grub2-install /dev/sda
grub2-mkconfig -o /boot/grub2/grub.cfg
Got me a working grub2 system - however, my poor man's install option was lost.
This I corrected as below, adding it's entry in the file below
[steve@aspireone753 ~]$ sudo cat /etc/grub.d/40_custom
#!/bin/sh
exec tail -n +3 $0
# This file provides an easy way to add custom menu entries. Simply type the
# menu entries you want to add after this comment. Be careful not to change
# the 'exec tail' line above.
menuentry Fedora-17-x86_64-Live-Desktop {
set root=(hd0,msdos8)
linux /isolinux/vmlinuz0 root=UUID=B381-1423 rootfstype=auto rw liveimg quiet rhgb
initrd /isolinux/initrd0.img
}
and then re-running
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
There were some syntax changes from how it was in grub.conf ->
title Fedora-17-x86_64-Live-Desktop.is
root (hd0,7)
kernel /isolinux/vmlinuz0 root=UUID=B381-1423 rootfstype=auto rw liveimg quiet rhgb
initrd /isolinux/initrd0.img
Note especially the change in partition numbering.
