I was in fact (unknowingly) using a Debian 5 ISO over a 'Debian GNU/Linux 5
(64-bit)' template which was causing it not to get me into the shell on root
partition file system. Now, with a debian-6.0.7-amd64-netinst.iso, I was able
to get to shell on the root file system in rescue mode.Then I ran
`update-initramfs -u -v` followed by `update-grub`. They both appear to run
fine (without showing any errors) though I didn't understand much about why
they needed to be run.. Is there anything in the output that I should be
looking for?I tried running the preseed file again after this but the installer
stopped at the same place as before ("No root file system found").perhaps, I
should try recreating a new initramfs? (`update-initramfs -d` followed by
`update-initramfs -c`)?
