sudo mount /dev/sda1 /mnt
sudo mount --bind /dev /mnt/dev
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
cp /etc/resolv.conf /mnt/etc/resolv.conf
sudo chroot /mnt
apt-get purge ufw
exit
sudo umount /mnt/sys
sudo umount /mnt/proc
sudo umount /mnt/dev
sudo umount /mnt
reboot

Lol.. Install webmin or other server management tool before you messing with firewall setting
I see you solved the problem. Fdisk showed you three partitions that you could mount. So you could use the
mkdir /mnt/somefolder
mount /dev/sdaX /mnt/somefolder
Replace the X with the partiton you wanted to mount.
Best regards!
Not sure about root pass, there should be plenty of stuff about that on the web.
UFW stores its rules in /etc/ufw/ufw.conf, ENABLED=yes seems to be the thing you want to change in it.
Depending on the distro you can hash the new password and replace the root one in the shadow file. That's risky but can work. Google more about the structure of the shadow file and how to edit it.
Why not add a ssh key and just reset the password after logging in to the original system?
