I wants to place Ubuntu 13.04 Server edition ISO Image to USB pendrive and then automatic installation by help of this usbdrive.
I perform following steps:
(1) Format the pendrive, Assuming my pendrive recognize as /dev/sdb in my system, I wrote this command
sudo mkfs.ext3 /dev/sdb
(2) Then i install grub2 on pendrive ( I am using grub2 due to fact that it can read ISO image file directly without extract its content to usbdrive)
sudo mount /dev/sdb /mnt/USB
sudo grub-install --force --no-floppy --boot-directory=/mnt/USB/boot /dev/sdb
(3) Now i wants to perform automatic installation , i created a pre configuration file and named it preseed.cfg, I have two options first either to place this file into initrd.lz and setup will load this file automatically, I tried this but dont get any success so i tried second way and place preseed.cfg file to root of usbdrive.
sudo cp preseed.cfg /mnt/USB
(4) Now i copy ubuntu iso image to usbdrive.
cp ubuntu.iso /mnt/USB
(5) I changed grub2 so that this can read ubuntu iso image , i did following changes
cd /mnt/USB/grub
sudo nano grub.cfg
(6) Format of grub.cfg
set timeout=10
set default=0
menuentry "Run Ubuntu Live ISO" {
loopback loop /ubuntu.iso
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=/ubuntu.iso splash --
initrd (loop)/casper/initrd.lz
}
(7) I already changed txt.cfg under isolinux folder and remaster ISO image, Format of txt.cfg
default autoinstall
label autoinstall
menu label ^Install Ubuntu
kernel /casper/vmlinuz.efi
append file=/cdrom/preseed/preseed.cfg boot=casper initrd=/casper/initrd.lz quiet splash --
preseed/file=/hd-media/preseed.cfg
(8) Format of preseed.cfg
