Here are the steps / instructions on how to make an installation usb stick for Ubuntu and creating the persistent file:
1. Download Universal USB Installer on Pendrivelinux.com Offcial Site.
2. After that, run the Universal USB Installer, if there’s Security Warning or a like, relax there isn’t any issue. Verification of the software is in question, are you sure you want to run this software?. Click Run.
3. View the License Agreement (which is ok for you to use it, as long as you won’t break the license), afterwards, Click I Agree.
4. At Step 1, Select a Linux Distro from the dropdown box, (I select Ubuntu 10.04 X), that’s i’m going to used.
(There’s a optional download of an iso, you may click the checkbox to download. Successful download may vary, depends on the version. For good results, in my opinion, Download an iso directly to the Website such as Official Ubuntu Download Site.)
At Step 2, If download is successful, you may proceed to the next step, otherwise, Browse your Ubuntu iso and open it up. Just like I did.
5. At Step 3, Select your USB Flash Drive Letter only (Your USB stick(s) is automatically detected, select on the dropdown carefully, with the correct drive letter).
Click the checkbox, to format the Drive as Fat32(This will ensure the installer place on a wipe clean and ready to use as a bootable usb stick.
(Note : You may click the checkbox, Show all Drives, but used this with caution or else a wrong drive may be formatted or any loss data will occured.)
Step 4, Put a persistent file size, to begin creating a persistent file, to be used by Ubuntu when any changes made. (This is optional – but for good results you may put as much as 1 GB, 2GB up to 4GB (maximum), depends on you USB Flash drive capacity). 4GB is the maximum persistent file size on a USB Stick.
To start, Click Create.
6. Universal USB Installer will prompt you a warning, that the following actions will be performed. Click Yes, to perform the actions (on your usb drive).
(Note : Extracting of ISO thru your USB and creating a persistent file may take longer, the results may vary depends on your current system.)
7. Afterwards you can view that the Ubuntu USB Installer is successfully finished, click Close.
8. To boot on USB Stick, select your Boot Priority on BIOS Setup/Settings, by pressing DEL or F2 (this may vary on your computer system). Then select 1st Boot Priority to USB Stick (whatever the name your usb stick is). Then save it and exit. Viola! You got it boot up to your Ubuntu Bootable USB Installer.
Note : This instructions / guides may or may not work on other Operating System to be Bootable USB Stick, the results vary and depends on the setup and also the current version. Please be advise im not held any responsibility, for any loss or damage on foregoing process.
(This instructions / guides tested on Ubuntu 11.04, Ubuntu 10.10, Ubuntu 10.04, Other Linux Distro, Windows 7)
