Please provide more specific information about the boot error and the packages upgraded before. If the update was installing a new kernel, you might want to switch back to your previous one. A backup should have been placed in your grub menu.

Hi fly,

thanks for your answer.

How can I read this from the system (specific information about the boot error and the packages)?

If the update was installing a new kernel, you might want to switch back to your previous one. A backup should have been placed in your grub menu.

Well, you ordered the system to download and install updates, you should have had a look them before. Never ever install updates, just because an automated system tells you that it's good/checked/tested/wont do any harm. However, there should be a log file at /var/log/dpkg.log

How do I do that?

Uhm, on 10.04 it's the ESC which envokes the menu, however you might just want to look at your grub configuration. If you installed a clean 9.10, you will have grub2, so you might want to look at [1]:

According to an email that was sent out today Monday, August 10, 2009 with the newest Grub2 update, the boot menu is hidden by default now. It's easy to get it back, just edit /etc/default/grub and comment out GRUB_HIDDEN_TIMEOUT

Code: Select all

$ sudo nano /etc/default/grub


Make your timeout line look like this...

Code: Select all

#GRUB_HIDDEN_TIMEOUT=3
GRUB_TIMEOUT=XXX        <---Make sure you put in a timeout value here.


Save the file and exit, then run...

Code: Select all

$ sudo update-grub

Hey fly,

thanks for your answer.

$ sudo nano /etc/default/grub

The System don't find the file. In the folder that file is only available:

console-setup.

What should I do?

thanks for your help!

It's not quite easy to identify problems remote via a webforum. I can just guess. Given the time difference, this might not be critical, so why don't you just reinstall the system from scratch? Yep, it's a windows like approach, but I think this can be done in a matter of hours while diagnosis (and testing and fixing..) here will take some time...
