Stumbled across this today while searching for a fix for a PC running 16.04 that this is happening on. I don't understand why, but editing /etc/default/grub to uncomment the line for graphical terminal fixed it. What that has to do with mounting root I don't know, but that was certainly the fix.
I noticed that I could hold shift and select the same kernel, with the same command line options, under the advanced menu and get the system to boot. Uncommenting #GRUB_TERMINAL=console fixed it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1547559 Title: Kernel panic - not syncing: VFS: Unable to mount root fs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1547559/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
