Grub Corrupts NTFS Volume Should it be sda1

[bsfmig]

Binary package hint: grub2

1.Update Grub by using standard package management methods.
2.Grub automatically installs its boot sector into /dev/sda as has been set and done multiple times.
3.When update-grub executes, the Windows Boot Manager item disappears.
4.Reboot and Ubuntu no longer recognizes the file system.
5.Reboot into Windows PE and it reports the partition as "RAW".
6.Use Windows chkdsk.exe (7600.16385) utility to check the partition, and it says "Unable to read the first NTFS boot sector or it's corrupted." After a thorough "fsck", the partition is well back again.

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.
