This is the second time I tried installing Mint on my PC. First time the installer stalled and went nowhere for 40 minutes, second time I’m missing the first option for dual booting. My trust in Linux isn’t the highest right now.
Edit: I was able to get it working. I just shrunk my D: drive by 100GB, for some reason that made it work.
Your drive is encrypted. You either need to disable that, or boot back into Windows and shrink the partition and clear up space to install.
The only other option the installer sees with no free space is take over the entire drive.
