Comment 21 for bug 1024383

I've changed the title to something that I consider correct and appropriate as the last change was indeed incorrect.

Separately from the title, I wonder if it's possible to have a Windows installation which is bootable both via BIOS and via UEFI. If so, then it may not always be clear what type of entry to create at grub-mkconfig time and so it may be best to create both BIOS and UEFI based entries, but within an if statement that checks at boot to see if grub itself was loaded via UEFI or BIOS, and shows only the appropriate menu entry (this is currently possible, and not even difficult, to do with grub-script).

I don't know what to do though if we have for instance Windows installed in such a way that it can only be booted via BIOS, but Ubuntu's grub is being loaded via UEFI. In such a case there is nothing that grub can do to boot Windows, but just not showing the Windows entry is clearly not ideal. Possibly showing the Windows entry but giving a *clear* error message about why it can't be loaded is the solution there.
