Install GParted Live in My Rescue USB

GParted Live on harddisk

http://gparted.sourceforge.net/livehd.php
Besides GParted Live CD and Live USB, we can put GParted Live on harddisk. This is howto:

Here we use grub boot loader as an example. You have to put the GParted live files in a FAT, ext2/3, reiserfs or any grub supported partition.

If you do not have such a partition, you can use gparted to resize your partition and create another partition to put GParted live. Here we assume you already have a FAT partition /dev/hda4 to put GParted live. This is how to do that:

1. Boot the OS in the harddrive, saying it's GNU/Linux.
   
2. Mount /dev/hda4 as /mnt, you can make it by: "mount /dev/hda4 /mnt"
   
3. Download GParted live zip file, and unzip all the files in /mnt, make sure you put all the files in /mnt, say, COPYING is in /mnt/, not in any subdir. You can make it by something like: "unzip gparted-live-*.zip -d /mnt" (Replace gparted-live-*.zip with the file name you just downloaded).
4. Change the dir name "live" under /mnt as another name, say "live-hd". You can make it by: "cd /mnt; mv live live-hd"
5. If your grub is version 1.x, edit your grub config file /boot/grub/menu.lst, and append the following:
   
   ================================================
   
   title GParted live
   
   root (hd0,3)
   
   kernel /live-hd/vmlinuz boot=live union=aufs noswap noprompt vga=788 ip=frommedia live-media-path=/live-hd bootfrom=/dev/hda4 toram=filesystem.squashfs
   
   initrd /live-hd/initrd.img
   
   boot
   ================================================
   
   In grub version 1 syntax, /dev/hda4 is (hd0,3).
6. If your grub is 2.x (grub-pc), e.g. on Debian Squeeze or Ubuntu 9.10, edit /etc/grub.d/40_custom, make it like:
   
   ================================================
   
   menuentry "GParted live" {
   
   set root=(hd0,4)
   
   linux /live-hd/vmlinuz boot=live union=aufs noswap noprompt vga=788 ip=frommedia live-media-path=/live-hd bootfrom=/dev/hda4 toram=filesystem.squashfs
   
   initrd /live-hd/initrd.img
   
   }
   ================================================
   
   //NOTE// In grub2, (hd0,4) means the first harddrive and the 4th partition. It's different from that in grub version 1. Then run "update-grub2" to update your grub2 config. (Thanks to Louie Chen for providing this).
   
   
   Besides, from GParted live version 0.4.8-7, you can use only the GParted live iso file in grub2 (Thanks to the patches files from grml). For example, put gparted-live-0.5.2-9.iso in dir /home/isos/, then make the grub2 custom file /etc/grub.d/40_custom like:
   ================================================
   
   menuentry "Gparted live" {
   
   set isofile="/home/isos/gparted-live-0.5.2-9.iso"
   
   
   loopback loop $isofile
   
   linux (loop)/live/vmlinuz boot=live union=aufs noswap noprompt vga=788 ip=frommedia toram=filesystem.squashfs findiso=$isofile
   
   initrd (loop)/live/initrd.img
   
   }
   ================================================
   
   Then run "update-grub2" to update your grub2 config.

//NOTE// Here we put an extra param "toram=filesystem.squashfs" so that the partition /dev/hda4 won't be locked.
Remember to check parameters in syslinux/syslinux.cfg from the zip file, copy them to here. It might be different from here, say vmlinuz path maybe different.
