Reboot and install proper boot device?

[helloworld90]

I installed Ubuntu on my Toshiba laptop but when I go to the BIOS and select boot from the hard drive I get the message
"reboot and select proper boot device." How do I fixed this? the operating system I used to have was Windows 8 if that matters.

Did you install in legacy or UEFI mode? Your machine that came with Windows 8 used GPT partitioning on its disk, so if in legacy, you need a 2M grub-bios flagged empty partition, or if in UEFI you need aa 500M EFI FAT partition in addition to the root, swap partitions

May be best to see details, you can run from Ubuntu live installer or any working install:
Post the link to the Create BootInfo summary report. Is part of Boot-Repair:

What model Toshiba? Issues often common by brand, so other models may be similar.
