It is not necessary to edit grub.cfg, Press "e" when the grub menu
appears and delete it temporarily there.

Deleting the "search ..." line should not prevent the box from
booting. I tested that last October; I could boot with only one of the
"set root=" and "search ..." lines.

They are duplicating each other's work. The "set root=..." line sets
root as a grub device and the "search ..." line sets root as a uuid.
