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.
If your CPU supports TPM2.0 and tou set up Windows using a Microsoft Account, your OS Volume is likely to be encrypted with Bitlocker.
