Comment 191 for bug 441941

Hi, i got the same problem:
- no grub problem by default but after a log in windows the computer start to boot in a loop (computer reboots at the moment when grub should start);
- when installing grub I have the warning "Sector 5 is already in use by ZISD; avoiding it. This software may cause boot or other problems in future. Please ask its authors not to store data in the boot track".

I am running Unbuntu 11.04 and grub 1.99~rc1-13ubuntu3.
The boot is done on a RAID 5 array.

And finally you will find the files files attached as requested here:

I hope you can help and thanks in advance.
