Gparted tool partition

Setting Gparted :

1. Download the GParted Live zip file.
2. If you already have a FAT16 or FAT32 partition on your USB flash drive then skip to the next step (3).
   Otherwise prepare at least a 200 MB partition formatted with either a FAT16 or FAT32 file system.
   If the USB flash drive or USB hard drive does not have any partition, you can use a partitioning tool (e.g. gparted, parted, fdisk, cfdisk or sfdisk) to create a partition with a size of 200 MB or more.
   Here we assume your USB flash drive or USB hard drive is /dev/sdd (You have to comfirm your device name, since it's _NOT_ always /dev/sdd) on your GNU/Linux, so the partition table is like:

   # fdisk -l /dev/sdd
         Disk /dev/sdd: 12.8 GB, 12884901888 bytes
         15 heads, 63 sectors/track, 26630 cylinders
         Units = cylinders of 945 * 512 = 483840 bytes
         Disk identifier: 0x000c2aa7
   
            Device Boot      Start         End      Blocks   Id  System
            /dev/sdd1   *           1       26630    12582643+   b  W95 FAT32
       

   Then format the partition as FAT with a command such as "mkfs.vfat -F 32 /dev/sdd1"
   WARNING! Executing the mkfs.vfat command on the wrong partition or device could cause your GNU/Linux not to boot. Be sure to confirm the command before you run it.

   # mkfs.vfat -F 32 /dev/sdd1
         mkfs.vfat 2.11 (12 Mar 2005)
       

3. Insert your USB flash drive or USB hard drive into the USB port on your Linux machine and wait a few seconds. Next, run the command "dmesg" to query the device name of the USB flash drive or USB hard drive. Let's say, for example, that you find it is /dev/sdd1. In this example, we assume /dev/sdd1 has FAT filesystem, and it is automatically mounted in dir /media/usb/. If it's not automatically mounted, manually mount it with commands such as "mkdir -p /media/usb; mount /dev/sdd1 /media/usb/".
4. Unzip all the files and copy them into your USB flash drive or USB hard drive. You can do this with a command such as: "unzip gparted-live-0.4.5-2.zip -d /media/usb/"). Keep the directory architecture, for example, file "COPYING" should be in the USB flash drive or USB hard drive's top directory (e.g. /media/usb/COPYING).
5. To make your USB flash drive bootable, first change the working dir, e.g. "cd /media/usb/utils/linux", then run "bash makeboot.sh /dev/sdd1" (replace /dev/sdd1 with your USB flash drive device name), and follow the prompts.
   WARNING! Executing makeboot.sh with the wrong device name could cause your GNU/Linux not to boot. Be sure to confirm the command before you run it.
   
   NOTE: There is a known problem if you run makeboot.sh on Debian Etch, since the program utils/linux/syslinux does not work properly. Make sure you run it on newer GNU/Linux, such as Debian Lenny, Ubuntu 8.04, or Fedora 9
