I'd like to know if the developers have any plan to support this feature officially in the future ? If so, when will it probably be implemented?
I think this feature is very useful, since some people have multiple OSes installed in multiple disks, and those OSes may have mixed BIOS/UEFI boot types. Without this feature, people have to go to the motherboard setup page to switch the BIOS/UEFI mode everytime he/she wants to switch to a different OS. thanks On Mon, Jun 2, 2014 at 12:01 AM, Andrey Borzenkov <[email protected]> wrote: > В Tue, 13 May 2014 09:32:57 +0800 > Z C <[email protected]> пишет: > > > rEFInd has this feature: It can load a bios bootloader despite running in > > uefi mode. > > > > I consulted grub documentation, and it doesn't mention whether grub > > supports this feature.
