two different disks used by a root partition?

Question

I have windows and linux dual boot, each of them in different physical disk. As i no longer need to boot to windows, how can i add that disk to linux root partition? Can a root partition uses two disks? Thanks.

Answer 1

You cannot "share" the root partition over two disks. You will need to mount the second disk somewhere.

Idea 1 - Use it as a drive from file manager

Format the disk using your favorite formatting utility and mount it in your file manager. This should be the easiest option.

Idea 2 - Use it for your /home folder

You could use this other disk as your /home by following the tutorial here: How to Move Home Directory to New Partition or Disk in Linux
