I have a Vizio Notebook (CN15-A5). It came pre-installed with Windows 8 x64 and is taking advantage of UEFI out of the box. The BIOS (APTOS AMI) is in Secure Boot mode with the OS selected as "Windows 8".

I removed the stock HDD that came with the machine and put my own SSD into it. I created a Windows 8 Pro x64 installation disc on a 4GB USB flash drive formated as FAT32 since its apparently required for UEFI.

When I boot from the USB Win8 installation disc, I get suck when I reach the "Custom: Install Windows only" section. Normally you would see a list of available discs and their partitions, however my entire list is blank.

If I head back to the BIOS and disable Secure Boot and set the OS to "Other OS" and attempt again, I am able to see the list of available discs in the system and can install a copy of Windows 8. Unfortunately, doing it in this method results in an installation with a traditional 350 MB partition + OS partition instead of 4 partitions which is normal for a UEFI setup.

Has anyone run into this problem? I've tried loading defaults in the BIOS and attempting to install via every combination with no luck. Any help would be appreciated.
