The Gist:

I have been trying to erase my disk and install Ubuntu 14.04 LTS on my laptop as my sole operating system. I can boot "Try Ubuntu" or "Install Ubuntu" from a USB stick. During the graphical install, after I select "Erase disk and install Ubuntu" as my installation type, I have a choice to select between one of two RAID0 drives on which to install Ubuntu. (One is 18.2GB and the other is 439GB, so I naturally pick the larger one.) Regardless of which drive I select, one of two bad things generally happens.

In the first case, I get an error message saying "???" as soon as I proceed to the next screen. In the second case, I successfully manage get past the next screen, get 75% of the way through installing updates and packages, and then the installer crashes.

Precisely what I did before reaching this state:

  1. Downloaded Ubuntu 14.04 LTS (Trusty Tahr) 64-bit PC (AMD64) desktop image.
  2. Ran md5sum on the file and checked that it matched the hash on Ubuntu hashes. It matched correctly.
  3. Used Universal USB Installer (on Windows) to format my USB drive (FAT32) and mount the image on my drive.
  4. Re-booted with the USB drive plugged in, entered the boot menu, and selected "Try Ubuntu." Ubuntu successfully loads.
  5. Clicked icon on desktop labeled "Install Ubuntu 14.04 LTS" to open Graphical Installation.
  6. Chose all recommended options up until the screen that says "Installation type", where I selected "Erase disk and install Ubuntu."
  7. I then had a choice between two drives on which to install Ubuntu: an 18.2GB drive labeled RAID0RST and a 439.2GB drive labeled RAID0SYS. I selected the larger drive.
  8. I reach a time zone screen, then an error message saying "???" appears. I can't click anything. My screen goes black and freezes. I tried this installation approach a few different ways, each time with the same result.
  9. At this point, I wanted to start over fresh, so I opened GParted, deleted all of my partitions, and rebooted as before. When I do this, I usually manage to get past the screen with the "???" message successfully, although the installation crashes 75% of the way through installing updates at the end.
  10. Now I have two different partial Ubuntu installations on my boot menu, both of which I can open. However, I don't trust either of them because both show several obvious signs of an incomplete installation.

Hardware

Asus Zenbook Ux51Vz-XH71 Brand new, sexy. Came with Windows 8 Pro 64-bit out-of-the-box. Specs are listed here.

PNY 16GB USB 2.0 stick (P-FD16GATT03-GE). New. FAT32 formatted out-of-the-box.

EDIT: I mostly resolved my issue here. (See comments in the Hannu's answer.) My only remaining issue is that I have duplicate ubuntu entries in my boot menu.
