Dell Inspiron 5423 14z

hi,

installing 64bit 12.04 LTS didn't work, the system was not able to boot.
32bit version works, but of course not really good.
Installing system on the ssd-drive was not possible. gparted recognizes the disk, but setup doesn't.
any hints?

cheers
Johannes

hardware in the actual configuration is like this:
