install from a Workstation F29 beta image on a flash drive How reproducible: only installed one time, didn't repeatġ. Version-Release number of selected component (if applicable): I can boot by invoking the boot menu by hitting F12 during the DELL logo phase, which shows three choices under LEGACY BOOT (Internal HDD, CD/DVD, Onboard NIC) two choices in UEFI BOOT: Fedora (which leads to the expected LUKS prompt and a subsequent successful boot), and UEFI: Hard Drive and OTHER OPTIONS have the usual BIOS setup/BIOS flash update/diags/Intel ME BIOS extensions/Change Boot Mode Settings On boot, the DELL logo flashes and drops an 'Invalid partition table!' message. I used a standard Workstation image on a flash drive, and chose default installation with 'reclaim space' option, which overwrote the preexisting working/booting W10 partition scheme I believe this is a secure UEFI boot. The disk setup uses the GPT partiton table, with /boot/efi on a 182MB sda1 EFI System partition, /boot on a 1GB sda2 Linux partition and 476GB luks PV/VG/LV with the usual root/home/swap. I just installed F29 beta on a Dell Latitude e6540 laptop.
