Given the grub version, it's your Wheezy install that's controlling boot.
Why did you run "grub-install"? Since you chose not to install a
bootloader, all you needed to do was run "update-grub" in Wheezy.
Did you just run "grub-install"? Or "grub-install /dev/sda"? (I
wouldn't have thought that "grub-install" would work.
Do
grub-probe --target=fs_uuid --device /dev/sda7
and
blkid -c /dev/null /dev/sda7
return the same value and does it correspond to the UUID in the
"search" and "linux" lines of the Ubuntu entry in grub.cfg?
