boot-repair (grub rescue>)

Um probleminha que tive hoje foi o grub rescue no PC de casa.

error: no such partition Entering rescue mode... grub rescue> _

O que aconteceu?

Fui remover a partição linux, já que eu iria trocar de distro, sendo que estava em dual-boot com o windows 7, e quando reiniciei entrei na tela do grub rescue.

Como resolver?

Se você também está com esse problema, não se desespere. Há várias soluções para resolver esse problema e aqui irei dizer a que funcionou comigo. (Eu estava com um pendrive bootável de uma distro que usa o gerenciador de pacotes apt, o que facilitou bastante.)

Passos:

fazer um pendrive bootável com uma distro linux que tenha o gerenciador de pacotes apt (caso já tenha, ir para o 2º passo)

abrir o terminal

(no terminal)

# adiciona o repositório ppa yannubuntu/boot-repair sudo add-apt-repository -y ppa:yannubuntu/boot-repair # atualiza a lista de pacotes disponíveis sudo apt-get update # instala o boot-repair e executa-o sudo apt-get install -y boot-repair && boot-repair

reiniciar (no terminal)

reboot

Fixing mounting errors with /etc/fstab

Recently came across this faulty SSD Optimization article online that basically asked to add some argumetns for each of the storage devices in the /etc/fstab.

The additional arguments being the noatime,nodiratime,defaults, and mode.

The article erroneously directed to put all the aruguments altogether without any delimeters.

This completely wrecked the boot process. After the HDD encryption was unlocked, it simply would not boot from the storage devices, since the mount flags were faulty.

The fix is to drop into the boot repair command line through advanced boot options and then edit the /etc/fstab file.

It wasn’t that simple though, since the /etc/fstab file was essentially corrupted because of the wrong boot flags argument(s), and so the fstab was loaded as read-only only.

To be able to write changes to the fstab after adding ’,’s between all the arguments, the storages have to be unmounted. To unmount storages -

mount -n -o remount /

But if the fstab is corrupted (which in our case it was) you have to specify the storages -

mount -n -o remount /dev/sda /

(replacing /dev/sda between sda1to however many partitions exist on the system for eg. sda4).

Save changes to fstab and reboot.

How can I repair grub? (How to get Ubuntu back after installing Windows?)

I installed Windows 7, which ate Ubuntu’s boot file. When starting up the computer, it now goes straight to Windows, without giving me the option of booting Ubuntu.

Boot Repair in Ubuntu - Tutorial

Earlier this week I restarted my computer after upgrading Ubuntu from 11.10 to the 12.04 Version, when I did the hard drive would not boot back up. The first thing I did was tear up a little and panic because of the amount of data on the hard drive that I have not learned to make back-ups of yet. After the initial panic I remembered reading something about a boot repair utility that could help fix the problem, provided the hard drive just hadn't decided to die.

Below I will put the links to the programs used and for further help if needed from the Ubuntu website.

So I first had to check to see if the hard drive was still readable which I did by using the utility UNetbootin to install Ubuntu onto a thumb drive. Once the thumb drive was ready I plugged it into the computer and booted into Ubuntu off of it. I checked to see if I could get to the data on the hard drive and thankfully I could.

My next step was to get Boot-Repair onto the computer and run it. To do this you must open up a terminal and  type sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update. When it is done you can then install the  program by typing sudo apt-get install -y boot-repair. After the installation is complete you just need to type boot-repair into the terminal and the program will open.

Once the program opens click the Recommended Repair button. When it is finished shut off the computer, remove the thumb drive, and try to boot off the hard drive.

For me it worked and I rejoiced. However if the repair is unsuccessful it tells you to copy and paste the url the program will give you in the Ubuntu forums and ask for further assistance.

For next kubuntu upgrade

/!\ Do a backup of /home before upgrading!

If after upgrade there is no more Grub, use boot-repair and set Grub options as no graphic mode.

If after restoring Grub there is no graphic interface, remove nvidia package

apt-get purge nvidia-current-updates

Restart and reinstall nvidia package with jockey.
