Dividir o HD através do ENDLEss

tenho uma maquina com dual boot windows no ssd e HD no ENDLESS gostaria de particionar o HD pra liberar um pouco de espaço para arquivos do Windows.

Unfortunately, the image file created by the Endless OS installer (which resides in C:\endless) is not meant to be shrinked, so you’re probably out of luck. If you really need to free up some space, you’ll have to go the route of backing up required files from Endless OS and then uninstall/reinstall with a smaller size.
