Grub Ubuntu Rescue. error: will not proceed with blocklists.

error: unknown filesystem
grub rescue>

[SOLVED 1]

Masukkan Live CD Ubuntu ke CD/DVD ROM laptop/PC dan booting ke Live CD
tersebut. Setelah berhasil masuk ke desktop Ubuntu, jalankan Terminal
dan jalankan beberapa perintah dibawah ini.

1. Anda harus menentukan dimana letak partisi Ubuntu:

$ sudo fdisk -l

Pada gambar diatas (via Terminal dan Gparted) menunjukkan kalau lokasi
instalasi Ubuntu saya adalah pada partisi /dev/sda7. Punya Anda mungkin
berbeda, bisa saja /dev/sda5, /dev/sda6, dan lainnya.

2. Mount partisi dimana instalasi Ubuntu berada:

$ sudo mount /dev/sdaX /mnt

/dev/sdaX adalah lokasi instalasi Ubuntu. Lokasi instalasi ini tergantung pada hasil pada langkah 1.

3. Install grub ke partisi yang sudah di-mount

$ sudo grub-install --root-directory=/mnt/ /dev/sda

4. Update GUBR
Setelah semua langkah diatas sukses dijalankan, yang harus Anda lakukan
berikutnya adalah merefresh GRUB yang baru saja diinstall.

$ sudo update-grub

Terakhir, restart komputer Anda untuk memastikan apakah GRUB sudah tampil pada saat booting.

$ sudo reboot

umount: /mnt: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))

$ sudo umount /mnt/proc

NB: /dev/sda6 merupakan pertisi tempat Linux di Install.

Done, everything works ... #grub #ubuntu #grubrescue #blocklists
