Ubuntu - Win8 laptop - Secure Boot - GPT vs MBR...
While on one hand, I could use MBR, I'd really like to figure out how to get GPT working. Some discussions with both Windows channels and Linux channels reveals one similarity - everybody believes that the operating system has nothing to do with it, and that the issue is largely between the BIOS and the hardware itself. For what it's worth, I did successfully flash the latest BIOS without issue.
I tried several different partitioning schemes but have yet to find one that worked using GPT as my partition table. I set a 1MiB partition, unformatted, and flagged it as bios_grub, but that did nothing. I also tried to set a separate /boot partition at 500MB, but that too did nothing. Overall, GPT was an instant road block, whereas MBR worked fine. But.... why? Does anybody have any idea as to why this is or what I can do to get GPT working?
EDIT - Sometimes things are best left if on auto pilot. I left Ubuntu do the guided partitioning. Once the installation was done, booting up was a success. I installed GParted and checked out what Ubuntu did. Ubuntu had added its own EFI Partition (FAT32, 94MiB in size) at the very beginning of the drive. I ended up redoing it but this time chose manual and selected a 94MiB FAT32 partition to be selected as EFI Boot Partition and bam, that was it. All works well now, whether I use MBR or GPT tables. I am no longer insanely frustrated with ASUS, but I can't say the same for Microsoft. At any rate, we're good.

- I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
Good report on your experience with this. It will help others who have this sort of problem with new EFI/(in)Secure-boot systems.Sometimes, real fast is almost as good as real time.
