You mean this CD?
ubuntu-12.04.1-alternate-amd64+mac.iso
er... yes, but mine does not have that 12.04.1 iteration, it's only 12.04. thanks for the heads-up. perhaps that's the culprit.
In this case alternate refers to the fact that the CD is a text based installer, and is different from the desktop, live CD. The +mac bit refers to the fact that EFI booting has been disabled. If you want to boot a live CD in BIOS compatibility mode, then try this CD:
ubuntu-12.04.1-desktop-amd64+mac.iso
Alternatively you could try booting with EFI, which makes USB booting possible, but has some obscure GPU issues. In this case look for this CD:
ubuntu-12.04.1-desktop-amd64.iso
okaie dokie. Here's what I'm doing. I've decided to simply erase all the partitions I created on my Mac's HD, save of course, the EFI, the Mac OSX, and the MAC OSX boot partitions that Apple decrees its users must have. Having said that, I find it strange I cannot delete the swap partition of 4GB that I had created earlier. But let's see what happens when I come to the fresh install stages again.
Next, am downloading not one but four iso images, all 12.04.1 versions. At least hopefully one of them should work using the usb-stick or the special partition method:
1. ubuntu-12.04.1-dvd-amd64.iso
2. ubuntu-12.04.1-dvd-i386.iso
3. ubuntu-12.04.1-alternative-amd64.mac.iso
4. ubuntu-12.04.1-desktop-amd64.mac.iso
am going to attempt the install starting with 4. then 3. then 2. then 1.
after that i should probably take a sledgehammer to my macbookpro and buy an intel ultra book. but sadly, that is not an option. i do need Apple LogicPro and some other Mac software. sigh!
And possibly read this blog post:

thanks for the link. this one for brave hearts. I don't qualify.
p.s. Did you check the CD integrity before installing?
