I've recently been having trouble booting my computer.

I tried to re-install some NVIDIA drivers after an update broke CUDA and led to some poor video performance. However that led to some conflicts, so I totally lost the graphics, and couldn't get beyond the command line TTY screen.

I tried a reboot, but it just hung after selecting Ubuntu 14.04. Then I tried the Boot Repair CD to no avail. Here is the log.

As of now, trying to boot from it, I get error: no such device: 90cc5126-fb61-4bb20aafe-b9ad22f26644; then it goes into a boot rescue command line. I think something went pretty terribly wrong, because glancing at the log, it looks as though there's no OS detected at all.

After that didn't work, I unplugged all of my hard drives, hooked up a brand new one, and tried to install 16.04 on it, but again I couldn't boot. This time the error just said to insert a boot device. I again tried the Boot Repair CD, but it didn't work again. Here is the second log.

I really appreciate any ideas that you'll have. I'm really not sure what it could be, but I'm a total novice with this aspect of any Linux system, so I thought it would be good to reach out to you.

As you have placed a brand new hard disk in an UEFI system, you first need to restore the UEFI partition. Try them in the following order:

  1. The original System restore DVD/CD/USB from your hardware's manufacturer
  2. The Open Source rEFInd
  3. Go back to BIOS: no more worries about Unified Extensible Firmware Interface (UEFI) problems. This one is hardware-dependent and on some systems might need a BIOS-flash.
