Ubuntu 12.04 fstab corrupted

I'm running Ubuntu 12.04 in my pc and for some accident my /etc/fstab file became corrupted, i have already checked and no backup was made. The pc has installed Windows as well and I don't really know how to build the file based on the information of the blkid command and the mtab file. Although i'm familiar with the syntax of the fstab file, I don't know what information has to be inlcuded based on the situation of having a windows partition besides Linux so I has hoping somebody could help me with the construction of the file.

Here's the blkid info.

/dev/loop0: TYPE="squashfs" 
/dev/sda1: LABEL="Recovery" UUID="BA04384104380345" TYPE="ntfs" 
/dev/sda2: LABEL="Vista" UUID="608085478085249E" TYPE="ntfs"     
/dev/sda5: UUID="ffc7dedc-ce6c-45a9-b233-7ce214682178" TYPE="ext4" 
/dev/sda6: UUID="1347e64b-d51e-4410-ae43-cfdac8959583" TYPE="swap" 
/dev/sr0: LABEL="Ubuntu 12.04.4 LTS i386" TYPE="iso9660"

And the mtab file.

/dev/sda5 / ext4 rw,errors=remount-ro 0 0
proc /proc proc rw,noexec,nosuid,nodev 0 0
sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0
none /sys/fs/fuse/connections fusectl rw 0 0
none /sys/kernel/debug debugfs rw 0 0
none /sys/kernel/security securityfs rw 0 0
udev /dev devtmpfs rw,mode=0755 0 0
devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=0620 0 0
binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,noexec,nosuid,nodev 0 0

Currently, i'm booting from the live CD so I guess one of the devices is the CD media.

Based on you mtab and blkid output, your system has two major linux partitions /dev/sda5 which is mounted as / and /dev/sda6 which is mounted as swap. Rest other partitions are virtual file systems and they will be mounted automatically by the init during the time of reboot.

Add below lines to your /etc/fstab file and reboot the system, it should be safe.

# <file system> <mount point>   <type>  <options>       <dump>  <pass>
/dev/sda5   /   ext4    errors=remount-ro 0       1
/dev/sda6   none    swap    sw              0       0
/dev/sr0        /media/cdrom0   udf,iso9660 user,noauto     0       0

It is not necessary to consider windows partition at this stage if you are not mounting any of the windows partitions.

I am running Ubuntu 12.04 and looking at my fstab, I think this should work for you (I updated with your UUIDs):

proc            /proc           proc    nodev,noexec,nosuid 0       0
# main
UUID=ffc7dedc-ce6c-45a9-b233-7ce214682178 /               ext4    errors=remount-ro 0       0
# swap
UUID=1347e64b-d51e-4410-ae43-cfdac8959583 none            swap    sw              0       0
