titions in the legacy partition table and create a new GUID Partition Table (GPT). You only need
to do this once, so if you have done this before, you should skip this step.
The transcript below shows the user using the
gdisk
program to delete partitions defined in the
MBR partition table and creating a GPT (GUID Partition Table). Bolded text is user input. Before
proceeding to the next step, ensure that you have followed a similar procedure. The next step
will fail if an existing MBR partition table remains on the SD card.
$
sudo gdisk /dev/exb
GPT fdisk (gdisk) version 1.0.1
Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: not present
Found invalid GPT and valid MBR; converting MBR to GPT format
in memory. THIS OPERATION IS POTENTIALLY DESTRUCTIVE! Exit by
typing 'q' if you don't want to convert your MBR partitions
to GPT format!
Warning! Secondary partition table overlaps the last partition by
33 blocks!
You will need to delete this partition or resize it in another utility.
