A short while back I downloaded Kali 1.0.7 to my desktop. The SHA 1 numbers matched so I know I got a good download. Next, I used Win32DiskImager to 'write' the Kali Linux iso to a 32 gigabyte Cruzer thumb drive. (My lap top dual boots Windows XP Pro and Linux 12.04 LTS with the help of Acronis OS Selector.)

So I plug the thumb drive into a USB port, and try to boot Kali. All I get is the following error message from Acronis:
"Boot partition missing"

What am I doing wrong? I have Kali Linux 1.0.6 up and running with no problems whatsoever. Why can't I boot Kali Linux 1.0.7?
