Hi Roberto,

yes, there just seems to be a version mismatch, so most likely a part
of Grub2 gets restored.

[root at moonstudio src]# ./bootinfoscript /tmp/bootinfo.txt 

Boot Info Script 0.61      [1 April 2012]
[snip]
[root at moonstudio src]# grep Grub2 -A2 /tmp/bootinfo.txt 
 => Grub2 (v1.99) is installed in the MBR of /dev/sda and looks at
sector 1 of the same hard drive for core.img. core.img is at this
location and looks in partition 97 for .

Between "97" and the "." there unlikely should be just a space.

[root at moonstudio src]# dpkg -l grub-pc | grep ii
ii  grub-pc        2.02~beta2-36ubuntu3 amd64        GRand Unified
Bootloader, version 2 (PC/BIOS version)
