Well, it won't boot off the 'flashbar', as you call it, because you haven't yet put Puppy on there!
From the sound of things, you're in Windows at the moment. Windows is telling you the 'disc in drive:E' needs formatting because Windows doesn't recognise Linux file-systems, and thinks that the flash-drive is unformatted.
You're rather getting ahead of yourself, here. Do I take it that you followed my instructions, and formatted the flash drive ready for Puppy? If so, what that's done is to prepare the flash drive ready to 'install' Puppy to it.....but you can't boot from it yet, because we haven't put the Puppy files on there yet, or installed the bootloader.
I haven't yet told you how to do this...
As with everything to do with computers, it's a series of small steps, which have to be performed in a certain order.....and every step needs to be completed. I'm quite prepared to help you do this, but please don't be so impatient. To my way of thinking, something like this should only need to be done once.....but it needs to be done correctly the first time around.
Now; please answer me one simple question. Are you prepared to follow advice? Because if you're not, then we may as well call it a day right here & now; it's just a waste of everybody's time, when I could be helping someone who is prepared to listen.
(Don't think I'm being hard on you; I'm not. But even on forums such as this, there is a certain set of 'courtesies' that we all try to follow.....because it makes things easier all round. For everybody; those who need help.....and those who try to give it. There are a lot of good people on here, who enjoy helping other people out with problems.....but if nobody will take notice of what's being suggested, then there's not much point in folks even bothering.)
