How to fix your partition tables in ubuntu

User Mac-n-me asked how to fix partition tables in ubuntu.  Heres how to do it.

The first thing you need to do is install gparted with the live CD.  That takes a few steps, but the best tutorial I found is right here.

Once you finish with that, we want to check our current partition table.  Open up terminal and use the command

cat/proc/partitions

You can view the details about the disk by using this command:

 sudo fdisk -l /dev/sda

Now we need gparted to guess what it thinks the partition table used to be.

sudo gpart /dev/sda

After a while, it will output it's guess.  Take a look at it.  If it looks reasonable, then go ahead and accept it by using this command.

sudo gpart -W /dev/sda /dev/sda

For most cases, your partition table should be repaired.
