OK, so I basically formatted my USB drive and then tried to copy windows 8 installation files into the (formatted) USB. However something majorly screwed my PC up and the copying process was interrupted. I tried copying them again and then skipping the files I had already copied, but when I booted from the USB drive and tried to install windows, an error popped up, stating that a file was corrupt. So basically what I'm asking is: do I need to format my USB drive again or just copy the installation files over?
Thanks in advance..
