I have done a standard Linux Mint install with encryption and LVM enabled. Then I have shrunk that LVM and created a separate /home using this guide such that I could easily reinstall Linux later without having to touch my /home.
Now I want to keep the LUKS and LVM and just reinstall Mint into that LVM, wiping my root directory but keeping /home.
What I've tried:
Run the Mint live CD again
Unlock my encrypted root and home partitions in nemo
Install the new system to the unlocked (encrypted) root partition and mounting all the other partitions/volumes to where they've been before
But after I restart the system, it won't boot and give back the error: "Volume group 'vgmint' not found"
