Hello! I am having the same issue. I have Windows 10 installed, and wanted to have Ubuntu as well. I followed the steps described on Ubuntu forums, however it cannot install Ubuntu because it requires an EFI partition, which is not possible to me since I have a legacy BIOS and that cannot be changed to UEFI.
Last time I tried to "force" install Ubuntu, I ended up not being able to boot in any of the OS's. During the manual partitioning, I thought that creating a specific "/boot" partition would be enough to solve the problem, but it was not, unfortunately.
