What is your current fstab? also: to recreate it you need the output of sudo blkid (shows the uuid of each filesystem) and cat /etc/mtab (shows mount options). edit: see ubuntuforums.org/… for an example on how to recreate it. –  Rinzwind Apr 4 at 10:50

An example on how to recreate fstab can be found on ubuntuforums.org

You need the result of:

$ sudo blkid
/dev/sda1: LABEL="EFI" UUID="3F3C-1AF6" TYPE="vfat"
/dev/sda2: UUID="83062D46C78FDD33" LABEL="Macintosh HD" TYPE="hfsplus"
/dev/sda3: UUID="9A1C07811C075821" TYPE="ntfs"
/dev/sda4: UUID="58e05acc-a255-48c7-ac8a-acbf5a7764c9" TYPE="ext3"
/dev/sda5: TYPE="swap" UUID="dc91869f-897e-47d1-a472-98551ae03fa5"

and of:

$ cat /etc/mtab
/dev/sda4 / ext3 rw,relatime,errors=remount-ro 0 0
tmpfs /lib/init/rw tmpfs rw,nosuid,mode=0755 0 0
proc /proc proc rw,noexec,nosuid,nodev 0 0
sysfs /sys sysfs rw,noexec,nosuid,nodev 0 0
varrun /var/run tmpfs rw,nosuid,mode=0755 0 0
varlock /var/lock tmpfs rw,noexec,nosuid,nodev,mode=1777 0 0
udev /dev tmpfs rw,mode=0755 0 0
tmpfs /dev/shm tmpfs rw,nosuid,nodev 0 0
devpts /dev/pts devpts rw,noexec,nosuid,gid=5,mode=620 0 0
fusectl /sys/fs/fuse/connections fusectl rw 0 0
lrm /lib/modules/2.6.28-17-generic/volatile tmpfs rw,mode=755 0 0
securityfs /sys/kernel/security securityfs rw 0 0
binfmt_misc /proc/sys/fs/binfmt_misc binfmt_misc rw,noexec,nosuid,nodev 0 0
gvfs-fuse-daemon /home/dan/.gvfs fuse.gvfs-fuse-daemon rw,nosuid,nodev,user=dan 0 0

With these results you can re-create a fstab file. Based on the example it would be:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
proc            /proc           proc    defaults        0       0
# /dev/sda4
UUID=58e05acc-a255-48c7-ac8a-acbf5a7764c9 / ext3 relatime,errors=remount-ro 0 1
# /dev/sda5
UUID=dc91869f-897e-47d1-a472-98551ae03fa5 none swap defaults 0 0

But your /etc/fstab will be different. You will have different UUID's, different discs and can have different mount options.
