The "set root=(hd1,4)" and "search --no-floppy --fs-uuid --set
17a9cefd-3754-4048-9aa9-93dc7967a107" lines at the top of your
grub.cfg are incorrect.

They should be "set root=(hd1,2)" and "search --no-floppy --fs-uuid
--set d53965e1-bcb1-4158-8531-193af32d52e7" (like within the menuentry
entries).
