Do you have a block device driver built into the kernel? And what type of
shell are you dropped into when then happens? Is it a single-user mode shell
or grub (or something else entirely)? Also, while you're booted into the
livecd/dvd/usb and you chroot, try lspci -k and check to see what
modules/drivers that lists as installed and see if you have them enabled in
your config.
