Install always crashes for 14.04 LTS of any Ubuntu type

[BCW142]

No real idea, just the start of install, Mythbuntu, Ubuntu, Lubuntu have all crashed for 14.04 LTS and 64 bit, I've been trying to install for weeks. All versions are bad. 32 bit stuff works, 12.04 LTS 32 or 64 bit works, 14.04 LTS 64 Bit doesn't. Sometimes it's just the grub that won't install (doesn't seem to be on the install DVD or it's in the wrong place), other times it's before that, but it always crashes. Hmm, haven't tried text mode install yet, guess that's next.
