Ubuntu :: Fix Path To /home Directory ?

I thought i'd set up the partitions correctly when i installed ubuntu, with a 15 gig "/" partision and a 45 gig "/home" and a 3.8gig "swap"

I was wrong i somehow misplaced the /home partition, and therefore didn't install it

I found this out about 4 days ago as i was running though video tutorial and realized i didnt have it setup correctly afterall

So... i did some research and found this site...[url] and i found something that seemed to work for various people, i deleted the 'now' windows partition and so i had this:

However i unmounted the /home folder following the instructions without realizing that i didnt have permissions to mount the /new home partition as it is not in the extended ubuntu 9.04 linux partition and i have no rights to it

So my question is, how do i fix the path to the /home folder (original) in ubuntu so that i can start over and do this correctly (ie; resize the extended partition and add the /newhoe directory/patition to ubuntu)

I realize that i can use a sudo command before lines to run su commands that are blocked in ubuntu, which is how i screwed up =

I cannot use anything in the menu as all links to programs are dead, i can run the add app, but it cannot install as the install folders are "not there"... i can see them in the terminal so i know my data is there and i can run the live disc to salvage it, but i cannot see it while ubuntu is loaded

Note; i have not restarted the computer and i don't know if this will block ubuntu from restarting either, so i need to fix via terminal, before i can do anything else, like letting the laptop rest.
