USB Xubuntu 8.04 install from Linux

USB Xubuntu persistent Install from Linux; This tutorial covers the process of installing Xubuntu 8.04 to a USB flash drive from within a running (Ubuntu) Linux environment. Xubuntu uses the xfce desktop environment as opposed to Gnome or KDE. Xfce runs smoother and quicker on older and slower PCs. In addition, this installation tutorial utilizes the Casper persistence feature to enable changes to be saved and restored on subsequent boots.

If you have access to a working Linux installation and your system does not have a CD drive, this tutorial is for you.

Note: Tested to create a USB Xubuntu 8.04.1. Changes might be needed for other versions.

USB Boot essentials:

  • Running Linux environment (we used a local Ubuntu installation)
  • Established internet connection
  • 1GB or larger USB flash drive

How to make a Bootable USB Xubuntu from Linux

  1. Insert a 1GB or larger USB flash drive (2GB+ recommended)
  2. Open a terminal and type sudo su
  3. As one line, type wget
  4. Type mount -o loop -tiso9660 xubuntu*.iso /cdrom
  5. Type fdisk -l to list available drives/partitions (note which device is your flash drive I.E. /dev/sdb). Throughout this tutorial, replace all instances of x with your flash drive letter. For example, if your flash drive is sdb, replace x with b.
  6. Type umount /dev/sdx1
  7. Type fdisk /dev/sdx
    • type p to show the existing partition and d to delete it
    • type p again to show any remaining partitions (if partitions exist, repeat the previous step)
    • type n to make a new partition
    • type p for primary partition
      • type 1 to make this the first partition
      • hit enter to use the default 1st cylinder
      • type +750M to set the partition size
      • type a to make this partition active
      • type 1 to select partition 1
      • type t to change the partition filesystem
      • type 6 to select the fat16 file system
    • type n to make another new partition
    • type p for primary partition
      • type 2 to make this the second partition
      • hit enter to use the default cylinder
      • hit enter again to use the default last cylinder
      • type w to write the new partition table
  8. Type umount /dev/sdx1 to unmount the partition
  9. Type mkfs.vfat -F 16 -n xubuntu8 /dev/sdx1 to format the first partition
  10. Type umount /dev/sdx2 to ensure the partition is unmounted
  11. Type mkfs.ext2 -b 4096 -L casper-rw /dev/sdx2 to format the second partition
  12. Remove and re-insert your flash drive (if prompted that a new medium has been detected, select to open in a new window and click ok)
  13. Back at the terminal, type sudo apt-get install syslinux mtools
  14. Type syslinux -sf /dev/sdx1
  15. Type cd /cdrom
  16. Type cp -rfv casper dists install pics pool preseed .disk isolinux/* md5sum.txt README.diskdefines install/mt86plus /media/xubuntu8
  17. Type cd /media/xubuntu8
  18. Type wget
  19. Type cd casper
  20. Type rm initrd.gz
  21. Type wget
  22. Reboot your computer and set your system BIOS or Boot Menu to boot from the USB stick. Save your changes and proceed to boot from the USB device.

You should now be booting from your USB Xubuntu flash memory stick with persistence. By default it should also save your changes persistently to the USB Xubuntu persistent block file or overlay image. Restoring those changes on subsequent boots.

Notes: If your having trouble getting USB Xubuntu to boot, your memory stick may have a corrupted MBR. To repair the MBR of your USB device, at the terminal type sudo apt-get install lilo then type lilo -M /dev/sdx (replacing x with the letter of your flash device)
