"How can I install 64-bit Ubuntu on my 32-bit UEFI Bay Trail atom tablet?"
To those of you who marked this question as off-topic, because it is related to a no longer supported version of Ubuntu… This was posted in May, before Ubuntu 14.10 had reached it's End of Life. reference below:
Ubuntu announced its 14.10 (Utopic Unicorn) release almost 9 months
ago, on October 23, 2014. As a non-LTS release, 14.10 has a 9-month
month support cycle and, as such, the support period is now nearing
its end and Ubuntu 14.10 will reach end of life on Thursday, July 23rd

Note: As of right now, Ubuntu 15.04 will BOOT on a bay trail tablet, but it will not install correctly.
My guide is based mostly on this one, but with minor adjustments, and easier to follow instructions. This guide is tested and working on the Winbook Tw100 Windows 8 tablet (by Microcenter).
You may require:
Problem 1: Booting a 64-bit OS with a 32-bit UEFI BIOS on a 64-bit CPU (it's like a jigsaw puzzle)
EFI/BOOT/
folder of the bootable Ubuntu 14.10 USB drive you just createdNOTE: due to broken links, files have been moved to Google Drive for permanent storage.

You should be presented with a screen like this, choose "Try Ubuntu without installing"![enter image description here](https://i.stack.imgur.com/pKagM.png)
Problem 2: Installing, and making the installation stick!
After Ubuntu has finished booting, manually partition your tablet's internal storage
1.5. If you want to Dual-boot Ubuntu and Windows 8, you'll have to do all your partitioning using Windows disk management
you might need to change the "(hd0,gpt5)" and "/dev/mmcblk0p3" sections of code to suit your specific needs
Now enter the "boot" command. If you were successful, you should not have received any error messages, and booted into your freshly installed Ubuntu 14.10 installation. If you receive any error messages, try the last two steps again.
after that has finished, open the USB drive, and install these two .deb packages in the order that they are listed
Open a terminal, and type "sudo update-grub"
And you're done!!! If you followed these steps very carefully, and to the letter, then you have a (not-so) fully functioning 64-bit Ubuntu 14.10 (and possibly Windows 8 dual-boot) bay trail tablet.
What doesn't work (this is a list for the Tw100, your tablet may be different)
