possible duplicate but earlier questions did not solve my issue. I installed Ubuntu 13.04 in my ACER desktop. Initially it was not able to start Ubuntu on normal start up as priority was not set in BIOS. So, I set priority in BIOS but still I am getting above error during boot up. What could possibly happen? Disk error/installation problem?
It sounds like the disk is in failure stages according to the message.
Start your PC and go into the BIOS and see if there is a hard disk diagnostic test and run it. Also you may see the hard drive manufacturer website, and see if they have a testing utility.
It also may have to do with the BIOS. Check with Acer, and see if they have a BIOS update.
