Check the iso and CD
Get Lubuntu from Download lubuntu. It is very important that you check both the downloaded file for corruption, and the CD for a bad burn.
Corrupted file downloads are less than common, but we insist you check your downloads before you report any problems with Lubuntu.
Check both at once with the "Check Disk for Errors" (only on the Desktop ISO)
or
Check for file corruption with an MD5 sum or by using BitTorrent (automatically checks for corruption)
Check that the CD Burning utility verifies the burn. More info here.
