What happens if you hit "Skip"???

'Buffer I/O error on device sda' suggests that there is something wrong with your hard drive.

Open the 'Disks' application and check the SMART status of your drive.

Have you checked the MD5SUM (https://help.ubuntu.com/community/HowToMD5SUM) of your downloaded iso file?

A corrupt installation disk could cause this sort of random error.
