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:
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).
linux /hdinst-vmlinuz ramdisk_size=14972 root=/dev/rd/0 rw --
Can anyone help me in this regard? Thanks!
