[ubuntu] Can't install on Lenovo U310

view story

http://ubuntuforums.org – So, I recently got a Lenovo U310 and decided to dual boot on it. I copy the 12.04 ISO to my flash drive, and proceed to installing Ubuntu. After a few attempts I give up on dual booting, and just decided to go for a complete new install. After around 5 more attempts, I have had no luck, and currently my computer just stops at a PXE-MOF screen and then restarts. I currently have no idea whats wrong. I was trying to install '/' and '/boot' and the swap on the 32gb SSD, and then have '/home' on the 500gb HD. I tried typing in the commmands, Code: sudo dmraid -E -r /dev/sda sudo dmrai (Hardware)
