I'm new to Linux, but just loaded and installed Ubuntu 16.04.2 on my nephew's HP Pavilion Laptop (15-n037ncl).
Everything seems to be working fine except that the USB flash drive I used is now recognized as the primary drive, and I can't seem to figure out how to install and boot from the internal SSD. When I remove the USB drive and try to boot, it says there is no OS recognized.
Any help is greatly appreciated.
test -d /sys/firmware/efi && echo efi || echo bios
Knowing the boot mode helps us help you.
