My issue has been getting the laptop to know to boot and find the 256 Digital drive. i assum this is where i need to install the os.
eventualey managed to boot from the USB disk to which i had download the Zorin OS to.
However during the install it seems to be experiencing an issue namley it will not install.i get as far as auto install and that is it. What am i doing wrong? need help here please with step by step guid in setting up the partition if poss please as i am no good at this.

Am i installing to the right drive?

Please read this first: USB boot install - your problem could be any one of those four issues.

Next, I recommend the Something Else method as detailed here: Partitioning during installation
