"Error" setting up Dual boot with Windows 10 and Mint

[Akito]

@Trevor

Finally, I read somewhere else that the original Windows installation created too many partitions of a certain type, which means the Linux installation can only create the “Root and Swap” because of a limitation of 4 maximum ,that is a legacy from the DOS days.

This only applies to MBR disks. how to check if mbr or gpt at DuckDuckGo

HOWEVER here’s the problem, the remaing “Free Space” beocmes “Unusable” and is greyed out.

You should upload pictures of every error message and weird behaviour.

That said, you can read other guides here which could possibly help you additionally in achieving a correct dual boot setup: FAQ - Read before you post a request for help
