Ubuntu: Can't start any OS after installing Ubuntu


I've been a windows 10 user, and I've just installed the lastest version of Ubuntu, on another hard drive (always connected to the computer). Now I can't start any OS, not even the bios will start so I can't start from a USB stick or DVD. I've unplugged the HDD containing Ubuntu installation, and since I still can use Windows, but I don't know how to be able to use the drive again. Do you have an idea? Many thanks!
