Dual boot with Windows 10 installation error

The way that has always been successful for me was to use the windows disk manager and shrink the file system/partition, leaving the space I wanted for linux as unallocated . Then when I install linux into that empty space it just works.

I’m sorry if I explained it incorrectly, but I did it like this (you can see it in the first screenshot in the original post, where the 78.13 GB space is unallocated.)
