Disclaimer: I am very new to Linux (1 week).
I have installed the Valve version of Steam on LMDE6. I have used Disks to automatically mount the NTFS drive I used with Windows (doesn’t hold bootloader, it is just for Steam library storage) at boot ( /media/[username]/Gaming ) and I made it the default library folder in Steam.
Running games works perfectly (actually, performance is surprisingly good), but I cannot install them due to a “disk write error”.
I looked for solutions and found this page, from which I understand that I need to change permissions to the mounting point, but when I do, using chown -R, I get a “Read-only filesystem” error for all files and folders.
I can see no options to fix this in Disks and I tried to edit fstab once, but it messed things up so badly I had to use the USB drive with the portable installer to fix things.
Yes, it is a transitional dual boot setup. Will be trying to pass to exFAT as suggested elsewhere for working on both. Then when I will figure out what hardware would be most compatible, I will eventually remove the dual boot and fix things accordingly.
