I need to install Ubuntu 32 bit alongside windows 8 64 bit. Can anyone tell me how to get windows/UEFI to run the 32 bit disk? I have disabled secure boot and gotten a 64 bit disk to run, but I need 32. If you are wondering why, I'm trying to fix something on my phone and the tools require 32 bit linux. I also need to either use the live DVD or actually install it. A USB or virtual machine won't work.

First, why do you think you need a 32-bit Ubuntu? Today, there's seldom any real need for this type of setup, and it does complicate a dual-boot configuration with Windows 8 in EFI mode, so I strongly recommend against it unless it really is needed.
If you really do need a 32-bit Linux, try this:
Once Ubuntu is installed, you'll need to find a way to dual-boot. Broadly speaking, there are three options:
refind.conf
file: Uncomment thescanfor
line and ensure thathdbios
is among the options. When you reboot, you should see an option for Windows and a gray diamond-shaped icon that should boot to the GRUB that your 32-bit Ubuntu installer installed. Unfortunately, the EFI features that rEFInd uses to boot a BIOS-mode boot loader aren't available on all computers, so this option might not work for you; but if it does, it can be a convenient way to proceed.Unfortunately, there are a few EFIs that are so inflexible that a BIOS/EFI dual-boot is impossible. If you've got one of them, your only hope is to use a 64-bit EFI boot loader for Linux.
Given all the caveats and the pretzel-twisting that's required to get this to work, I think you can see why I recommended sticking with a 64-bit version of Linux.
