Thanks for the suggestions
I think it is something to do with the usb.
I believe Im running the latest bios -68srr ver f.40 - 03/12/13
I bought a new 8gb usb stick and downloaded a fresh copy of unibeast 4.0.2. and 10.9.4. When I tried it it did exactly the same as before.
Theres nothing to take a photo of onscreen apart from a single cursor in the top left hand corner. If I use the front right usb it turns a quarter( / ). If I use any other it just lays horizontal(-).
The message that comes up is gone too quick to read.
So just to see if it would boot from a different usb I put in an old usb formatted for netbook installation and it loaded for 20 seconds until a message came up saying it didnt recognise the chipset.
I formatted the usb carefully as per instructions on the guide here. Im formatting it on a mb air running 10.9.4. Im perhaps clutching at straws but Ive tried a kingston and sandisk usb, do branded usb's make a difference? I shall try another install and delete over my netbook usb.
