How to Create UBUNTU Bootable USB/Pendrive from Windows

Minimum Requirements:

• Above 1GB USB.Flash Drive
• Ubuntu ISO
• CD Burner/Recorder
• 7-zip (or another ISO extracting tool)

Steps:

Partition and make the USB flash drive bootable:

1. Download the Ubuntu 6.10 ISO and burn it to CD
2. Restart your computer (booting from the Ubuntu Live CD)
3. Insert a 1GB or larger USB flash drive
4. Open a terminal window and type sudo su
5. Now type fdisk -l to list available drives/partitions (note which device is your flash drive Example: /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 usb /dev/sdx1 to format the first partition
   

   "Alternately you can try mkfs.vfat -F 32 -n usb /dev/sdx1 (doesn't always work)"

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
13. Back at the terminal, type sudo apt-get install syslinux mtools
    
14. Type syslinux -sf /dev/sdx1
15. Restart your computer, remove the CD and boot back into Windows

Using Windows to prepare and move the files to the USB Stick:

1. Create a folder named USB on your computer
2. Download UBconvert.zip and extract the files to the USB folder
3. Move the Ubuntu 6.10 ISO downloaded earlier to the USB folder
4. Click fixu.bat from the USB folder (follow on screen instructions)
5. Move all files from the ubuntu directory to your memory stick
6. Reboot your computer and set your system BIOS to boot from USB-HDD or USB-ZIP. Also set the "Hard Disk Boot Priority" if necessary.

You should now be booting into Ubuntu Linux from your USB drive!
