Hi @maxdruiz, I don't have the time to figure this out at this moment. I haven't tried this script on Chromebooks in recent years and I'm not sure if there have been some changes to disk layout or similar. If not, unit conversions (B <--> GiB) and arithmetic should be all that's needed to understand what's going on, if you want to try yourself.

Otherwise, you might try resizing with chrx or parted instead and see if those work without issues.

Feel free to report back and share your findings or what works. :)

Trip report, for those who may have found this via searching:

I tried this, and while it gave the same error, the script did modify the partition table & successfully made empty space after the stateful partition.

Subsequently booted into a gparted live image, made an ext4 partition (#13) in the free space, rebooted, and allowed ChromeOS to repair itself.

Following this, I booted into a Debian live image and installed Linux on the new partition. After fiddling with edk2 bootloader to properly register the location of grub.efi, I now have a dual boot chromebook! So: it is possible to switch between Linux and ChromeOS with the built-in legacy firmware, which was enabled through Mr.Chromebox's scripts. ChromeOS seems to tolerate the 13th partition just fine.
