Fedora Linux Looks to End Support for UEFI on MBR-Paritioned Disks

10 months ago

Fedora 43 may end UEFI support on MBR-partitioned disks for x86_64 systems.
The change enforces GPT partition tables for UEFI installations to improve reliability.
UEFI on MBR is unreliable and inconsistently supported by firmware.
Fedora's GRUB2 bootloader already assumes GPT for UEFI installations.
The change avoids bootloader crashes and efibootmgr failures.
Modern cloud platforms no longer require MBR-based UEFI setups.
The change applies only to x86 systems in UEFI mode; ARM and RISC-V are unaffected.
The proposal aims to reduce testing burden and enhance installation robustness.
The decision still needs approval from FESCo.
