My laptop is set up to dual boot Windows 10 and SL7. I had backed up all my Linux files and made a Windows 7 style backup of the Windows partition. Then I accidentally exited Windows by 'restart' rather than 'shut down'. The result is I cannot reboot the Linux. I get my usual grub menu but trying to start Linux from it gets (after a couple of warnings which are the same I had before): Welcome to emergency mode!..... and trying either of the suggested 'systemctl reboot' or 'systemctl default' leads to a message Error getting authority: Error initialising authority: Could not connect: No such file or directory (g-io-error quark,1) I can boot from a Live USB and mount the linux partitions. I am pretty confident therefore that no data has been lost from them. Is there a way to recover short of wiping the disk and reinstalling from the beginning? Malcolm MacCallum
