Maybe this page can help you:https://wiki.ubuntu.com/LucidLynx/ReleaseNotes#I/O%20error%20after%20CD%20is%20ejected%20at%20end%20of%20install

The exact error after installation was like this
'902.095913] end_request:I/O error dev sr0 sector507776:
also when enter was pressed system displayed 'system will reboot now' and after reboot system diplayed 'no software to boot on any devices press any key to continue to retry"

sr0 is your optical drive. Is there a disk in the tray?

it is the usual dvd writer/player from where we install linux.
I also did some more experiment on it.I inserted the installation cd and
booted the system. It asked me for 'try ubuntu' and 'install full'. I gave
the first option. It booted well and worked well.I checked what files are
installed and whether it is properly installed. Found that some of the
directories are bearing a cross mark on them (like /usr,/boot /init.d etc.
can I do anything for them? pls advice

Hello madhava rao.

Giving its email is a good way to get lot of spam.
You can be contacted by other people other way.
They have to click on you name, and send you a message.
After you can provide -privately- your personal e-mail.

"Found that some of the directories are bearing a cross mark on them": these folders have restricted write right acces. Only administrator can modify them, which is perfectly normal.

I have difficulties to understand the situation. Can you type in a terminal:
     sudo parted -l
and post result.

Boot to liveCD and run:

sudo fdisk -l

These are your partitions

You can then run:

sudo fsck -a /dev/sda1

assuming /dev/sda1 is a partition in your system. Don't check NTFS partitions, only Linux partitions. This may fix your issue a little

I run fsck on my system the result is as follows pls tell me what to do
next.

To run a command as administrator (user "root"), use "sudo <command>".
See "man sudo_root" for details.

ubuntu@ubuntu:~$ sudo fsck-a /dev/sda1
sudo: fsck-a: command not found
ubuntu@ubuntu:~$ sudo fsck
fsck from util-linux-ng 2.17.2

I'm afraid you attached a file in your answer. Unfortunately, Launchpad doesn't manage attached files. You have to to a copy/paste in body of message.

Sounds like the lens is dirty or you have a bad CD. Did you MD5 test the ISO you downloaded? Have you checked the CD for defects?

I'm surprised because "sudo fsck -a /dev/sda1" call dosfsck, which means /dev/sda1 is Windows partition, which can't host Linux.
Can you type
    sudo parted -l
where "-l" is lowercase L, and post result.

For MD5:
Please verify the md5sum https://help.ubuntu.com/community/HowToMD5SUM of your cd
and compare the result with: http://releases.ubuntu.com/10.04/MD5SUMS

now I have installed ubuntu side by side to windows. (for which I am using
the old 4 gb HD).the 40 gb HD which I installed is as it is I have kept it
seperate.The HD in which I have installed windows xp (now) works well with
windows. Earlier I had installed windows xp in my 40 gb HD on which I
installed ubuntu 10.04 LTS during which it used entire disk and whole
windows erased. now the results I have posted is related to my 4 gb HD.Also
I have to insert the ubuntu installation cd in the cd drive (that it is
showing I/O error). pls tell me what to do next I will post the result
tomarrow. I am at office now. tks

Sorry, but I'm moving from UK to France Saturday, and will have no Internet connection for a month.

Can you boot with Ubuntu CD with option "Try without install", open a terminal and type
     sudo parted -l
where "-l" is lowercase L, and post result.
It will help others to understand easier your situation.
