Comment 8 for bug 657788

I don't believe that this bug was reported 7 months ago, and is still not fixed. THIS IS CRITICAL!
I tried upgrading from Ubuntu 10.10 to 11.04, and it lost EVERYTHING.
To the user, IT WIPES OUT THE DISK. There is no longer any Ubuntu. No way to get my files. Just a black screen that says

   GNU GRUB version 1.98-1ubuntu5

   Minimal BASH-like line editing is supported.
   For the first word, TAB lists possible command completions.
   Anywhere else TAB lists possible device or file completions.
   grub>

In order to have Ubuntu again, I needed to reinstall Ubuntu 10.10, BUT ALL OF MY FILES ARE GONE.
How can you ship something like this? Ubuntu used to be so nice and reliable.
Now I have to warn people that Ubuntu 11.x has a bug or virus that loses all of their files.
For people using this in production, they cannot just erase the disk and start all over. They have years worth of work, and it all gets lost in an hour while performing an "upgrade". They will really thank you for THAT!
