Can I use a command at the grub> prompt to boot from usb?












0















I installed Ubuntu on my older macbook air. It worked for awhile, and then it started acting all buggy. Now I want to turn the machine into a generic chromebook. I have created the bootable USB stick (Cloudready from Neverware), but I can't get into the bios to change the boot order so it will boot from the usb. Something is wrong and BIOS won't come up for me. I have the error "missing operating system". I can get to a grub> prompt, but I don't know if I can do anything from there?? I am way way out of my league here. Totally clueless. I have read many questions and answers looking for info and/or resources but I have not seen anything to even help me get started. Any help is greatly appreciated.
