i have recently installed ubuntu 11.10 on my system along with windows xp.

Previously i have ubuntu 9.04, i have deleted those partitions and installed 11.10.

installation is complete but i am unable to boot into ubuntu. Following is the error.

error: can't read file
error: load kernel first.

Any help is really appreciated.

It looks like this could be a boot issue, can you look at this question to get the information we need and then edit it into your question? Regards, – Ringtail Mar 23 '12 at 16:30

I had this same error, also with 11.10 and WinXP. I reinstalled ubuntu but this time did manual partitioning, just a single partition mounted at /, plus a swap partition. That seemed to do the trick.

The error messages you are getting are non-specific.

You can try two things.

First, and perhaps easiest, would be to try to run boot repair. Boot a live, desktop CD, open a terminal, and run the following commands

sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update
sudo apt-get install -y boot-repair && boot-repair


For additional information see -

Your second option is to run the boot_info_script

You download the script and run it, paste the link back here and we can help debug.

For details see How do I investigate boot and partition issues?
