not booting with grub2

[gold_finger]

Okay, I don't know what the solution is but found where the problem is.  I made copies of the following files in Mint 16 (that is in control of booting) after installing LL 2.0 Final which did not boot:

/boot/grub/grub.conf
/etc/default/grub
/etc/grub.d/ (all files in this directory)

Then I re-installed LL 2.0 Beta and made copies of the exact same files in Mint 16 (which now successfully boots LL again).

I did file comparisons of the two /boot/grub/grub.conf files and found many differences.  The differences show up in the section where /etc/grub.d/30_os-prober is called and adds the entries for LL.  The two 30_os-prober file copies are identical, so what ever it is reading from the two versions of LL and entering into /boot/grub/grub.conf is different.

I've attached copies of both grub.conf files to this post.  Below is just an outline of the differences I found between the two.

Lines #200 & 201:
    Working LL 2.0 BETA -- grub.conf has this:
    linux /boot/vmlinuz-3.13.0-24-generic root=UUID=47878fc3-f171-4697-bbd8-fc706765b2bc ro quiet splash $vt_handoff
initrd /boot/initrd.img-3.13.0-24-generic

Non-working LL 2.0 Final -- grub.conf has only this:
linux
