Yes, we are well aware this is a giant, complicated pain in the ass. (I suspect it would fall back transparently to BIOS/CSM mode if you try to boot a non-UEFI-capable medium with that switch set to ON, though). On your system it sounds like you just have a 'universal switch' for UEFI mode: if you have that ON and boot a UEFI-capable medium I expect it will boot in UEFI mode. Which mode you boot in is something you choose, ultimately, via the system firmware in some way it is difficult to be more specific than this because different firmware implementations offer it in very different ways. No OS installer can offer this option because by the time you reach the OS installer, the decision has been made. I don't see any other possibilties to boot an EFI boot manager.Ī.J: whether you are running UEFI or 'BIOS' (same thing as 'CSM', in case you're confused) mode is a choice made at boot time. Selecting the harddisk fires up grub as expected, but as I said without a windows entry. But selecting this, does not result in booting W8. This gives me a choice between my harddisk, DVD drive and an item 'Windows Boot Manager' which I presume is the EFI boot entry for W8. In this situation I can request the boot menu of the bios/EFI by hitting F10. From this I expect W8 to be installed in EFI and F19 to be installed in BIOS mode. After that I booted PXE and installed F19TC1 almost without specific user choices. W8 setup a few partitions and ended installation without failure. I assigned it 60Gb of the total of 240Gb of disk space. Then I put in the W8 CD, hit the reset button and let it boot. For the test I blanked the first few sectors of the harddisk with dd. In my Bios I only have one option "UEFI Boot" which I set to enabled.įurthermore nor in Windows installation nor in Fedora installation I made a deliberate choice wether to install in EFI or BIOS mode. > you still boot Windows from the EFI boot manager, however your firmwareįYI I have this issue on a Intel DH77KC motherboard.
