This question already has an answer here:
When downloading the iso it downloads normally for awhile displaying that i have a few hours to wait and then randomly jumps to complete. Upon attempting to burn the iso to USB to install the pendrive program claims numerous file errors and then completes the format of my usb. when i attempt to boot from the usb during post it either comes up with nothing and forces me to reboot my laptop or comes up that i'm missing files and that the boot cannot continue. can anyone help me with this issue?
