Mengembalikan GRUB bootloader yang hilang pada Ubuntu Linux

    Tutorial ini akan menjelaskan bagaimana mengembalikan grub setelah menginstal Windows 7/Vista/Xp. Jika anda menggunakan dual boot PC dengan jendela, Ubuntu karena alasan tertentu anda instal ulang windows Anda sekarang Anda mungkin tidak melihat grub 2 adalah loading karena instalasi windows Anda mungkin sudah selesai ditulis MBR (Master boot record).

     Hal ini biasanya terjadi jika instalasi Ubuntu tidak beres, atau ketika Windows bootloader menimpa MBR dan tidak mengenali instalasi Linux. Maka kita harus mengembalikan GRUB bootloader agar dapat booting kedalam Linux

Untuk mengatasi hal tersebut ikuti ,langkah-langkah di bawah ini :


1 Pertama-tama kita harus mempersiapkan Ubuntu Live CD, jika ngga punya bisa juga menggunakan bootloader dari flash disk


2 Kemudian ubah settingan pada BIOS, CD atau flash disk pada urutan pertama (first boot option)


3 Jika PC Anda sudah diset untuk boot ke CD-ROM, Anda bisa menunggu sampai layar pilihan boot Ubuntu muncul pilih saja Try Ubuntu (without any change on your computer)


4 Setelah masuk Live CD Desktop jalankan Terminal dengan meng-klik menu Applications > Accessories > Terminal


5 Cek partisi Linux kita dengan menggunakan perintah


    $ sudo fdisk -l


6 Masuk dalam GRUB, perintahnya


    $ sudo grub

7 Selanjutnya lakukan langkah berikut :


   $ grub> find /boot/grub/stage1


misalkan didapatkan hasil (hd0,6), ini adalah informasi yang akan kita gunakan untuk mensetup pada tahap selanjutnya.


8 Kemudian melakukan setup instalasi GRUB :


    grub> root (hd0,6)
    grub> setup (hd0)


9 Jika proses installasi sudah selesai, keluar dari shell GRUB.


    grub> quit


10 Jika tidak ada pesan error maka setelah Anda melakukan Reboot, bootloader akan kembali seperti semula.

Recover a damaged desktop

           If you’ve been tweaking your system to the point of breaking, and find that the GNOME desktop no longer appears when you attempt to login,click the Options button on the login screen, and click Select Session.

            Next select Failsafe GNOME and click Change Session. Then login as usual.From here you should be able to repair your desktop or possibly even use the Users and Groups program to create a new account to use in future (nothing like a fresh start, eh?).

           If that doesn’t work, you can try deleting your GNOME desktop configuration files and starting again. This is possible because, if GNOME doesn’t find configuration files where they should be, it will automatically create some afresh. Deleting these files is very radical because it will delete all your desktop settings, plus those for GNOME applications (although your Evolution mail and account settings will remain because they’re stored in the .evolution folder). However, if you have no other choice...

Log out of the desktop and then switch to a new virtual console ( Ctrl + Alt + F2 ).
Then login and type the following:

$ rm -rf .gnome-2

Then switch back to GUI mode ( Ctrl + Alt + F7 ) and login as usual.

Kill a crashed GUI

             This is an oldie but worth mentioning in case you don’t know. To kill the GUI, for whatever reason, such as a crash, hit Ctrl + Alt + Backspace .There’s no warning dialog boxes when you do this—any open applications will be terminated, and data lost. You’ll be returned to the GNOME login screen, where you can login afresh.If you’re working on a virtual console and want to kill the GUI for any reason, typing the following will kill GNOME Display Manager (gdm), which “owns” the desktop processes:

$ sudo killall gdm

To get the GUI back following this, start gdm again:

$ sudo gdm
