Just made my USB bootable via pendrivelinux but now when I reboot I can't choose the USB - my only options to show up are Windows 7 and Ubuntu from a previous wubi version I used (won't boot, btw) What do I do?

That's for booting from a CD or DVD, but Josef wants to boot from a USB drive, so he should select Removable Devices rather than CD-ROM Drive as in that article. Furthermore, when relying on external sources, it is preferable to include the essential parts of the answer here, and provide the link for reference. So you may want to edit your post to expand it and account for the difference between booting to a USB flash drive and booting to an optical drive. – Eliah Kagan Jun 13 '12 at 21:38
