I managed to install Ubuntu 16.04.2 on a 32gb SD card plugged into an Asus x205ta. I made three partitions- one mounted at /, one mounted at /home, and swap space. When I try to boot, I get Error: No such device (long number sequence) entering rescue mode... grub rescue> I have searched the forums for answers, but none have worked. Boot Repair gave an error. Did I partition the disk correctly? Do I need to reinstall Grub2?
