Hello, forums.
Firstly, sorry for probably misleading thread name.
I am talking about the menu that pops up every time user get grub updates.
This menu writes for me "If you're unsure which drive is designated as boot drive by your BIOS, it is often a good idea to install GRUB to all of them."

In what universe should it be considered anyhow good idea? I mean, really, WTF?
It is generally BAD idea in at least one case (mine):
It puts up a menu with choices:
a) My Windows partition (which I don't need, but anyway it would broke it hardly)
b) My USB HDD (WTF?!?!)
c) My Live-USB with not so Linux live system (even if it was linux, grub whould have broken those. )
d) My BSD partition (WTF*2, Grub would have broken those. If in liveUSB area USB probably could boot with GRUB, this one could defenetely not)
e) My Windows rescue partition (see a))

If there is a package (grml) which detects installed systems and configures grub to use those, should'nt the grub-installer be aware of it and give no disaster-recommendations?

"User-friendly"? No, it is not. User should learn if he wants to update his base system (e.g. like 'If you unsure, check your bios settings"), or he should call a guy who knows what he's doing.
Or is this some kind of ubuntu philosophy I don't get?
