Linuxcnc install via usb onto ssd..

Hi Guys,
I am trying to install via hybrid iso on usb stick. Live install runs fine. I have intel d525 mainboard and samsung evo 128gb ssd. I have tried and tried but actual install wont go, crashes or hangs at about 11%, checksum is fine. I give up with that. Going to try a full debian wheezy install and setup linuxcnc from there. Anyone had similar problems?

Cheers, james

Fixed - one of my memory sticks was bad, all working now...
