I installed a second SSD in my Dell laptop's optical drive bay. I want to install Ubuntu 18.04.4 to dual boot with Windows 10. I created a bootable USB with Rufus. I disabled Windows fast startup and secure boot in BIOS, set USB as first boot device, and checked UEFI mode (not legacy). Then, the installation starts normally.

I choose to install Ubuntu alongside Windows 10 (the first option... this option also creates an /dev/sda for NTFS and I don't know why...) and everything is fine until it says to restart the computer.

After restart, I see only the grub command line (as you can see in the picture below) and I don't know what to do.

If I use ls, I can see some partions but nothing else not even in partitons.

If I change boot priority, I can only boot Windows 10.

In BIOS, UEFI it says in windows SSD, in USB bootable (which was made with Rufus) and not in the SSD with Ubuntu.

How may I solve this so I can choose Ubuntu or Windows and successfully boot either?

  • I used boot repair and even though it was successfully repaired, you can see the report here, I still have the same problem.

  • I installed the ssd with Ubuntu in my desktop pc and it worked perfectly there... (I also have there, a separate ssd with windows 10 installed)

It sounds like there is some kind of problem with grub, the bootloader. Try booting off the USB stick again and use boot-repair as outlined here. That usually fixes most issues.

If that doesn't work, please post a link to the summary report boot-repair creates.

Good luck!
