Answer: How-to: Installing Ubuntu Linux on a usb pendrive

This tutorial will show how-to install Ubuntu on a usb stick. Even though this tutorial uses Ubuntu as its base distribution, you could virtually use any type of Linux liveCD distribution.

Being able to run Linux out of a usb bar is a great way to enjoy the live CD experience (being able to use Linux on any computer you might get by) and the big advantage of being easier to carry around than a CD.

1. Requirements
In order to reproduce this tutorial, you will need a few items such as:

a ubuntu liveCD
a usb bar of at least 1G
a running Linux operating system
Now that you have all this, it is time to prepare you USB bar do host the Ubuntu liveCD files.

2. Setting up the USB disk
2.1. Finding the device
In the first place, you need to plug your usb drive and check under which device it is associated. To find out the device, run:

$ sudo fdisk -l

On my system, the device appears as being /dev/sdb, I will therefore use /dev/sdb as a reference for this tutorial, please replace it accordingly to your system (might be sda, sdc …).
Once you found your device, you are going to create the partitions.

Using the wrong device name might destroy your system partition, please double check

2.2. Making the partitions
Make sure every of your already mounted partition are unmounted:

$sudo umount /dev/sdb1

and then launch fdisk, a tool to edit partition under linux:

sudo fdisk /dev/sdb

We are going delete all the partition and then create 2 new partition: one fat partition of 750M which will host the files from the live CD iso, and the rest on another partition.

At fdisk prompt type d x where x is the partition number (you can simply type d if you only have one partition), then:

n to create a new partition
p to make it primary
1 so it is the first primary partition
Accept the default or type 1 to start from the first cylinder
+750M to make it 750 Meg big
a to toggle the partition active for boot
1 to choose the 1 partition
t to change the partition type
6 to set it to FAT16
Now we have out first partition set up, let’s create the second one:

n to create yet again a new partition
p to make it primary
2 to be the second partition
Accept the default by typing Enter
Accept the default to make your partition as big as possible
Finally, type w to write the change to your usb pendrive
Partitions are now created, let’s format them.

2.3. Formatting the partitions
The first partition is going to be formated as a FAT filesystem of size 16 and we are going to attribute it the label “liveusb”.

$ sudo mkfs.vfat -F 16 -n liveusb /dev/sdb1

The second partition is going to be of type ext2 with a blocksize of 4096 bytes and the label casper-rw. Mind that it has to be labeled as casper-rw otherwise the tutorial won’t work!.

$ sudo mkfs.ext2 -b 4096 -L casper-rw /dev/sdb2

At this stage, our usb pendrive is ready to host the liveCD image. Now, let’s copy the files to the usb bar.

Hi,

its a very basic question from a newbie like me.
while performing “step 2.3 formatting”, I get following problm –

my usb is mounted as /dev/sdc1 and now I have added two partition on it as said. but while formatting which device should I use. I am confused because in the article it says sdb1 and sdb2 which might be the partition in the USB for author. for me its /dev/sdc1p1 and /dev/sdc1p2. when I try to format by this name my host can not identify this and gives error like no such device.

please help soon

thanks

You might want to use: fdisk -l

You might want to use:
$ sudo fdisk -l

This will output the different partition you have, then pick up the right one.

linux off USB
Submitted by riyasmp on Sun, 2007-05-06 21:34.
hi guys

i am trying to get around a problem for the last one month. since i am not a computer expert most of the answers what i get is not sufficient. as somebody put it giving a link and asking to read manual is not helping me at all. i will summurise the issue and will ask you the perticular things i want to know.

i have got a sony vio laptop which doesnt support USB boot.i have got an external USb HDD on which i want to put any of the linux distro preferably ubuntu. i tried with fedora and ubuntu but did not work. some of the forums opined that you can get around this problem with installing GRUB on MBR. when i restart grub menu never comes up.

can any one help me with this issue please.i would be happy if u tell me with making a bootable CD to tackle it so that i can boot from my USB HDD.

thanks

Persistent Partition
Submitted by tux on Tue, 2007-03-27 10:21.
Hello all,
Fantastic site, wish I had found it long ago!
I have followed the tutorial and it works well, one small problem that I wonder if anyone can shed some light upon.
When I boot up and select the persistent option, for the first couple of boots it works very well, on subsequent boots I get an error saying my session only lasted for 10 seconds, then I cannot log into my partition.
If I also remember correctly I think it also says something about an Xserver (though I could be wrong).
I have tried a couple of USB sticks now and they all have the same error.
If anyone could help I would be very grateful
Thank you.

custom settings and ~/.xsession-errors
Submitted by chantra on Tue, 2007-03-27 12:20.
The reason this usually happens might be due to some preferences files in your home dir.
Did you by any chance copy some user settings (~/.* files) from another install to your usb stick?
You might also find hints in the ~/.xsession-errors file
Hope this helps.

Hello chantra
Thank you for your response I will take a look and see if i can spot anything.
Not wishing to sound dull, if I cannot log into my persistent area will I find the files by looking on the Casper RW partition?

Yep, it should be on your casper-rw.
that partition should have a /home folder, look into there.
Also, if you can’t start a X session, you might want to type Ctrl-Alt-F1 and logging from the virtual console.

Submitted by tux on Thu, 2007-03-29 21:44.
Ok I tried to install to a brand new USB stick, all went well for a few boots, then the error came up once more.
I tried to Ctrl+Alt+F1 and logging in that way.
I cannot remember what the entire error is, something about ICE. not being able to do something.
I also looked of for the /~x server file but could not find it, when logging in I saw it, something about /tmp/.xo-lock needing to be removed.
Think i am going to leave it for a while now.
Thank you very much for your help

Same Login Problem
Submitted by NukePodcaster (not verified) on Mon, 2007-04-02 21:58.
I’m wondering of you solved this problem because I’m getting the same login prompt asking me for login id and password, then session ends within 10 sec.

I can run my fantastic pen drive Ubuntu like a live CD, but not in persistent mode. My knowledge of Linux has not evolved to the point that I can troubleshoot this one on my own!

Anyone out there have a solution?

Easier way

I’ve been using Puppy Linux (www.puppyos.com) off a usb for years now. Boot off the live CD then there is a nice little ‘wizard’ that installs on the drive for you! For those not sure about booting off a liveCD, I was very wary at first, try VirtualBox (www.virtualbox.org) to run a linux distro from within your XP! You will begin to enjoy it very quickly. It is a great way to find which one you like best. Personally I found Ubuntu way to cumbersome.

You could try http://www.pendrivelinux.com

They have step by step procedures from windows XP. Though u may have to use the Live CD first. But you dont need to have it installed though.

From windows
Submitted by chantra on Sat, 2007-03-17 11:51.
I’m not much of a windows user, but I know that syslinux is available for windows.
1. You should be able to achieve this by formating the usb bar as described above, but for the ext2 partition.
2. Mount the CD/ISO with whichever utility under windows (winImage…)
3. Use syslinux.exe to make the first partition of your usb bar bootable
4. The casper-rw might be created after a first boot from the usb key in normal mode.

I believe this is roughly how you might be able to achieve the same thing from windows.
