Ubuntu Live Persistent Flash-drive problem

[MrKitty871]

There is a new product coming out, called StormFly. it's currently on kick starter at the moment (http://www.kickstarter.com/projects/...t?ref=category)
I saw this and wanted to make one of my own, I've made a lot of bootable flash drives before, even a few persistant ones, so i kind of know a little bit about it. but only ever 4 gigs. i have a sandisk cruzer 16Gb and i really want to make a portable operating system just like stormfly.

if you look at some of the stormfly videos all they do it boot the usb from the bios and it boots up just like any other operating system, with a loggin screen and everything. i was never able to do that, as far as the login screen.

so my real question is how i would make the ubuntu os run regularly on my flashdrive while it still using the full 16Gb. not just 4Gb. if you need any more information, just ask
if anyone could give me some instruction on how to do that, that would be awesome.
thank you.

Following is step by step how to install 12.04 on a 8GB flash drive, 12.10 is similar. Increase partition size for larger drives:

Turn off and unplug the computer. (See note at bottom)
Remove the side from the case.
Unplug the power cable from the hard drive.
Plug the computer back in.
Insert the flash drive.
Insert the Live CD.
Start the computer, the CD should boot.
Select language
Select install Ubuntu.
Select Download updates while installing and Select Install this third-party software.
Continue
At "Installation type" select "Something else".
Continue
Confirm Device is correct.
Select "New Partition Table"
Click Continue on the drop down.
(Optional partition for use on Windows machine)
Click "Free space" and "Add".
Select "Primary".
Make "New partition size..." about 1000 megabytes.
Location = Beginning.
"Use as:" = "FAT32 file system".
And "Mount point" = /windows.
Select "OK"
Click "free space" and then "Add".
Select "Primary", "New partition size ..." = 4500 to 6000 megabytes, Beginning, Ext4, and Mount point = "/" then OK.
(Optional home partition)
Click "free space" and then "Add".
Select "Primary", "New partition size ..." = 1000 to 4000 megabytes, Beginning, Ext2, and Mount point = "/home" then OK.
(Optional swap space, allows hibernation)
Click "free space" and then "Add".
Select "Primary", "New partition size ..." = remaining space, (1000 to 2000 megabytes, or same size as RAM), Beginning and "Use as" = "swap area" then OK.
(Important)
Confirm "Device for boot loader installation" points to the USB drive. Default should be ok if HDD was unplugged.
Click "Install Now".
Select your location.
Continue.
Select Keyboard layout.
Continue.
Insert your name, username, password, computer name and select if you want to log in automatically or require a password.
Selecting "Encrypt my home folder" is a good option if you are worried about loosing your USB drive.
Select Continue.
Wait until install is complete.
Turn off computer and plug in the HDD.
Stick the side panel back on.

Note:
You may omit disabling the hard drive if after partitioning you choose to install grub to the root of the usb drive you are installing Ubuntu to, (ie sdb not sdb1). Be cautious, many people have overwritten the HDD MBR.
You may do an update-grub later.
