Bug#675530: grub2-common: Missing '=root' in Windows 8 entry

[Waqqas Dadabhoy]

Package: grub2-common
Version: 1.99-22
Severity: minor

I installed grub on a computer already containing Windows 8 Consumer
Preview. When I select the windows entry in the grub list, it displays
"Error: no argument specified; press any key to continue", and pressing
any key boots grub fine.

Searching the error message indicates that this is due to "--set" being
used instead of "--set=root" in the entry. Looking at grub.cfg, I can
see "--set=root" in the linux entries, but not in the Windows entry, and
editing grub.cfg manually to include "=root" in the Windows entry fixes
the problem.
 
The Windows 8 entry is displayed as "Windows Vista (loader)" in the list.
(To prevent confusion for those reading the attached grub.cfg)
