Bug Description
Hardware: Dell Optiplex 9020, i5-4570, 32GB, Intel HD Graphics, Intel Corporation Ethernet Connection I217-LM, 6TB HDD
Operating system: Lubuntu 22.04.4 Release Candidate
Steps to reproduce:
1: Get a legacy BIOS system with a disk larger than 2TiB. (I have a 6TB spinning HDD.)
2: Boot the Lubuntu ISO in legacy BIOS mode.
3: Attempt to do an "Erase disk" installation.
Expected result: The installation should succeed.
Actual result: The installation crashes while trying to create partitions.
Additional information: Calamares is making an MBR partition table. This is the default behavior for BIOS systems. MBR partition tables only support 2TiB and smaller disks. When Calamares tries to create an over-2TiB partition during installation (in my case an over 5.4 TiB partition), it fails most likely because MBR can't handle that.
Note: This is not a regression. Older versions of Lubuntu 22.04 also defaulted to MBR as the partition table type for BIOS systems.

Couldn't this be resolved via me mention in release notes.
To me an install on >2TB on MBR wouldn't be expected to succeed (I may not expect it to succeed either; but failure>success in my expectation)
