There is a guide here that says you can do it, but my experience was that I installed the games in Windows on my D drive, mounted the drive in Linux (Mint, I think), and when I tried to play them The system locked up. Rebooting into windows, Steam said the game files were corrupt and I had to reinstall them. I’ve always just kept two separate game libraries on any dual boot systems ever since.
