Hi I have another boot issue this and it's this when I boot my modified chromebox with Linux Lite as standalone os it boots slower than usual then when I pressed f4 the system hangs at "starting enable remaining boot-time encrypted block devices".  I googled that phrase and discovered a forum post in the Linux Mint bugs.launchpad.net site that said that in order to resolve this issue, I had to drop into recovery mode on boot, remount the root partition as read/write if necessary, edit fstab to fix or comment out the offending entry, save it and reboot. 

So rebooted my modified chrome-box and went into the grub menu and booted this distro's kernel in recovery mode and tried to edit fstab by remounting the root partition as read write and couldn't do it.  Along the way, I also discovered that terminal no longer works when pressing ctrl-alt-F1 nor does ctrl-alt-F2 nor with F3.  After trying to run fstab in recovery mode several times and discovering that it just sits there I googled this problem I found a workaround at this forum post http://unix.stackexchange.com/questions/44027/how-to-fix-boot-failure-due-to-incorrect-fstab whereby I see the contents of the fstab file add init=/bin/bash to the end of the kernel command line.  So I did what is on that post and got into the fstab file and saw the phrase which is the title of this post. 

Therefore, I googled "Kernel Panic- not syncing VFS: unable to mount root fs on unknown block (0,0)" to find a likely solution for this error and found this post in the Ubuntu forum dating back to 2012 a user by the name of lemon squeeze states that If you cannot get a root prompt at all, then get a LiveCD (the cd / usb key you used to install ubuntu should work) and boot from it. Then you have a useable system from which you can access the broken one.  http://askubuntu.com/questions/116635/kernel-panic-not-syncing-vfs-unable-to-mount-root-fs-on-unknown-block-oo-swapper.  So my question to you guys is this should I follow Oli's instructions to Boot to a LiveCD, select Try Ubuntu and then open a a terminal. Run the following:
sudo fdisk -l etc, etc in other words try to fix this my installed distro with an ubuntu live usb as shown in the you tube video :
