For me -- on a laptop -- F29 -> F30 left me with no entries in
grub.cfg. It seems to be a BLS problem.
grub.cfg did contain:
insmod blscfg
blscfg
/boot/loader/entries has 5 .conf files and a rescue.conf
grub gave no menus.
Oddly enough installing xen package resulted in xen appearing in
grub.cfg, but no non-xen kernels:
insmod blscfg
blscfg
if [ -s $prefix/grubenv ]; then
load_env
fi
### END /etc/grub.d/10_linux ###
### BEGIN /etc/grub.d/20_linux_xen ###
menuentry 'Fedora, with Xen hypervisor' --class fedora --class gnu-
linux --class gnu --class os --class xen $menuentry_id_option 'xen
gnulinux-simple-e4ae4541-8eca-4483-91cc-af6b83a9fdc5' {
insmod part_msdos
insmod ext2
set root='hd0,msdos3'
...
(sidenote: non-linux non-windows entries disappeared completely, under
all conditions.)
This is using a BIOS, not EFI. (EFI on this laptop is kaput.)

Try disable BLS in /etc/default/grub and re-running grub-mkconfig
