How to resize Chromium OS data partition to maximum?

I've installed Chromium OS from by downloading an image file, uncompressing it, and writing the uncompressed image to the hard drive.

Chromium OS boots and works just fine. However, fdisk shows than only 2 GB is allocated for the data partition, even though the hard drive is much larger (>200 GB).

How do I get the data partition resized to the maxiumum possible size, so that it fills the hard disk?

I've tried:

• , but it doesn't work: it tried to assign negative size to the ROOT-C partition.

• says that partition resizing is initiated by the system, not by the user. How can I force this resize? (Also the page seems to be out of date, last update was in 2009.)

before you flash your hdd make 2 partitions (first one for nonchromium os, second for blank space) make sure format of hdd is recognizable by unix>linux file system, flash first partition

Look at the this gh repo: imperador/chromefy. They have a dual boot script that should work for your case.
