Trying to install 10.04 on desktop, computer says insert installation media
Okay, so I try to install Ubuntu 10.04 LTS on my desktop. I had 10.04 on that desktop before on a 40gb HDD so I took an 80gb HDD out of another computer in this one and tried to boot up. I put in the install Disk, all was going fine. I chose to erase disk and so on. It installed. I clicked to restart the computer and it went to a black screen, ejected the disk and it just kept that black screen for 10 minutes and in every line it say I/O error. So I turned off the power supply switch, flipped it again and powered up. the HDD shows up in the BIOS and is set to the primary Boot Device after installation. I reboot the computer and it goes in with a flashing underscore and then it says 'insert media CD and press any key.' Rebooted and the same thing happened 3 times in a row! HELP!!!
