| − | == Install Ubuntu from a USB stick ==
| + | This page gives instructions on how to run Ubuntu from a USB flash drive for installation or other purposes. This may be necessary for netbooks and other computers without CD drives and is handy for others because the thumb drive is so easy to use. The Ubuntu 9.10 CD/DVD ISO images come with the necessary Windows and Linux utilities to get the system on a thumb-drive. |
| − | This pages describes how to install Ubuntu by copying the contents of the installation CD to an USB drive (such as a self-contained flash drive or a Memory Stick or SD card reader) and making the USB drive bootable. This is handy for machines like ultra-portable notebooks that do not have a CD drive but can boot from USB media. | + | For Custom, manual, older versions, and technical instructions and troubleshooting see: [[UbuntuHelp:USB Installation Media|USB Installation Media]]. There are also network installation options available. You can also see the [https://help.ubuntu.com/9.04/installation-guide/i386/boot-usb-files.html instructions for USB drives] from the official Install Guide. |
| − | The main steps are: | + | == Known Issues == |
| − | * Prepare the USB drive
| + | 9.10 netbook remix does not bring up broadcom wifi automatically, one will have to install it, then navigate the USB drive to pool and install a few packages manually with dpkg to get networking up. https://bugs.launchpad.net/ubuntu/+source/jockey/+bug/449268 |
| − | * Boot the computer from your USB drive.
| + | If you just get a black screen when booting from USB, using the setting "Discarded on shutdown, unless you save them elsewhere" in usb-creator might help. http://forum.eeeuser.com/viewtopic.php?pid=658619 |
| − | * Install Ubuntu as you would from a normal boot CD
| + | == Gather Prerequisites == |
| − | ''Note:'' It is highly recommended to use the latest version of Ubuntu to prepare your USB drive.
| + | === Installation Type === |
| − | See also the [https://help.ubuntu.com/9.04/installation-guide/i386/boot-usb-files.html instructions for USB drives] from the official Install Guide.
| + | ==== Netbook Remix ==== |
| | + | * 1GB thumbdrive with everything backed up elsewhere |
| | + | * iso image file, or cd and another computer ubuntu-netbook-remix iso, or kubuntu-netbook iso, or |
| | + | * Optional, large capacity SD card for storing ISO and or backing up data |
| | + | ==== Desktop or Server ==== |
| | + | * 2GB thumbdrive, or just do network install |
| | + | === Computer used to make USB disk === |
| | + | ==== Windows ==== |
| | + | * Virtual Clone Drive, or other iso reading software or CD burner and blank disk, (or disk) |
| | + | * what level access to a computer? |
| | + | * usb-creator.exe comes with the .iso |
| | + | ==== Linux ==== |
| | + | * usb-creator (sudo apt-get install usb-creator) |
| | + | * administrator priviledges on computer used to set up thumb drive |
| | + | == Acquire (k/x/media)Ubuntu ISO == |
| | + | netbook / 32bit / 64bit, kubuntu, etc See ... (presumably you know what kind you want). |
| | + | Disk from friend, download, order one.. etc. |
| | + | == Copy files to USB stick == |
| | + | === ISO to USB Stick USB-creator Method === |
| | + | === From Linux === |
| | + | * The utility: usb-creator can be installed normal way with apt if not allready present on your system |
| | + | * run usb-creator |
| | + | * Top Pane, You will have to click "other", locate and select the .iso image |
| | + | * Plug the- to-be-nuked- USB thumb drive into the computer, it should show up in the bottom pane. |
| | + | * You will probably have to click format, make sure you have the right device! |
| | + | * There are bugs with the formatting, It may show up as two partitions, try selecting each of them (sdb sdb1 on mine, but this changes), one should work, if not restart the computer and try again. |
| | + | If you get a DBus error with USB creator: this bug report maybe helpful: https://bugs.launchpad.net/ubuntu/+source/usb-creator/+bug/458334 |
| | + | === From Windows === |
| | + | burn the iso file or use use virtual clone drive to access the files within the image. |
| | + | usb-creator.exe is located in the CD image. Does not exist on the 9.10 i386 image. |
| | + | You won't be able to select the USB drive if it wasn't formatted in a way that windows can see it. You may have to format it using explorer, then it will show up in the creator tool |
| | + | Alternatively you can use Unetbootin to create a bootable usb drive. http://unetbootin.sourceforge.net/ |
| | + | == Boot the Computer From USB == |
| | + | Most newer computers can boot from USB, You will have to go to the bios, and put either removable drives, or USB media before the hard drive. This is computer dependant, and it also depends on which way the USB drive was formatted, on a Dell Mini 9, it may show up as either, so it may make sense to review settings again. |
| | + | === 9.04 and before .img for netbook === |
| | If you have downloaded a .img file, please refer to the [[UbuntuHelp:Installation/FromImgFiles|.img writing documentation]] | | If you have downloaded a .img file, please refer to the [[UbuntuHelp:Installation/FromImgFiles|.img writing documentation]] |
| − | === Check your USB drive === | + | == Prepare the USB Drive == |
| − | Booting from USB storage can be very handy, but there is no guarantee that it will work with your particular combination of computer and USB drive. Even if you are able to boot from your USB drive on one computer, this does not mean that it is going to work with the next one. You can try experimenting with different settings in your PC's BIOS to make it work.
| + | * check the usb drive for files and back them up if needed, all contents will be destroyed. |
| − | Make sure to pick a drive that is large enough to hold the contents of the installation CD (about 700MB), 1GB is recommended. Versions of SYSLINUX 3.53 and before require the use of a FAT16 file system, which most 2GB or smaller USB drive come formatted with anyway. This is the most compatible file system, and is recommended. As of version 3.00, SYSLINUX works with FAT32 as well, which is handy for users of larger drives.
| + | * 1gb minimum for netbook, may be higher for other types. |
| − | Insert the USB drive you want to use for the installer. A few seconds after plugging in the USB drive run the ''dmesg'' command or ''sudo fdisk -l'' to find the device name it was assigned. The rest of the instructions refer to ''/dev/sdX1'', remember to replace X with your device location.
| + | * The windows utility won't let you select the usb drive if the drive isn't properly formatted and mounted. |
| − | === Automatic Approaches ===
| + | Booting from a USB drive created with this utility 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 [[UbuntuHelp:LiveCD|LiveCD]] environment. |

| + | |
| − | You may encounter an error when trying to boot from the USB drive, something like "Missing operating system". Make sure that you can mount the USB drive on a normal Ubuntu install, and that you can browse it in the file browser. If you can't, it hasn't been created properly. I found that using fdisk to delete the partition on the drive first, then running liveusb, worked nicely.

| + | |
| − | Don't forget to replace /dev/sdX1 with the partition name of your USB drive found in the previous section!
| + | |
| − | You will see some "operation not permitted" errors when the script tries to copy the symlinks for /dists/stable and /dists/unstable. This is because fat16 file systems do not handle symlinks, but it will not cause any problems.

| + | |
| − | === Manual Approach ===
| + | |
| − | In short here's what you have to do:
| + | |
| − | * Make the USB flash drive bootable using SYSLINUX. | + | |
| − | * Copy the contents of the Ubuntu CD to your flash drive (make sure you include hidden files/directories).
| + | |
| − | * Rename the <code><nowiki>isolinux</nowiki></code> directory to <code><nowiki>syslinux</nowiki></code> and the file <code><nowiki>isolinux.cfg</nowiki></code> to <code><nowiki>syslinux.cfg</nowiki></code>
| + | |
| − | * ''only for old versions of syslinux:'' Copy some files from sub-directories to the root directory and edit <code><nowiki>syslinux.cfg</nowiki></code> a bit.
| + | |
| − | * Boot the computer from your USB flash drive.
| + | |
| − | * ''only for the Alternate installer CD and pre-7.04 versions:'' Create a fake CD-ROM drive and mount the flash drive to <code><nowiki>/cdrom</nowiki></code> during the Ubuntu installation process.
| + | |
| − | * ''only for the Alternate installer CD and Ubuntu 8.04:'' See [http://ubuntuforums.org/showthread.php?p=4404569 a forum post] on a file system support issue.
| + | |
| − | ==== Make your USB stick bootable with SYSLINUX ====
| + | |
| − | SYSLINUX is a boot loader that operates off an MS-DOS/Windows FAT filesystem. Most USB flash drives come with a FAT filesystem. Here's how you can add a SYSLINUX bootblock to your USB drive:
| + | |
| − | <ol><li>Make sure that "syslinux" is installed. SYSLINUX is available for both Linux and MS Windows (the executable is in the archive under \win32\syslinux.exe). For more information check the SYSLINUX homepage: http://www.syslinux.org/. On Ubuntu Linux, install it with:</li></ol>
| + | |
| − | | + | |
| − | <pre><nowiki>
| + | |
| − | sudo apt-get install syslinux mtools</nowiki></pre>
| + | |
| − | <ol><li>Attach your USB drive to your computer and mount it. This may happen automatically. If you are using Linux and it does not get mounted automatically, you can mount it by using a command such as <code><nowiki>mount -t vfat /dev/sda1 /mnt </nowiki></code>. Note the mountpoint (i.e. <code><nowiki>/mnt</nowiki></code> in the example. If you are using Windows, it should get mounted automatically. (If it doesn't your version of Windows is probably pretty old, and you'll need to install a driver for the USB drive first. Check the vendor's homepage.) Note the drive letter that Windows assigns to it (for example <code><nowiki>F:</nowiki></code>).
| + | |
| − | </li><li>Make the USB drive bootable. If you're using Linux and your USB drive is mounted as in the above example, use: <code><nowiki>syslinux -s /dev/sda1</nowiki></code>. If you are using Windows and the flash drive has the letter <code><nowiki>F:</nowiki></code> assigned to it as in the above example, use: <code><nowiki>syslinux -s -m F:</nowiki></code>
| + | |
| − | </li><li>You should see a new file called <code><nowiki>ldlinux.sys</nowiki></code> in the root directory of your flash drive. (Note that it is a hidden file, you might not see it in Windows Explorer; try <code><nowiki>dir /a F:</nowiki></code> from a command prompt). Now you can boot from your USB drive. Read on once you get a SYSLINUX message and a ""boot:"" prompt.</li></ol>

| − | ''Regarding the IDE disk: When in the USB cradle, the disk is sda,
| + | |
| − | whereas when I mount it in the Libretto as the primary IDE disk,
| + | |
| − | it is of course hda.
| + | |
| − | (I shot myself in the foot a couple of times because of this ...)''
| + | |
| − | ''The automatic mounting is a bit distracting at times. My recommendation would be
| + | |
| − | to <code><nowiki>pumount</nowiki></code> any device you intend to do any low-level operations on,
| + | |

| + | |
| − | ''Make sure to include the -m option with the Windows version of syslinux, to
| + | |
| − | ensure that it copies a fresh ISOLINUX master boot record (MBR.) Otherwise
| + | |
| − | the preexisting MBR may be used, which therefore may not point to
| + | |
| − | your syslinux.cfg file.''
| + | |
| − | ==== Copy the Ubuntu CD to your USB stick ====
| + | |
| − | Copy the ''contents'' of the Ubuntu installation CD to your USB drive (i.e. all files and directories that are on the installation CD). Please do ''not'' copy an ISO image of the installation CD. Note that you don't have to burn the iso to copy it's contents, from linux it can be mounted like so:
| + | |
| − | <pre><nowiki>
| + | |
| − | mount -o loop /path/to/ubuntu.iso /path/to/mount/point</nowiki></pre>
| + | |
| − | Make sure you also copy hidden files and directories (eg. ones with names beginning with a "."). In Gnome, press ctrl-H to see hidden files. In MS Windows you can use the following command, assuming that D: is your CD-ROM drive and F: is the USB drive:
| + | |
| − | <pre><nowiki>
| + | |
| − | xcopy /e /h /k d:\*.* f:</nowiki></pre>
| + | |
| − | ==== Move files to the root directory ====
| + | |
| − | '' This step is not needed if you prepared the flash drive with syslinux 3.35 or newer (Ubuntu 7.10).''
| + | |
| − | Copy (or move) the files stated from the following directories to the root directory of your USB drive:
| + | |
| − | * isolinux (all files) | + | |
| − | * casper (vmlinuz and initrd.gz)
| + | |
| − | * install (all files)
| + | |
| − | - ''Downloaded Jaunty Desktop i386 iso and followed the manual procedure here, moving the files from the above folders.

| − | ==== Adjust SYSLINUX.CFG ====
| + | |
| − | For recent versions of syslinux, you just need to rename the <code><nowiki>isolinux</nowiki></code> directory to <code><nowiki>syslinux</nowiki></code> and rename the file <code><nowiki>isolinux.cfg</nowiki></code> inside this directory to <code><nowiki>syslinux.cfg</nowiki></code> .
| + | |
| − | ''For older versions:'' Copy (or rename) the file <code><nowiki>isolinux.cfg</nowiki></code> to <code><nowiki>syslinux.cfg</nowiki></code>. Then edit the file and remove the <code><nowiki>/casper/</nowiki></code> or <code><nowiki>/install/</nowiki></code> reference in all paths. For example you would change the line containing <code><nowiki>DEFAULT /casper/vmlinuz</nowiki></code> to <code><nowiki>DEFAULT vmlinuz</nowiki></code>. Save the file, and make sure it is called <code><nowiki>syslinux.cfg</nowiki></code>. It does not matter whether the line breaks are in DOS or Linux format.

| − | === After Installing ===
| + | |
| − | After finishing the installation, edit <code><nowiki>/etc/fstab</nowiki></code> and make sure that /media/cdrom0 points to the CD drive and not to the USB drive. If you don't, you might get this error when trying to mount a USB drive: "Cannot mount volume. Invalid mount option when attempting to mount the volume."
| + | |
| − | This is because the installer believes it is installing from a CD drive ([https://launchpad.net/bugs/150872 bug 150872]).
| + | |
| − | Open /etc/fstab for editing, e.g.
| + | |
| − | <code><nowiki>sudo gedit /etc/fstab</nowiki></code>
| + | |
| − | Find a line like this (usually at the end):
| + | |
| − | <code><nowiki>/dev/sdb1 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0</nowiki></code>
| + | |
| − | and comment it out by placing a # at the beginning:
| + | |
| − | <code><nowiki>#/dev/sdb1 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0</nowiki></code>
| + | |
| − | You can also rename the real cdrom mount point to <code><nowiki>/media/cdrom0</nowiki></code> if you like.
| + | |
| − | Save the file, and you're done.

| − | ==== On Partitioning the Flash drive ====
| + | |
| − | - ''I partitioned the disk for installation with room for several boot images.
| + | |
| − | I created <code><nowiki>hda1</nowiki></code> for <code><nowiki>/boot</nowiki></code> (in retrospect, maybe not necessary),

| − | <code><nowiki>hda2</nowiki></code> for swap (again in retrospect, could go in an extended partition;
| + | |
| − | if I do it again I'll add the good old Woody installer <code><nowiki>rescue288</nowiki></code> disk image
| + | |
| − | -- still viable and valuable as a rescue disk!),
| + | |
| − | <code><nowiki>hda3</nowiki></code> for the Dapper 6.06 server install CD filesystem
| + | |
| − | (this is a low-memory system which can't boot the regular live CD, I have been told),
| + | |
| − | and <code><nowiki>hda4</nowiki></code> as an extended partition for the remaining BIOS hibernation and
| + | |
| − | actual root filesystem partitions.''
| + | |
| − | ''At this stage, I only marked the installer partition as bootable.
| + | |
| − | It's a FAT16 partition (partition type 06).''
| + | |
| − | ''Since there is no filesystem yet, the newly created partition needs to be formatted.
| + | |
| − | <code><nowiki>mkfs -t vfat /dev/sdXY</nowiki></code> ... and be real careful to not format the wrong disk by mistake.
| + | |
| − | (So in my case, this would be <code><nowiki>sda3</nowiki></code> here.)''
| + | |
| − | ''No need to mount any other partitions than <code><nowiki>hda3</nowiki></code>/<code><nowiki>sda3</nowiki></code>)
| + | |
| − | although Ubuntu will in fact automatically try to mount all the ones which
| + | |
| − | have a filesystem on them.
| + | |
| − | Actually, I momentarily unplugged and then replugged the USB cable at this point
| + | |
| − | to make sure the partition table was synced OK, and then the new partition
| + | |
| − | was automatically mounted on <code><nowiki>/media/usbdisk</nowiki></code>
| + | |
| − | (and <code><nowiki>usbdisk-1</nowiki></code>, <code><nowiki>usbdisk-2</nowiki></code> etc for additional partitions or devices
| + | |
| − | ... <code><nowiki>mount</nowiki></code> with no arguments will tell you what's where, if you're unsure).''
| + | |
| − | ''Unable to boot the USB drive? Two suggestions: 1) Run <code><nowiki>install-mbr</nowiki></code> (from the <code><nowiki>mbr</nowiki></code> package) on your drive (<code><nowiki>/dev/sde</nowiki></code> for example) and 2) Ensure the partition (<code><nowiki>/dev/sde1</nowiki></code> for example) is bootable. In my experience, some machines require the partition to be flagged bootable; some don't!''

9.10 netbook remix does not bring up broadcom wifi automatically, one will have to install it, then navigate the USB drive to pool and install a few packages manually with dpkg to get networking up. https://bugs.launchpad.net/ubuntu/+source/jockey/+bug/449268
If you just get a black screen when booting from USB, using the setting "Discarded on shutdown, unless you save them elsewhere" in usb-creator might help. http://forum.eeeuser.com/viewtopic.php?pid=658619
netbook / 32bit / 64bit, kubuntu, etc See ... (presumably you know what kind you want).
Disk from friend, download, order one.. etc.
burn the iso file or use use virtual clone drive to access the files within the image.
usb-creator.exe is located in the CD image. Does not exist on the 9.10 i386 image.
You won't be able to select the USB drive if it wasn't formatted in a way that windows can see it. You may have to format it using explorer, then it will show up in the creator tool
Alternatively you can use Unetbootin to create a bootable usb drive. http://unetbootin.sourceforge.net/
Most newer computers can boot from USB, You will have to go to the bios, and put either removable drives, or USB media before the hard drive. This is computer dependant, and it also depends on which way the USB drive was formatted, on a Dell Mini 9, it may show up as either, so it may make sense to review settings again.
Booting from a USB drive created with this utility 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.
Make sure the software-sources are activated if you are on a live cd
(software sources or `sudo gedit /etc/apt/sources.list`). You may need to install the python-gnome2 package as well.
It should do everything needed you just need to have a live cd in you CD-Rom or show the usb-creator the ISO image of it and the rest of the process is automatic! (for more info how to use this tool directly by just popping in a liveCD to a Drive in a running Ubuntu desktop see also "Live USB creator" below, note that it also works directly with downloaded .iso images)
If the progress bar proceeds very slowly (1% every 10 seconds or so) you may want to make sure your usb stick is mounted without the "sync" option. This seems to work around single-byte writes bug in Jaunty's usb-creator.

This method is recommended if you are creating Linux installation to coexist with your existing Windows installation.
The mainstream method for 9.10 is using ISO cd images and usb-creator. The process can be outlined in four steps:
