I eventually figured out how to install Fedora 18 using the MBR-style grub2. My Fedora 18 install media was a thumbdrive; what I discovered was that if I did *not* instruct my motherboard firmware's UEFI menu to boot from this USB device, then it seemed to pick it up as an old-style MBR boot instead. From that point on, Anaconda seemed to assume the computer had a BIOS, not UEFI. It appears the Fedora 18 install image supports both BIOS/MBR and UEFI, and the motherboard's firmware picks up the MBR if not explicitly asked to boot the device as UEFI. After picking through Anaconda and finding no option (i.e., a way to install using an MBR boot instead of a UEIF boot), I suspect I could achieve the same effect by manually creating an msdos partition table on the target hard drive instead of a GPT partition table. -- Mike :wq -- xen mailing list xen@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/xen
