Man, you gotta luv the internet and all you networkers out there! I don't think I would have been able to get through the install without your suggestions. I would not have figured out you needed to go through the install twice (once from CD/ISO, and once after reboot). Might have guessed the /dev/loop2 bit, but it is alway nicer not to HAVE to guess. So THANKS you guys!
I did have one minor problem, when the install said it could not install grub on /dev/loop2 (fatal error), but I selected it again when it gave me the chance and it seemed to go through the second time without a problem.
Windows Vista 32bit + Mint 13 Maya MATE 64bit dual boot = SWEET! (Well, maybe not the windows part, but it is still useful for some things.)
We be stylin' now, fellow babies!
