My Ubuntu LiveUSB won't boot after formatting it on Windows XP. HELP!

view full story

http://askubuntu.com – I formatted because the Windows XP I was using wouldn't let me view the drive in the window without formatting first, so I just said what the heck. Turns out, after using the Linux USB creator, placing the ISO on disc properly and booting, BIOS hangs; no bootloader, no startup, nothing. Windows XP's formatting screwed something up with my USB's filesystem, and I'm uncertain of what to do. Help?! My business depends on me using an OS, so prompt ideas are a must and very appreciated(no money). PS: I checked the contents of the disc, and they are all okay. (HowTos)
