Bug#514263: thinks that my ext2 root filesystem is fat

[Chris McRaven]

I experienced exactly the same problem as described in Messages #5 and 
#17.  In fact my hexdump of the first 512 bytes of my /dev/sda1 produced 
exactly the same hexdump described in Message #17. 

The workaround for me was to copy all of the files from the /boot 
partition, run mkfs.ext2 on it, and re-copy the files back onto it.  
After doing this, `grub-probe /boot` returns "ext2".

Grub2 now works fine.

Cheers.
