I tried to install Ubuntu in my laptop ASUSX401A. I removed Windows in the partition table at the installation. All okay up to here, however when I reboot the HD after finish the installation, the HD was not recognized, in the BIOS it appears that the HD only option was the Realtek card, then was impossible to enter to Ubuntu. After that I tried again to install Ubuntu but now I have a error in the input/output when I wanted the enter the table partition. 

I appreciate any help.
