How to install quantal using the hd-media images?

Asked by Shriramana Sharma

Over the past years, I have always installed new releases of *buntu directly from my HDD using the hd-media vmlinuz and initrd images available from http://archive.ubuntu.com/ubuntu/dists/<version>/main/installer-<arch>/current/images/hd-media/ and booting via GRUB using the entries:

[code]
        linux /hdinst-vmlinuz ramdisk_size=14972 root=/dev/rd/0 rw --
        initrd /hdinst-initrd
[/code]

However, now that with Quantal the ISO is no longer a valid CD image, I am getting an error of "cannot load CD image" when I point the installer to the appropriate partition having the ISO in its root (which is detected BTW).

Can anyone help me in this regard? Thanks!

You can mount the ISO using Grub2. You don't need any extra functionality

Hi -- are you saying that I don't need to use the hd-media files? If so could you please indicate what kind of GRUB entry I should produce for this? For example I am currently running PartedMagic from an ISO using the following GRUB entry:

menuentry "PartedMagic" {
        set isofile='pmagic.iso'
        loopback loop (hd0,msdos5)/$isofile
        linux (loop)/pmagic/bzImage root=/dev/sda5 iso_filename=$isofile \
                edd=off load_ramdisk=1 prompt_ramdisk=0 rw vga=normal loglevel=9 \
                max_loop=256 vmalloc=256MiB
        initrd (loop)/pmagic/initrd.img
}

but I am not sure how to modify this for *buntu Quantal.

menuentry "Lucid ISO" {
set isofile="/boot/iso/ubuntu-10.04-desktop-i386.iso"
loopback loop (hd0,1)$isofile
linux (loop)/casper/vmlinuz boot=casper iso-scan/filename=$isofile noprompt noeject
initrd (loop)/casper/initrd.lz
}

In /etc/grub.d/40_custom file

Then put the ISO (in this case ubuntu-10.04-desktop-i386.iso) in /boot

Then run:

sudo update-grub

You do realize that gparted is in a default Ubuntu ISO so you don't need a specific PartedMagic ISO. The Ubuntu ISO can do everything PartedMagic does and more.
