Archinstall MBR error
Author: MickalebcCreated Sep 22, 2023Updated Sep 14, 2026
If you try to install Arch Linux on a machine that is using MBR and not GPT, and you use archinstall while having a drive bigger than 2 TB then the auto partitioning in the archinstall doesn't limit making partitions to match the requirements of MBR. It tries to make partitions that are much bigger than 2 TB and total of 2TB limit need to be added to the auto partitioning. Say you have a 4TB HDD like I do then it tries to make a 3+TB partition on the drive which will cause the install to fail. This makes the installer not compatible with older machines.
