How to hide recovery partition from Grub2

Question

I've installed a Linux distribution on a friend's PC. He does not know how to use Linux or even Windows very well, and I'd like for it to be as easy as possible. When I installed GRUB, it detected his recovery partition that HP installed for him, and its the first Windows in the list.

After some googling and looking through the grub manual and config files, I still can't figure out how to hide a partition from GRUB. I looked at 30_osprober, but didn't see any clear way to exclude an OS.

Can anyone point me in the right direction for excluding an OS / patition from the GRUB menu?

Thanks, Sam

//EDIT// Changed due to edits(I swear this changed while I was typing)

A dirty solution is to edit the grub.cfg, but this would need to happen every time a kernel upgrade happened.

In grub v2: (NOTE THIS IS NOT RECOMMENDED)

vim /boot/grub/grub.cfg

The correct way to accomplish this is to edit /etc/grub.d/30_os-prober(as you mentioned) and tell it to ignore certain partitions, a good guide can be found here

Dirty solution #2 could be to run a script that comments out that line from the the grub.cfg for your buddy.
