I tried running Boot-Repair as referenced by the following question, but after restarting, I still see the same "Reboot and select proper boot device" error.
Does anyone know another viable solution? I would prefer not to wipe the system again if possible because I thought Boot-Repair had fixed the problem and spent a lot of time setting up things. FYI, my machine is a new Acer Aspire. Also, from the live install USB, I executed "check disk for errors", which reported that there was one error, but didn't say what the error was. Additionally, at least one co-worker with an identical system has the same problem.
Update: I tried to boot off of a coworker's UEFI live USB, and this didn't work. I also noticed in the BIOS Setup Utility that the hard drive is listed as "[UEFI: ST1000DM003-1...]". Is this the issue? If so, how do I fix this?
