What is wrong with your system? If you followed the procedure on news
https://web.obarun.org/index.php?id=116 or on obnews package ( $ sh /var/cache/obarun/news/66_upgrade_v0.2.0.4_to_v0.2.1.2.news) you shouldn't have any problems.
root:
# nano /etc/66/init.conf
change verbosity=3
ctrl-X y y
# mount -a
any errors?
#
# 66-disable -t boot All
# 66-disable -t boot-user All

# 66-enable -t boot boot
# 66-enable -t root -F tty@ tty1 tty@ tty2 .... all other services you need

reboot and if there is a problem either from emergency shell or tty12
cat /run/66/log/0/current >/home/saleem/current.log
mount installation /mnt chroot /mnt from other system/live and copy /mnt/home/saleem/current.log here
