What Filesystem/Partition Scheme did you choose during the installation? –  aatdark Sep 15 '10 at 16:44
    
i just used the erase and use the entire disk option. –  sukrit Sep 15 '10 at 17:32
    
Have your checked your media?. If you hit SHIFT (or ESC, I don't really recall right now and can't test) while booting the installer will show you a menu with more options. There is one to check the install media there. –  Javier Rivera Sep 15 '10 at 17:34
    
pressing shift or esc did not have any effect. i even tried the partition, having 60 gb hard disk gave 52 gb to ext4 and rest to swap area, still getting the same error.. –  sukrit Sep 15 '10 at 18:27

Whilst this may theoretically answer the question, it would be preferable to include the essential parts of the answer here, and provide the link for reference. –  fossfreedom Feb 24 '12 at 15:58

I have experienced this problem because of bad installation media. Download from torrent or check the MD5 sums against the ones here.

You disk is dying..
Unfortunately, ubuntu can't install correctly on a bad disk...

From your description, it sounds like your disk is dying. To confirm this, I suggest using a low-level disk integrity checking tool, like Salvation HDD Scan and Repair

Formatting the disk will only resolve problems at the filesystem level. If the aforementioned tool detects any errors, your only recourse will be to replace the disk.

Try some diagnosis on your drive, the Ubuntu-live-cd has a pretty good disc-analysis-tool! Else try SystemRescueCd 1.6.0. These tests will give you an idea if your drive is still ok.

i ran the memtest 86 and it said that it was ok and test passed. –  sukrit Sep 16 '10 at 13:35
    
Sukrit, just run the Ubuntu10.4 live-cd. Select Try ubuntu. Then System->Preferences->Administration->Diskutility. Is your disc listed up? You can perform some tests here. –  Bernard Decock Sep 16 '10 at 16:29
