[Bug 441941] Re: grub fails after running Windows

[Myname]

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:
http://www.chiark.greenend.org.uk/ucgi/~cjwatson/blosxom/debian/2010-08-28-windows-applications-making-grub2-unbootable.html

I hope you can help  and thanks in advance.

Bug description:
  Ubuntu 9.10 beta
  Grub

  After installing 9.10 beta, machine displays GRUB screen and allows rebooting into either Ubuntu or Windows.
  Both Windows and Ubuntu will load and run BUT, once you log out of windows, grub fails with only one line of text displayed - something like Loading GRUB. Computer is unusable - can't even Control-Alt-Delete. Must turn off and reinstall ubuntu.

  Usual method to restore GRUB is to run from the CD and fix grub from a
  terminal. This doesn't work in 9.10 with message "grub not installed"
