Hello All, Some months ago I installed a new motherboard (Asus Z97M-Plus UEFI) and an SSD. I installed Fedora 20 on the SSD without any problems (GUID partition table), but had a few issues getting Fedora to boot, either the MB manual or I'm a bit vague...one of the two, maybe both. In the end, using 'other OS' for the secure boot setting worked OK. Yesterday, for the first time since this install I had need to boot from a DVD, and it failed...always falling back to booting the SSD. After some discussions on an Asus site it was suggested that maybe I need to set the MB for IDE controller instead of AHCI, and that disabling 'fast boot' might help. Changing AHCI to IDE didn't help. Disabling 'fast boot' allowed the latest 'Gparted-live' DVD to boot, but still cannot boot older bootable DVDs that I have tried whilst testing this. Anyone have any thoughts on this? Cheers, -- Regards, Terry Duell
