Fedora Linux Looks To End Support For UEFI On MBR-Paritioned Disks
A proposal raised for Fedora 43 would end support for allowing UEFI installations on MBR-partitioned disks for x86_64 systems in the Anaconda installer
While the UEFI specification technically permits booting from MBR (msdos) disks, in practice this configuration is unreliable, inconsistently supported by firmware, and not tested in Fedora. By enforcing GPT in UEFI mode, Anaconda will provide a more robust installation experience by avoiding bootloader crashes (e.g., efibootmgr failures). These constraints no longer apply to modern cloud platforms, making MBR-based UEFI setups unnecessary for current Fedora deployments.
