I have an old-style MBR Grub configuration for F30. Converting the system to UEFI seems like a hassle and doesn't provide an obvious benefit for now (maybe next time I do a full install I'll go for it). However I also run Windows 10 in a KVM/QEMU virtual machine. This has its own dedicated drive and uses UEFI (OVMF). My BIOS supports UEFI and I've managed to dual-boot a few times by fiddling with the BIOS settings, but switching back and forth is clunky and error-prone, and Windows always wants to "fix" itself before working. My question is: how can I add this as an option to my Grub configuration to enable dual-boot directly from the Grub menu (i.e. running on metal, not a VM)? In other words, BIOS boots using MBR, invokes Grub, which then (optionally) invokes UEFI to boot Windows. Or is this not possible? poc
