Trying to fix partitioning on Chromebook

My friend tried installing Ubuntu as a dual-boot environment, but accidentally gave ChromeOS only 2 GB of free space.

He now can't increase the space of ChromeOS, and when we tried to recover it, but once he sets up the recovery USB, he can't recover ChromeOS because it complains that the partition has less than 4 GB of space..

Any suggestions?

EDIT: He has access to a working MacBook, internet connection, and USBs.

Assuming you're trying to create the recovery image on the Chromebook itself, then it's complaining that it doesn't have enough space to expand the image before writing it to the flash drive. You'll have to create it on a different device.

It doesn't sound like they are having a problem creating the recovery USB. But that they can't actually use the recovery that they created

It does sound like that, but I'm not sure we understand the OP's issue.

If the Recovery fails, it's likely due to an error downloading or writing the Recovery image. The Recovery process doesn't require any "free" disk space on the Chromebook to succeed, it just wipes everything as the first step.

I just recently used the Chrome OS recovery tool, and it didn't reclaim the partition that was created for GalliumOS. It was kinda tricky to resolve.

Unless something has changed, the Recovery process will start by writing a new full-ChromeOS partition table to internal storage, thereby "erasing" everything on disk.

(Note that Recovery and Powerwash ("Reset") are very different though -- Recovery requires downloading a ~1GB image and writing it to a USB/SD device, then pressing a special key sequence to boot from it)

If the newest versions of the Recovery image no longer reinitialize the partition table, then we will need to write some docs! :)

Was this on LILI? I can test the newest images on a few models, but not LILI or other Skylakes.

We don't have a problem making the USB, he has a MacBook.

That's what I thought. But my comments are down voted, lol

I am not having an issue with creating the recovery USB, he has access to a MacBook.

If I'm understanding you correctly, you need to create a bootable USB with GalliumOS on it, boot into GalliumOS and use a utility to reformat your partitions.
