I've been a windows user since 2010 and I started using Linux as the host OS 3 months, so far so good. I was just wondering if there is a way of creating a partition that is not under the root partition in Linux. Like in windows, if say Local Disk C was to corrupt and you had to reinstall the Windows again, the data in the other partition would still be safe. How can you do about that in Linux?
