I am attempting to load Win8-Pro 32-bit from a SATA DVD when booting UEFI (as opposed to legacy). I am getting C000_0185 error very early in the access to the DVD. I know several ways to get around this issue, boot legacy, use a USB DVD or USB flash drive but I need to determine why UEFI boot to SATA DVD fails. Is this supported by Win8, or a known issue or a Bios problem? Just another data point, I get the error with or without the SATA hard drive installed, I was trying to figure out if the error was referring to the HD or the DVD.
