gptsync - GPT partition table to MBR partition table synchronisation
gptsync [-q] [-t] device
gptsync reads the GPT partition table on device and synchronises the
legacy MBR partition table with the GPT partition table. The MBR
partition table can hold only 4 partitions.
Legacy bootloaders or operating systems that do not support GPT require
an MBR partition table; this is typically the case when using GRUB or
LILO on an Intel-based Apple machine.
-q Do not print any message, do not prompt to modify the MBR.
-t Truncate partitions starting or expending beyond 2 TiB (MBR
limitation). Default is to ignore such partitions.
