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@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen

So booting the xen.efi binary directly from UEFI ?

[Fedora-xen] Fedora 18 and EFI
I have successfully installed Fedora 18 Beta as Dom0 on one computer, and am now trying to do the same on another. I am using all of the standard Fedora 18 packages, including xen-4.2.0-6.fc18.x86_64. On the second computer, I ended up with an EFI grub2 install. I used yum to install xen, and noted that the package installation did not update /etc/grub2-efi.cfg. I ran grub2-mkconfig by hand, and this added Xen entries to /etc/grub2-efi.cfg. However, booting failed: grub2 complained that it did not know the multiboot keyword. Does anyone have experience getting EFI grub2 to boot Xen/Fedora 18? Is my trouble expected? -- Mike :wq -- xen mailing list xen@lists.fedoraproject.org https://admin.fedoraproject.org/mailman/listinfo/xen
