I'm running Mint 17 Mate on an Intel I7 machine, 3 physical drives, 2 HDs & 1 SSD. I was learning to use the virtual terminal & couldn't escape from it, & ultimately rebooted only to find myself back in the same place. I'm not sure what all I did, but after booting it wouldn't respond at all to the keyboard. Eventually I tried to get rid of the partition on that drive which I didn't know was essential. So, when I boot from the liveDVD Mint, I can see the system files on that drive, but my personal files are completely absent; the home folder is empty. gparted shows the drive as almost empty whereas it was nearly full. It makes no sense to me that the system files are there but my files are gone.
