I was having Ubuntu Karmic installed on my laptop with Vista as the alternate boot. Yesterday, I downloaded the alternate CD for Version 10.04 for performing an upgrade. I mounted the iso image, which was in my home folder, to /media/cdrom0 and ran the upgrade command from console. The upgrade went fine till the computer was restarted. After restart, when I chose the newly installed Ubuntu from grub menu, blank screen with blinking cursor was displayed and it refused to boot. After a few unsuccessful attempts, I decided to reinstall Karmic again. So, when I pop in the live CD and boot the computer I get a I/O error message.
I am sure that there is no problem with either the live CD or the CD drive as the live CD works fine with other computers and the CD drive works fine in Vista.
Now, are both problems interrelated ?
What is the way forward?
