Ubuntu gives me an error on boot saying it can't find my Swap partition.

I ran free -m and this was the result. It says I don't have any swap memory. I can't post any images but these were the results.

MEM: total(3692) used(2357) free(1334) shared (248) buffers(84) cached(908)

-/+ buffers/cache: used(1364) free(2357)

Swap: used(0) free(0) shared(0)

I tried to see if a swap partition exists on my hard drive. It does. I have allotted 60 GB to Ubuntu.

1st sub-partition device: /dev/sda5

partition type: Linux

contents: Ext4 (version 1.0) — Mounted at Filesystem Root

2nd sub partition device: /dev/sda6

partition type: Linux Swap

contents: unknown

Can anyone help?


Please check out my answer here. There are steps to check which swap partitions are in use and instructions on making the OS use them.
