Is my BIOS somehow configured to boot in EFI mode?? I checked and /sys/ >firmware/efi does not exist so... Is it something in the MBR? What could it be?
Hi! I'm guessing you're seeing the following message? "Some EFI-based systems are buggy and do not handle new bootloaders " "correctly. If you force an extra installation of GRUB to the EFI removable " "media path, this should ensure that this system will boot Debian correctly " "despite such a problem. However, it may remove the ability to boot any other " "operating systems that also depend on this path. If so, you will need to " "make sure that GRUB is configured successfully to be able to boot any other " "OS installations correctly." If so, that message will be coming from the grub postinst script, but should *only* be triggered if you're installing grub-efi-$ARCH and you have a /boot/efi/ tree.Or are you seeing a different message? -- Steve McIntyre, Cambridge, UK.
