Why is it looking for /root/dev ?

No idea what "no /sbin/init.007" means but the "/root/..." messages
mean to me that your initrd is not mounting your partition(s) and it
is therefore failing when it tries to move them at the end of its
scripts (init-bottom IIRC).

Are you using lvm or mdadm?

The "... reiinstall ..." should have had the same effect but you
should also try deleting and recreating your initrd with
"update-initramfs -d ..." and "update-initramfs -c ...".
