Currently I am trying to re-size my sda1 ex4 partition using a live ubuntu dvd but I can't seem to get gparted to help my current partition 248.59GB to use the additional free unallocated 577.41GB.  Any suggestions?

See images for the description also.

Delete the swap partition, and after that also the extended partition in which it sits. After that you can resize your sda1. When done create a new swap partition in the space left over. When that is done check your /etc/fstab file and change the entry for the swap partition so it reflects the new one (usually you have to change partition ID, which you can view via gparted).

The reason you can't resize now is because you have the swap partition between your current partition and the unallocated space. The space must always border right to the partition you want to resize.

Rindi,

There is a key the surrounds the extended and swap partition what do you suggest to get around that?

Currently the screen shots are done via live cd.

I don't understand what you are asking. Just delete the swap partition, then the extended one.

Just FIRST delete the swap partition, and AFTER that the extended one. The extended partition is a container for further partitions, and your swap partition is inside that, you can't delete an extended partition until all it's contained partitions are removed.

The reason for having extended partitions is because with the old MBR disk scheme you had a limit of 4 primary partitions per disk. So if you made one of the 4 possible primary partitions an extended one, you were then able to have many logical partitions inside that. With the new GPT disk scheme that limit has gone and you can have many primary partitions. So for those you don't have extended partitions anymore.

Yes, if the Ubuntu LiveCD is using the swap partition you must first turn swap off.

If you don't intend to put more than 4 partitions on the Disk, you won't need the extended partition. In gparted just select new when you right click in the unallocated space you have left, and there you can select what type of format, or whether that new partition shall be a swap partition.

You should have a swap partition, but it doesn't have to be in an extended one. You can just use a primary partition for it. It also doesn't have to be large, I usually make mine 512MB (it isn't like in Windows where you need 1.5x the size of your RAM for the pagefile).
