I just installed F7T2 x86_64 and selected to install GRUB to the boot sector of the partition onto which I was installing the system (/dev/sda7). I selected this because I have a multi-boot system and wanted F7T2 to have control of its own GRUB. Just like my experience with F7T1, after all the packages were installed, I got a backtrace from anaconda (see attached). It appears it failed when trying to write the bootloader.
