So I'm trying to install ubuntu on a vm... I've come to the installation type page and I tried to just use the "erase disk and install ubuntu" option... When I do this it's saying that some of the partitions are too small and I have to go back and change them. I've installed ubuntu a few times and this has never happened. Any ideas how I can install and do I need to change anything? I'm a fairly virgin user so I have no idea what to do...
Which VM do you use? If I recall correctly you usually give the OS some kind of virtual partition when you insall it on a VM (VirtualBox usually asks for it before the installation). Probably your Ubuntu partition is too small to install the OS. I assume you have enough space on your hard drive to install it?
