Mounting Dynebolic on USB

[RazorbladeXtreme]

I'm using Linux dynebolic for a few days but the disc I have doesn't have a Adobe Flash enabled Firefox, so I've been trying to mount the OS on my USB but I can't seem to do it right. Whenever I try to mount, I get following error

Mounting /mnt/usb
mount: special device /dev/sdb1 does not exist
Mount failed

Done
There was one error.


I also tried open suse but it requires full installation and I don't have a hard disk to perform that, when I try to install it on my pen drive, it asks the location and I'm unfamiliar with Linux directory structure, so I can't get through it either.

I'd also appreciate if someone could name an OS which I can boot from one of the Digit discs and run it without installation (like dynebolic) and has a web browser with flash.
