This issue has been resolved, but if I can be forgiven to hijack the
thread for a related question.
What is this new uuid in menu.lst?
I notice that the entries no longer have a root (0,0) type line, which
in the old days, was used by grub to identify the /boot partition where
the kernel and initrd files were to be found. Has that been replaced
with the uuid a42730ca-039c-485d-a153-c367d8ef4f51 ?
And to the OP, do you have a separate /boot? That would explain why
your grub uuid and your kernel option root= are different.
