# Finding the problem and getting your system to boot again
After booting up with the dragonflybsd iso I could log in as root. Here is what I did. I ls -l /dev/serno/* , ls -l /dev/ad* and copied the devices that were available under /dev/serno/ and /dev/ad*. I then mounted the devices with mount_hammer /dev/ad0s1d /mnt and mount -t ufs /dev/ad0s1a /mnt/boot and used the command cat to inspect what /etc/fstab and /boot/loader.conf looked like. My old /etc/fstab looked like this:
-# Device Mountpoint FStype Options Dump Pass#
+\# Device Mountpoint FStype Options Dump Pass#
/dev/serno/00000000000000000001.s1a /boot ufs rw 1
/dev/serno/00000000000000000001.s1b none swap sw 0
/dev/serno/00000000000000000001.s1d / hammer rw 1
