Gparted says the sda5 is mounted and that it can't delete any mounted partitions. Then it tells to unmount the partition. But the partition does not show that it is mounted, and when I right-click to unmount, it does nothing. Even when I click to mount sda5 it does nothing. Even when I boot from the disk, either from Trisquel disk or another disk, e.g., Puppy or whatever, it won't delete that sda5 partition when I try to run the partition manager and wipe everything and start over.
I opened a terminal and used sudo and su... sudo gave me a bunch of "usage" gibberish and that was it. "su" gave me a password entry point, and when I put in the password it said, "su: Authentication failure". The only password I have given the machine is the one I put to it when I installed, the same one I use to log in at boot. And that password works just fine for that. So what password is needed is beyond me. I don't know of any other passwords.
Thanks for your help!
