GPT partition table to MBR partition table synchronisation

NAME

gptsync - GPT partition table to MBR partition table synchronisation

SYNOPSIS

gptsync [-q] [-t] device

DESCRIPTION

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.

OPTIONS

-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.
