1-It's Windows compatible. With it, Windows 7/10 won't refuse to complete updates
when it doesn't find something it expects in the partition table. "Refuse" in this
case means install a big heap of updates, then decide it can't finish, and wastes
more time uninstalling those it just installed, followed by announcing there are a
heap of updates to install, repeat ad nauseum.

2-The system was invented over 4 decades ago, before the PC compatible HD
partitioning system was upgraded to allow for more than 4 partitions per HD.

3-I have yet to intentionally install Grub2 on an MBR system. I use mostly
openSUSE's Grub Legacy, which supports ext4 (as long as 64bit is not enabled), on
all MBR systems, and Grub2-efi on UEFI systems, including Intel Mac.

UEFI is an incontrovertible improvement over MBR, but MBR will be around quite a
while yet for machines that don't include UEFI.

DFSee isn't a mere partitioner, and is not for MBR systems only. Among other
features, it's also a copier/cloner, a binary editor of files and raw sectors, can
be scripted, and it logs in plain text. Its logs are an indispensable part of my
environment, facilitating inventorying several hundred partitions and operating
systems spread across tens of uniquely partitioned and OS-equipped multiboot
machines. It includes free personal support from its author, as well as a helpful
support mailing list. It's interface is identical whether run from DOS, Linux,
Mac, OS/2 or Windows.
