Comment 31 for bug 1277865

I'm having the same problem, EFI or Non-EFI hardware.

On non-EFI hardware I recieve

Unable to install GRUB in (hd0, 1)
executing 'grub-install (hd0, 1)' failed.
this is a fatal error

/var/log/syslog has

grub-installer: info: Installing grub on '(hd0, 1)'
grub-installer: info: grub-install does not support --no-floppy
grub-installer: info: Running chroot /target grub-install --force "(hd0, 1)"
grub-installer: Installing for i386-pc platform

**NOTE** uname -a shows this as a x86_64 machine, which is correct, but grub-installer thinks i386

grub-installer: grub-install: error: disk `hd0, 1` not found
grub-installer: error: Running 'grub-install --force "(hd0, 1)"' failed
