SYSLinux Error on boot, ubuntu 13.04

Question

Want to try out Ubuntu 13.04 on my HP Pavilion dv7 1132nr but I keep getting this error.

SYSLINUX 4.06 EDD 2012-10-23 Copyright (C) 1994-2012 H: Peter Anvin et al

First of all, a few things:

1. I tried many USB installers such as Universal USB Installer, LILI, and UNetbootin, all gave me the same result

2. The drive was formatted before installation (FAT32).

3. The iso isn't corrupted, the MD5 all checked out.

4. I have another Linux Distro on this machine, would that cause this to happen?

5. The USB Drive is a Sandisk 16GB.

Hope one of you guys can fiqure this out.
