So I guess I messed up my Ubuntu Server just now.
I installed a 500GB hard drive, formatted it with ext4 and then wanted to statically mount via editing /etc/fstab and the UUID.
For some reason I somehow removed the '-' in the UUID because I don't know why. So after rebooting now i get the following:
"Gave up waiting for root device. Common Problems: - Boot args (cat /proc/cmdline) - Check rootdelay = (did the system wait long enough?) - Check root = (did the system wait for the right device?) - Missing module (cat /proc/modules; ls /dev)ALERT! /dev/mapper/server--vg-root does not exist. Dropping to shell!"Then I get a very limited BusyBox shell.
What I've tried so far is booting with a live USB Ubuntu desktop and mounted the Boot drive but when accessing it there are only the Kernel versions and grub and some more stuff, but not the root files "/etc, /usr, /home, etc" otherwise I'd just have undone the changes to fstab and tried but I don't even get there.
