Any changes you make to the system—for example, saving a file to your desktop, changing the settings in an application, or installing a program—will be stored in the overlay file.

How to Make a Persistent Ubuntu USB Drive on Windows You’ll need a large enough USB drive to set up persistence. Ubuntu itself claims it needs 2 GB of storage on the USB drive, and you’ll also need extra space for the persistent storage.

So, if you have a 4 GB USB drive, you can only have 2 GB of persistent storage. To have the maximum amount of persistent storage, you’ll need a USB drive of at least 6 GB in size.

Is there a 'universal' way of how you can make a bootable USB drive out of a bootable dvd or cd? What makes a USB drive bootable? What makes a dvd and cd bootable? For example there is a program called which can make bootable USB drives, but seems like it only works with various linux distributions. (Tried it with a Win7 image and the, which didn't work so well.). Main reason I ask is that I have a Support DVD which came with an Asus EEE, and it of course doesn't have an external dvd drive. So I am curious if I can sort of move that dvd over to a USB drive so that I can use it without buying one.

Not asking just specifically about this one case though, I am curious to know a bit more about this in general.
