Unhidding the partition to boot

[Arbiel Perlacremaz]

Hi

When a Windows partition is hidden, it turns out that trying to boot it will fail. This is apparently the case for Windows 7 as well as Windows XP. 

The hiding of the partition may result from a blunder of the user. However, this blunder can easily get fixed by the insertion of the command

parttool ${root} hidden-

between the search and the linux command of the menuentry

I run a test, and it works perfectly.

Can somebody update the /etc/grub.d/30_os-prober to distribute this modification.

Thanks

Arbiel
