I successfully installed to a new SDD via a USB installer, but grub install failed every time I tried, and I had to install it manually. I managed to figure out that the linux "/" dir was at /dev/sdc2 and configure my BIOS to use the right hard drive on boot, but it always puts me in the GRUB command line on startup. I have to type:

set root=(hd0,gpt2)
linux /vmlinuz root=/dev/sdc2 ro
initrd /initrd.img

Then my Ubuntu 18.04.2 LTS installation boots properly. What do I need to do so that GRUB gives me a menu of kernel version options--or even better, just starts up?


Please use Boot-Repair, it will definitely solve the issue. This will reinstall GRUB and add all other OS on the disk.
