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

[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

$ sudo mount /dev/sda6 /mnt

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

Menghapus Kernel di Grub ubuntu yang tak beraturan dengan Ubuntu Tweak

saya kesulitan delete grub2 yang tak beraturan pada saat startup?

haloo teman2s... mohon dibantu dong... saya kesulitan delete grub2 yang tak beraturan pada saat startup, jika kiranya ada yang tau... mohon dishare. thanks

Menanggapi pertanyaan di ubuntu-indonesia.com saya mencoba menuliskan artikel ini, semoga bisa membantu.

Kali ini cara yang digunakan lebih mudah dengan menggunakan software Ubuntu Tweak. Dengan Ubuntu Tweak kesalahan menghapus kernel tidak akan terjadi lagi. karena kernel yang akan ditampilkan hanya kernel lama.

1. Install Ubuntu Tweak terlebih dahulu disini.

$ sudo add-apt-repository ppa:tualatrix/ppa
$ sudo apt-get update
$ sudo apt-get install ubuntu-tweak

2. Buka Ubuntu Tweak di Applications->System Tools->Ubuntu Tweak

 Setelah diinstall
-Pilih Package Cleaner
-Pilih Unlock dan masukan password
-Pilih Clean Kernels
-Pilih Select All
-Pilih Cleanup
-Masukan password lagi

Proses menghapus kernel lama dijalankan
Jika sukses muncul pesan Clean up successful!

Coba restart Ubuntu untuk memastikan kernel yang terbaru tidak terhapus.

Selesai :)
