error unknown filesystem

#set prefix and root to linux partition
grub rescue> set prefix=(hd0,gpt5)/boot/grub
grub rescue>set root=hd0,gpt5
grub rescue> insmod /boot/grub/i386-pc/linux.mod
grub rescue > linux /vmlinuz root= /dev/sda5 ro
grub rescue > initrd /initrd.img
grub rescue > boot


Setelah masuk ubuntu, instal grub
dengan perintah berikut di terminal

#install grub
sudo update-grub
sudo grub-install --force /dev/sda
sudo reboot

Alhamdulillah sudah berhasil dengan cara saya diatas. silahkan di save ngeh,
barangkali perlu dan sedang tidak ada live
cd

jika tidak berhadil coba pakai

#Alternative solve
#set prefix and root to linux partition

grub rescue> set prefix=(hd0,gpt5)/boot/grub
grub rescue>set root=hd0,gpt5
grub rescue >insmod normalgrub rescue >normal
