Kebiasaan bersih-bersih laptop kadang-kadang tidak selalu berakhir bagus. Seperti baru-baru ini. Maksud hati ingin membersihkan semua kernel source dan kernel image versi lama yang sudah menumpuk (karena setiap kali Ubuntu desktop update, kernel image yang lama tidak dihapus), malah ketika booting kernel-image saya yang baru hilang juga. Menu di daftar booting grub<\/em> juga tidak memunculkan boot ke Ubuntu, dan untungnya laptop menggunakan dua OS.<\/p>\n

Untuk mestore kernel image yang terhapus, saya menggunakan Live CD Ubuntu (per tulisan ini, Ubuntu yang saya gunakan adalah Ubuntu Desktop 13.10). Boot ke Live CD, dan buka shell console dan jalankan langkah berikut:<\/p>\n

Karena saya menggunakan dual OS (Windows dan Linux), maka saya perlu mengetahui di mana meletakkan filesystem Linux.<\/p>\n

# fdisk -l<\/strong><\/p>\n

output:

di atas terlihat lokasi instalasi Linux berada di \/dev\/sda6<\/strong>. Pastikan koneksi internet sudah tersambung terlebih dahulu, atau setidaknya pastikan CD instalasi Ubuntu sudah siap dimount<\/em> (karena kita akan melakukan instalasi kernel-image) lalu lakukan berikut:<\/p>\n

# umount -a<\/strong>
\n# mount \/dev\/sda6 \/mnt<\/strong>
\n# mount –bind \/dev \/mnt\/dev<\/strong>
\n# mount –bind \/sys \/mnt\/sys<\/strong>
\n# mount –bind \/proc \/mnt\/proc<\/strong>
\n# chroot \/mnt<\/strong><\/p>\n

keterangan<\/em>:\u00a0Pertama unmount semua filesystem yang dijalankan dari Live CD. Lalu mount lokasi disk tempat instalasi Linux kita berada. Setelah itu mount direktori spesial seperti \/dev<\/strong>, \/sys<\/strong>, dan \/proc<\/strong>. Dan perintah chroot<\/em> akan mengubah root filesystem ke \/mnt<\/strong> dan kita bisa menjalankan aktifitas seperti laiknya kita boot dari Linux kita sendiri. Sampai di sini kita tinggal menjalankan perintah:<\/p>\n

# apt-get install -y linux-image-generic<\/strong><\/p>\n

Reboot laptop, dan harusnya grub<\/em> sudah menampilkan kembali menu opsi booting ke Ubuntu.<\/p>\n","protected":false},"excerpt":{"rendered":"
