I tried with this:
cat > boot/grub/grub.cfg <<EOF
insmod lvm
insmod ext2
insmod part_msdos
insmod part_gpt
if search --set root --file /boot/grub2/grub.cfg ; then
  configfile /boot/grub2/grub.cfg
elif search --set root --file /boot/grub/grub.cfg ; then
  configfile /boot/grub/grub.cfg
fi
EOF

But it's not working and it prints this line indefinitely in loop:
error: no such device: /boot/grub2/grub.cfg.

I also tried with only these lines instead of conditions:
search -s root -f /boot/grub/grub.cfg
configfile /boot/grub/grub.cfg

But all I get is the line "Welcome to GRUB!" followed by a white screen 
on xl console.
I don't know what else to try :(

Thanks for any reply.
