# gptsync(8)

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.

## AUTHOR

**gptsync** was written by Christoph Pfisterer.
