I have been in the process of upgrading my MB1. So far I have increased the RAM to 16GB and changed the CPU to the i7-6700T, but I'm still having trouble creating a working clone of the 120GB SSD. I have gotten as far as being able to boot from the 1TB SSD into Windows 10, so that's something.
Anyway, I figured I would just do a backup of the original drive and then use the backup to restore the files to my 1TB SSD. Unfortunately, while doing the backup we had a "rolling blackout" (I'm in San Diego, where it was over 100 degrees F today). After the power was restored the MB1 would no longer boot from the 120GB drive. In the boot settings section of the BIOS, the option for Windows Boot Manager for the SSD is no longer there, and that is the option I believe that I need to be able to boot from the SSD.
While trying to figure out how to fix it, I reset the BIOS it to "Default Settings" and now the internal display shows only a vertical white line. I have the HDMI output connected to my television, and I see that the BIOS is now set for a much higher resolution display than the panel in the MB1, but I don't see a 1200x800 setting in the BIOS.
Can someone help me to restore the BIOS to the proper configuration? Also, does anyone know how to re-enable the Windows Boot Manager option as a boot selection? Thanks very much!
