Problems on booting

[familiavendetdo]

Hello everyone,

I am facing some troubles in order to start my Ubuntu 9.10 - Karmic Koala.
Once I start my computer, the memtest86+ is executed but it never comes to an end.

Just by using a boot CD I can finally see my Desktop...

My question to you guys is:

- How can change (remove) this call to the memtest86+ during the boot process and let the computer starts normally?

Thanks!

Memtest86 is starting everytime you boot your machine?

Have you changed any settings with the bootloader?

Post the contents of /boot/grub/grub.cfg

Thanks for your answer:

eduardo@meyer-pc:~$ /boot/grub/grub.cfg
bash: /boot/grub/grub.cfg: Permission denied

eduardo@meyer-pc:/$ sudo /boot/grub/grub.cfg
[sudo] password for eduardo: 
sudo: /boot/grub/grub.cfg: command not found

The memorytest runs everytime I start my computer.
I did no changes to the bootloader. (I dont even know how to do it in fact )

Thanks!!

grub.cfg is a file not a command

In a terminal run the following commands and paste the output here

cat /boot/grub/grub.cfg

and

cat /etc/defaults/grub

You should not change the first of these files yourself.

Well, I'm not too familiar with the new grub2 in Ubuntu, but it looks to me like you don't have an entry for your Ubuntu install, so it's skipping to the memtest.

### BEGIN /etc/grub.d/10_linux ###
### END /etc/grub.d/10_linux ###

This bit should look more like

You can try reinstalling grub2 from the live CD. Instructions are #12 in this post.

Hi there elija!

Sorry but I am completely new to Linux

No worries, we all started there

The second command should have been

cat /etc/default/grub

Sorry my bad!

Anyway, going by the grub.cfg file it appears that there are only entries for the memtest. How did you install Ubuntu?

I installed it through a DVD bought in an IT Magazine.
I couldnt start the Linux without the DVD though. I need it to boot the system.

Thanks!
