The 1023 cylinder limit is BIOS limit for booting. If your BIOS is more
modern it will support booting from translated cylinder addresses >
1023. The easiest way to tell is to try updating your BIOS, and trying the
install.
With older hardware I would have to have boot partitions all located at <
1023 cylinders so you'd have the / partition and a windows c: drive both <
1023 on a dual boot system. This limit has mostly disappeared with more
modern BIOS that will address and boot drives at > 1023.
