The thing you have to remember is that the "root (hdx,x)" option is
a Grub option, not a kernel option. It tells Grub where to find the
kernel and initrd files. If there are both in /dev/sda8, then you
need to use root (hd0,7) for both. If the kernel and initrd for the
new install of f7 are in /dev/sdb5, then you can use root (hd1,4).
