In Fedora Linux 43, systems with x86 architecture will only allow the use of GPT (GUID Partition Table) partition tables in all installations of Fedora using UEFI. This change has not yet been reviewed by the FESCo (Fedora Engineering Steering Committee), which is responsible for the technical aspects of Fedora's distribution development. If the proposal is approved, support for installing Fedora in UEFI mode on disks with MBR (Master Boot Record) partition tables will be discontinued on x86 systems, while remaining available on ARM and RISC-V systems.
The reason for discontinuing MBR support is cited as low boot reliability in such configurations, inconsistency in MBR support across firmware, and a lack of proper testing in Fedora (the GRUB2 documentation mandates the use of GPT for UEFI). It is expected that by keeping only GPT support in the Anaconda installer on x86 systems, crash exits during the boot phase caused by efibootmgr failures can be eliminated. Discontinuing MBR support will also reduce the burden on support personnel, simplifying maintenance and testing.
Ursprünglich wurde die Unterstützung von MBR im UEFI-Modus 2019 in Fedora hinzugefügt, um die Kompatibilität mit Cloud-Plattformen wie AWS zu gewährleisten, die GPT nicht unterstützen. Mittlerweile haben die Cloud-Plattformen dieses Einschränkung jedoch abgeschafft, sodass die Unterstützung von MBR in diesem Zusammenhang an Bedeutung verloren hat.
