Helps to read the whole thing...

Your fstab is wrong so basic.target fails which is why boot fails. You
need to delete or comment out line 10 from fstab. And then you need to
put in a new entry for /home that uses the correct UUID. You can get
the correct UUID from the 'blkid' command. You'll use UUID because the
new home isn't on LVM, so you can't reference it with a device mapper
path like the existing one.

But really the simpler thing to have done originally is just leave
everything LVM and remove the SSD.
