I created a USB boot of Ubuntu 16.04 , pop it in and see things going okay for a while.. but then after a minute of booting I get a prompt I've never seen before..

the drive is a brand new sandisk usb 3.0 16GB

any idea?? is the bios preventing me from dual booting? I checked and secureBoot is off.

  • You may have two problems. Boot with the nomodeset option, and unplug all USB devices. Don't try and run long-term on a USB flash drive. Make sure write-protect is off.

    Ah, you created an install USB flash drive. Then you may need to use nomodeset and/or your USB flash build didn't go right, or your USB flash is defective or needs to be reformatted before use.

  • i ran the check.. after figuring out how to get into the advanced menu.. indeed it found 1 file had an error... repressing the stick now with unetbootin.github.io

  • i redid the whole process, only to get an error found again.. this USB key is brand new but maybe I should return it and get a different brand.. hearing bad things about sandisk

I wiped the thumbdrive 1-2 times , UNetbootin failed to even boot so I threw that out.. just did the plain old instructions for making a bootable drive in OS X..

If you get an error for 1 file, in the advanced menu check up.. try to install anyway.. that's what I did and everything loaded up fine. Weird.
