Need help installing on UEFI system

http://forums.fedoraforum.org – I'm trying to install F17 on a new HP box with UEFI. My disk layout is /boot/efi 256M EFI System Partition 2M BIOS Boot / 32G EXT4 /sl6 32G EXT4 /home 183G EXT4 On my first install the installer didn't demand a BIOS boot partition, after install it booted to a blank GRUB command line. On the next install it demanded a BIOS Boot partition. After that install the system sees no boot devices at all. I've tried putting the boot loader into both the MBR and into the root partition (the only two options offered by the installer), it makes no difference (HowTos)
