible to use a 4 GB USB device, at least with some of the methods. Files on this USB device will be erased, so '''backup the files you want to keep before making the device bootable'''. Some of the tools require that this USB device is properly formatted and mounted while other tools will overwrite whatever is on the target device. Please follow the instructions for each tool. * an '''Ubuntu flavour ISO file''' downloaded from an official web page, [[https://ubuntu.com/download|ubuntu.com/download]] or [[http://releases.ubuntu.com]], stored in your running computer (for example in the directory '''Downloads''' in the internal drive, '''not''' in the USB flash drive that you want to make into a USB boot drive). * [[https://help.ubuntu.com/community/UbuntuHashes|Check with sha256sum]] (or another checksum tool) that the download was good. In Linux there is the tool 'sha256sum'. In Windows you can do it with Rufus: [[attachment:/fromWindows/rufus-md5sum.png|click on the circle with a tick mark]] (more about Rufus [[/fromWindows|here]].) == Dummy headlines == After a major remake of this help page the following headlines are kept here because they may be linked to from other web sites.

Xubuntu). * Use another tool (e.g. 'UNetbootin' or 'mkusb'), if you want to create a USB boot drive with another Linux distro (alias Linux operating system). You can find '''usb-creator-gtk''' by typing "Startup Disk Creator" (Ubuntu Desktop) or '''usb-creator-kde''' in K-Menu-->Applications-->System-->Startup Disk Creator (Kubuntu). If it is not there, then you can install it using the [[UbuntuSoftwareCenter|Ubuntu Software Center]]. * Insert and mount the USB drive. Inserting the USB drive should auto-mount it. * Start the Startup Disk Creator * In the top pane of the Startup Disk Creator, pick the .iso file that you downloaded. * If the .iso file isn't listed, click "Other" to locate and select the .iso file that you downloaded. * In the bottom pane of the Startup Disk Creator, pick the target device, the USB flash drive. If more than one choice, please check carefully, until you are sure that you will be writing to the correct device. * After checking that you are pointing to the correct target device, the USB flash drive, you can start the action. * You must enter a password because this is a risky operation. Use the password of the current user ID (the same as for login and running tasks with {{{'sudo'}}}. Password is not required when installing from a 'live' system (booted from a DVD disk or another USB flash drive). The Startup Disk Creator '''clones''' the iso file, which means that you need neither erase nor format the target drive. It will be completely overwritten anyway by the cloning process. The Startup Disk Creator looks like this in Ubuntu 18.04 LTS: '''[[attachment:/fromUbuntu/sdc-to-ssd-or-pendrive.pdf|Screenshots: Startup Disk Creator - to SSD or pendrive]]''' '''Notes''' * '''''NEVER''''' try to use one of your hard disk drives or SSDs or partitions in this process unless you really know what you are doing, as data will get erased. * There are '''bugs''' that affect the Ubuntu Startup Disk Creator, when you run it '''in old Ubuntu versions''' in BIOS mode and try to create USB boot drives with other versions. In the Ubuntu Startup Disk Creator version 0.3.2 in Ubuntu 16.04 LTS, these bugs are no longer a problem, so you can install any version of the Ubuntu flavours from 16.04 LTS and newer versions. === UNetbootin === * [[https://unetbootin.github.io/|Download UNetbootin]] * UNetbootin works in and with most Linux distros. * It is an extracting tool (not a cloning tool). * It can make a persistence file up to 4GB in size to save data and defaults. === mkusb - dd image of iso file to USB device safely === * [[https://help.ubuntu.com/community/mkusb|Install mkusb via PPA]] * If you want to '''clone from a general image file''' to a drive, you can use mkusb. It lets you clone to any drive that is not busy, also an internal drive, and there are very '''obvious warnings''' to prevent mistakes. * mkusb can also * run in Debian and many linux distros that are similar to Ubuntu and Debian, * clone from iso files of most Linux distros to create USB boot drives, * create persistent live drives of the Ubuntu family and Debian, using all available drive space for persistence and/or data storage, * restore a USB boot drive to a standard storage device. ||<#CCFF99> There is a detailed description at '''[[/fromUbuntu]]''' including the Startup Disk Creator, UNetbootin and mkusb. || = Creating a bootable Ubuntu USB flash drive from Mac OSX = See [[How to install Ubuntu on MacBook using USB Stick|How to install Ubuntu on MacBook using USB flash drive]] and [[http://ubuntuforums.org/showthread.php?t=2174630|this Ubuntu Forum thread by Quackers]] = UEFI = There is a good wiki page about [[https://help.ubuntu.com/community/UEFI|booting with UEFI]], and a good tutorial thread, [[http://ubuntuforums.org/showthread.php?t=2147295|UEFI Installing - Tips]]. == Test if running in UEFI mode == You may want to test if your Ubuntu flavour is running in [U]EFI mode. An installed system and a live system too is using the directory '''/sys/firmware/efi''', so you can run the following command line, {{{ test -d /sys/firmware/efi && echo efi || echo bios }}} The following command line is more robust and also easier to understand, so you may prefer it (if you copy & paste and are not bothered by typing a long command line), {{{ if test -d /sys/firmware/efi; then echo efi; else echo bios; fi }}} === Boot and install === === Stable portable systems - good for USB sticks === === Creating an EFI-only image === === Ubuntu single boot in UEFI mode === ||<#CCFF99> There are more details at the sub-page '''[[/uefi]]''' || = Alternative methods = == 'Do it yourself' == When the boot structure is modified in Ubuntu or the booting software, there can be problems until the extracting tools are modified to manage the modification. It is worthwhile to find a method that is as simple as possible and to learn how to use it in order to manage the extraction also when the boot structure is modified. * For an UEFI only boot flash drive you need no installer * Make the drive boot both in UEFI mode and BIOS mode See this link: [[https://help.ubuntu.com/community/Installation/iso2usb#Do_it_yourself|Installation/iso2usb#Do_it_yourself]] === Portable installed system booting from UEFI and BIOS === === Multiboot pendrives === === Booting ISO files on internal drive === === Booting USB drives with grub2 and iso files 'grub-n-iso' === ||<#CCFF99> There are more details at the sub-page '''[[/alt]]''' || = Booting the Computer from USB = Remove all unneeded USB items, but keep the network cable attached. == Boot menu == Instead of editing BIOS settings, you can choose a boot device from the boot menu. Press the function key to enter the boot menu when your computer is booting. Typically, the boot screen displays which key you need to press. It maybe one of F12, F10, F9. == Edit the BIOS settings == Insert the bootable USB flash drive that you just created in your target computer and restart it. Most newer computers can boot from a USB flash drive. If your computer does not automatically do so, you might need to edit the BIOS settings. Restart your computer, and watch for a message telling you which key, '''hotkey''' to press to enter the BIOS setup. * It will usually be one of F1, F2, F9, F10, DEL, Enter or ESC. * The hotkey should be described in the user manual provided by the manufacturer of the computer (a printed or electronic document). * You can also search your hardware on [[http://boot-keys.org|boot-keys.org]]. '''Press this hotkey continuously or tap repeatedly''' (different between computers) while your computer is booting to edit your BIOS settings. (On HP Mini Netbooks, the correct key is usually F9.) == Select 'hard disk/USB-HDD0' == '''Note: with some motherboards you have to select 'hard disk/USB-HDD0' to choose the USB flash disk'''. It may work like this because the system sees the USB drive 'a mass storage device' as a hard disk drive, and it should be at the top of the boot order list. So you need to '''edit the Boot Order'''. Depending on your computer, and how your USB key was formatted, you should see an entry for "removable drive" or "USB media". Move this to the top of the list to make the computer attempt to boot from the USB device before booting from the hard disk. === Chainloading === === PLoP Boot Manager === For old computers that cannot boot from USB === Flow chart for trouble-shooting === See this link: [[https://askubuntu.com/questions/1190764/why-doesnt-a-bootable-usb-boot/|Why Doesn't a Bootable USB Boot]] ||<#CCFF99> There are more details at the sub-page '''[[/bootUSB]]''' || = Known Issues = * There are problems with the versions of the Startup Disk Creator alias usb-creator in versions of Ubuntu older than 16.04 LTS. There are similar problems with old versions of Unetbootin. Until these problems are solved other tools work, for example '''mkusb''' and '''!Win32DiskImager''' described in the following links, [[https://help.ubuntu.com/community/mkusb]] and [[https://wiki.ubuntu.com/Win32DiskImager/iso2usb]] * The version 0.3.2 (and newer versions) of the Startup Disk Creator alias usb-creator in Ubuntu 16.04 LTS (and newer versions) '''clones''' the iso file and creates a read-only file system. This method is very robust, but '''if you want to re-use the USB stick as a storage drive, you must restore it'''. Two methods are described in the next paragraph. = Postrequisites - restore the USB stick = 'Postrequisites' - after installation: how to restore the USB stick to a standard storage drive.
