1.
What happens if you remove the GPT boot flag from sda2?

2.
What happens if you add the GPT legacy_boot flag to sda2?

3.
While I wouldn't recommend supporting such a solution, but I'm curious what happens if you use gdisk to create a hybrid MBR, and add only partition 3 (lvm), set it as bootable instead of the PMBR. GPT fdisk (gdisk) can do this. It's now on the F17 LiveCD. Menu 'r' option 'h'.
