I have downloaded the iso file and burned it to a USB stick. I restarted my Mac and booted from the USB drive. When I did, I got the message, “error : file ‘/boot’ not found.” I tried pressing “e” and then entering “nomodeset” but it still will not fully install. I have gotten to the point where it tells me to remove the USB drive and press enter. I do that and it appears to be working for a while, but then it just quits. During this time, I get the messages,
INFO: task Xorg:1751 blocked for more than 120 minutes.
Not tainted 4.10.0-19-generic #21-Ubuntu
echo 0> /proc/sys/kernel/hung_task_timeout_secs disables this message.
Will someone please help me fix this so that I can install Ubuntu?
