I am new to this OS. I am installing it on a 8GB stick right now. I guess I just boot to it? there is no way to modify the disk space when installing on hard drive. it only used 512mb out of a over 500GB drive. telling me it was already using 40% of the first partition right and end of install. that's crazy, they need to allow us the change partition size. anyhow i ran across your post and wanted to input what I am experiencing. I guess I can install a OS on the laptop after the install to the USB drive. no OS on it now.
During first boot, whether it's installed on hdd or from a flash drive, it resizes to utilize the entire drive. First partition is the read only system partition, that stays the same. Data partition is mounted as /storage
