Hello, during installation, I mistakenly assigned the second hard drive as the /usr directory. Now I have /usr as my second hard drive. And I cant add or move anything there since it's closed. Is there anything I can do? I dont want to reinstall the OS - a lot has already been done.
One option, if you have enough space, would be to partition your second hard drive. Then you can leave one part of it mounted as /usr and the remaining space you can mount somewhere else. This should avoid the reinstall. Gparted is a good tool to change your partitions and can be installed from the software centre. Note that /usr is where most of the linux software is installed, so it's good to have a fair amount of disk space there.
