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'. Chris Murphy -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
